Vencon UBA 5 Specification sheet

The UBA (Ultimate Battery Analyzer) is a battery analyzer, charger, discharger and reconditioner. It’s also a data
logger, thermometer and electronic load . Wow! That’s a lot of stuff in such a small box. How do we do it? Easy. We
get the PC to do most of the work.
The first three chapters in this guide show you how to setup the UBA then takes you step by step through a complete
battery analysis. Once you’ve done your first battery analysis, you can use the online help that comes with the UBA
Software to learn more. We recommend that you read these first three chapters before you run your first battery
analysis (it won’t take that long).
Notes:
● The latest version of software and online help is available at the private area of our web site. To get there, run

1. Setting Up The UBA
● Unpack the UBA shipping box and check that you’ve received the following:
● The UBA battery analyzer, charger, and conditioner.
● Vencon UBA Console CD, which contains the software for the UBA.
● A 2 metre 9 pin male to female shielded serial cable.
● Two sets of test leads with alligator clips.
● A printed copy of this guide.
● A power supply (if you purchased a UBA Combo).
What you need to get started (in addition to the above):
● A power supply (included with the UBA Combo).
● A PC with a free serial port or a USB port and a USB to serial converter.
1.1. Connecting the UBA to a Power Supply
The UBA requires a power supply with a DC voltage from 15 to 24V (see section 5.1 “Choosing and Setting Up a
Power Supply” for more information). Connect the power supply output cable to the back of the UBA and plug the
power supply’s AC cable into a wall outlet. The battery red LEDs will flash once, the fan will spin a couple of times and
the power LED will turn on. If this doesn’t happen then check the voltage on the power cable: it should be at least 15V
with the centre pin positive.
If you use your own power supply ensure that it has a 2.1mm DC barrel plug that mates with the power input on the
back of the UBA. The UBA is reverse voltage protected, if you reverse wire the DC supply cable no damage will result,
but the UBA won't turn on. Also ensure that the power supply voltage is no more than 25V no-load, otherwise you risk
damaging the UBA.
The UBA Let's Get Started Guide Page 1

1.2. Connecting the UBA to a Computer
The UBA connects to any unused serial port the PC. You can use a USB port with a USB to serial port converter -
contact us for purchase information. Connect one end of the supplied serial cable to the UBA (the connector marked
“RS232 from Computer or other UBA”) and the other end to the PC serial port or USB converter.
1.3. Connecting More than One UBA to a Computer
If you are using more than one UBA, then connect the first one to the PC as described above and the second UBA to
the first UBA. No adapters or gender changers are required. Repeat this for any additional UBAs (the maximum is
253 UBAs per serial port, but performance and memory limits are reached before that). Each UBA requires its own
power supply or they can share a single power supply with enough current to power them all. You can connect the
UBAs while they are on, but you will have to re-initialize the UBA network for any new UBAs to be recognized.
1.4. Extending the Serial Cable
You can extend the UBA's serial cable with a shielded extension cable. We have successfully run the UBA with a 30m
(100ft) cable. Check for resent commands in the communication port display (accessible from the UBA Network
window by right clicking on the comm port). You really shouldn't have any, but if you do, don't worry as the UBA uses
advanced error correction so that any corrupted transmissions are resent.
Figure 2: Communication port display showing UBAs connected and the number of commands sent and resent
(commands are resent if there is a communication error). Here 21 million commands were sent without error.
This is an actual image from our burn-in station where UBAs are run for at least 12 hours.

1.5. Ventilation
The UBA can generate up to 90 Watts of heat during a battery discharge or charge. Do not obstruct the air holes on
the top or bottom. Be careful when touching the UBA during a high current discharge or charge, as it can get quite hot
(the fan automatically turns on when the UBA gets too warm). Avoid running a high power discharge or charge when
the UBA is in a hot environment (greater than 30 degrees Celsius).
It is normal for the UBA to get get warm (some might call it hot) before the fan turns on. You can check that the fan is
functioning by watching if it turns on when power is applied to the UBA or during network initialization or you can turn it
on from the Multitester instrument (described later). If you would prefer that the fan turn on earlier, there is an option
for this in the Options... menu (under File, click on Options... and select the General tab).
1.6. Battery Cables
Figure 3: Connecting a battery to the UBA. The UBA uses standard
banana jacks for its battery connections and comes with two sets of battery cables with alligator clips. Additional plugs
or cables are available from us. Plug the cables into the front of the UBA and connect the red clip to the positive
terminal of the battery being tested and the black clip to the negative terminal of the battery.
NOTE: The UBA inputs are polarity protected, thus connecting the battery backwards will not damage your battery,
nor the UBA.
CAUTION: When the battery cables are connected to a battery but not plugged into the UBA, the banana plugs can
touch each other resulting in very high currents potentially causing burns or the battery might gas or explode. For this
reason, we recommend that the banana plugs be plugged into the UBA before connecting them to your battery. In our
lab banana plugs connected to a battery, when not connected to a UBA, are inserted into a piece of wood with 11/64”
(4.5mm) holes that keep the plugs safely apart.
Figure 4: Using a block of wood to keep battery banana plugs from shorting.
Hint: If you expect to be testing cylindrical cells (like AA, AAA, C, ...) then consider using battery connectors
with magnets. Contact us for ordering information.

2. UBA Console Installation instructions
The software that runs on the PC and controls the UBA is called UBA Console. Install it on a PC running Microsoft
Windows (Win95 or later) or Linux (we have an application note on our website explaining how to do run UBA Console
under Wine).
Windows 95 and NT users: If you will be installing UBA Console on a PC with a fresh install of Windows 95
or NT then you might have to install the HTML help application and some other upgrades to your operating
system. See the troubleshooting section at the back of this guide.
2.1. Installing UBA Console
Insert the UBA CD into the PC’s CD drive. Installation should start automatically. If it doesn’t, run SETUP.EXE on the
CD. If you’re installing from a file that you downloaded from our website, then run that file.
Important -- Data Location:
During the installation you will be asked where to locate the “application's database”. This folder, called VenconUBA,
is where the files containing battery analysis routines are stored as well as where the analysis results are stored. By
default it's put in the same folder as UBA Console, i.e.:
C:\Program Files\Vencon\VenconUBA <- default (not recommended)
We recommend you choose a different location which is regularly backed up. For example on our PCs we put it in My
Documents:
C:\Documents and Settings\UserName\My Documents\VenconUBA <- recommended
You can change the folder location after UBA Console has been installed by moving (or dragging) the VenconUBA
folder to the new location then specifying it on the Folder tab in the Options dialog box (File menu).
The following four folders are created in the VenconUBA folder:
AnalysisResults – Analysis results are stored here.
BARs – Battery Analysis Routines are stored here.
Page 4 The UBA Let's Get Started Guide
Figure 5: Example folder paths.

Database&Cal – Database, calibration, and sound files are stored here.
Logs – Log files are stored here.
2.2. Starting UBA Console
Start UBA Console (accessible from the Windows Start menu).
Figure 6: UBA Console - UBA Network not yet initialized.
If you don’t get this, see Appendix A - Troubleshooting.
Don’t be surprised if your version of UBA Console appears slightly different then this as we’re always improving the
software.
2.3. Initializing the UBAs
UBA Console is now running, but its not yet communicating with the UBA. For that to happen, you have to initialize the
UBA Network. Tell the software which comm port(s) to use on the Serial Port tab in the Options dialog box (File
menu). Only free comm ports are displayed. You can choose more then one comm port, UBA Console will check
them all for a UBA each time you initialize the UBA network.
You can initialize the UBA Network by clicking on the first icon on the main menu (the “on/off” switch) or by the other
ways shown below.
Figure 7: Multiple ways to initialize the UBA Network.
Either way UBA Console will try to connect to the UBA using the serial ports that you have selected. You can close the
UBA Network window by clicking on the Close button or the X(this does not close the UBA network).
The UBA Let's Get Started Guide Page 5
Four ways to initialize the UBA
network:
Right click here or here.
or click here or here

2.4. Locating and Installing the UBA Calibration File(s)
Every time UBA Console initializes a UBA Network, it reads the calibration file for each UBA that it detects. If it can’t
locate the calibration file in the VenconUBA\Database&Cal folder, it will put up a Calibration file not found dialog box.
Every UBA comes with a calibration file that can be found on the installation CD or it was emailed to you. Once
located, UBA Console copies it into the VenconUBA\Database&Cal folder so that it can find it next time.
Don’t lose the UBA’s calibration file, but if you do, don’t panic. We keep a copy. If you’ve made it so far you should
see this:
Figure 8: UBA Console with the UBA network initialized (icons are enabled).
UBA Console has now established communications with the UBA(s) and you can start any instrument.
3. Is My Battery any Good? The Battery Analysis
In this chapter, we're going for a quick tour of the UBA and to run a battery analysis. Start up UBA Console and
initialize the UBA Network.
3.1. The Multitester
Before starting a battery analysis, let’s do some exploring. Click on the third icon, which starts the Multitester. The
Multitester is a great place to start, as you can check the battery’s voltage and the operation of the UBA.
Figure 9:
UBA Console ready to start an instrument. Click on the circled icon to start a Multitester.
Page 6 The UBA Let's Get Started Guide

This is what the Multitester looks like:
Figure 10: Multitester Instrument. Use it to monitor the battery voltage while applying a
load or charge current, plus other functions.
With a battery connected, if the Multitester says 0V (zero volts) then check the connection to your battery – it should be
connected to channel one with the correct polarity.
For this test don’t use a battery pack that has any protection circuitry inside that might interfere with the testing. You
can test those batteries once you are comfortable using the UBA.
For this example, I am using a four cell 600mAh NiCd battery.
Enter a small test current (100mA for example) into the load or charge current edit boxes and click the corresponding
Set button. The battery voltage should rise a bit if you set a charge current or drop a bit if you set a load current. This
verifies that the UBA charger and load are functioning and that you have a good connection to the battery. Note, you
can’t run the load and the charger at the same time.
Besides applying a load or charge current, the Multitester can also do a constant voltage charge, a quick test
(measures battery internal resistance), or read the UBA temperature probes (if connected). Press F1 for more
information from the online help. Experiment with some of the options.
Warning: The Multitester does not check the suitability of the charge or load current that you are using. Unless you
know your battery’s condition, you should limit the charge and load current to just a few seconds so you don’t damage
it.
Close the Multitester window so that you can start a battery analyzer on that channel: it is not possible to run two
instruments on the same channel at the same time.
3.2. Setting Up the Battery Analysis
Open a battery analyzer by clicking on the battery analyzer icon on the tool bar.
The UBA Let's Get Started Guide Page 7
More options include:
Constant voltage and PWM
Sets the charger to the requested
current, or turns it off.
More options include:
constant resistance and power.
Sets the load to the requested
current, or turns it off.

Start a battery analysis.
Figure 11: UBAConsole: Starting a battery analysis. Click on the circled icon.
This opens up the Start a Battery Analysis dialog box:
Figure 12: Start a Battery Analysis dialog box: Entering analysis parameters.
There are three sections that need to be filled in before you can start the analysis.
Battery Parameters: Number of Cells and Capacity
Enter the number of cells (in series) and rated capacity of the battery. For battery packs the rated capacity and
nominal voltage should be printed on the pack. Calculate the number of cells by dividing the nominal pack voltage by
the nominal cell voltage.
Page 8 The UBA Let's Get Started Guide
Choose a BAR
Choose filename to store results.
Battery Parameters

Battery Chemistry Nominal Cell Voltage (Volts per cell)
NiCd or NiMH 1.2 V
SLA, lead acid or gel cells 2 V
Lithium ion or lithium polymer 3.6 V
Same battery examples:
12V Lead Acid 6 cells
4.8V NiCd or NiMH 4 cells
7.2V NiCd or NiMH 6 cells
9.6V NiCd or NiMH 8 cells
12V NiCd or NiMH 10 cells
3.7V Li-ion or Li-polymer 1 cell
7.4V Li-ion or Li-polymer 2 cells
Sometimes the battery pack manufacturer prints a nominal voltage that’s a bit higher then the standard values, in this
case round down the number of cells to a whole number.
In general, NiCd, NiMH, lead acid and gel cell battery packs have all the cells in series. Therefore, the number of cells
that you enter is the number of cells in the battery pack and the capacity is the capacity of each cell, not the sum of the
capacity of all the cells (i.e. the cell capacity is the same as the pack’s capacity). For example, the following pack,
which consists of three 1Ah cells, has a rated capacity of 1Ah and a cell count of three.
Lithium-ion packs can have cells in parallel and series. The number of cells that you enter is the number of cells in
series and the capacity is the rated capacity of the pack (sum of the capacity of parallel cells). For example, the
following pack, which consists of six 1Ah cells, has a capacity of 2Ah and a cell count of three.
The UBA Let's Get Started Guide Page 9
Figure 13: Example battery pack. Pack capacity: 1Ah, cell count: 3.
Figure 14: Example battery pack. Pack capacity: 2Ah, cell count 3.

Note, you have to enter a battery capacity, even if it's not required for the BAR that you'll be using. For example, if you
are using the Datalog BAR you can enter any value for the capacity – 1mAh works fine.
Battery Analysis Routine Filename
The battery analysis routine (BAR) contains a sequence of actions that describe the battery analysis that is to be
performed. UBA Console includes BARs that you can use right away. Click on the folder icon beside the BAR
filename to display them. Select the BAR you want to use and click Open.
Select NiCd Test with Peak Charge, NiMH Test with Peak Charge, or SLA Test depending on the chemistry of the
battery that you'll be testing. Note, lithium batteries have a nasty habit of exploding or catching fire if over charged,
they should be tested in a fireproof container.
In Chapter 4 Creating a Battery Analysis Routine I’ll show you how to create your own BARs.
Hint: Double clicking on the BAR filename will open that BAR in the BAR designer.
Analysis Results Filename
In the Analysis Results Filename edit field, enter a filename to store the analysis results. I suggest that you use a
filename that contains information describing the battery you’re testing. For example, use the job number, warranty
return number or battery serial number.
Comments (optional)
Enter any comments that you would like stored in the battery analysis results file; for example, “This battery was
returned by a customer who says that it doesn't work.”. You can edit the comment text in the results file after the
analysis ends using a text editor.
3.3. Starting the Battery Analysis
Once you’ve entered in all the parameters, start the battery analysis by clicking on the Start button. If the Start button
is grayed out then some information is missing or the channel is being calibrated. The battery analysis window should
look like this:
Figure 15: A running Battery Analysis.
The battery analysis is now running. The buttons on the tool bar offer the following options in order:
•Restart the battery analysis (grayed out while battery analysis is running, click on stop first).
•Stop the battery analysis.
•Skip to the next step in the battery analysis.
Page 10 The UBA Let's Get Started Guide

•Show the results graph.
•Hide this window (use Active Instruments on the Instruments menu to redisplay).
•Show the starting parameters.
Right click on this battery analyzer window and select Grow (or Show More Information) for more information.
Figure 16: Battery Analysis window (after right clicking on it and selecting Grow).
Hint: hold your mouse cursor over the Discharged value for percentage discharged, double click on it to
change the displayed value to percentage. Double click again to switch back.
3.4. Monitoring the Battery Analysis
Note that in this example the battery analysis starts in discharge. This is the default behavior of most of the BARs that
come with UBA Console. When the battery voltage reaches the cut-off value (the voltage where the battery is
considered fully discharged) the load is shut off and the charging starts (sometimes after an optional rest).
Click the View Results icon on the tool bar to get a graphical view and summary of the progress so far.
The battery analysis is finished when either the word “Finished” appears or the battery is in trickle charge (assuming
that trickle charge is the last action in the BAR).
3.5. Interpreting the Results – Is My Battery Any Good?
When the analysis is over, press the View Results icon on the tool bar to get a graph of the battery voltage and the
test results. If you've closed the battery analysis window, you can view the results from Battery Analysis Results File
Viewer from the File menu.
The UBA Let's Get Started Guide Page 11

Summary of events and test results.

The analysis that I received is shown on the next page. During the discharge portion the battery voltage follows the
classic NiCd/NiMH form: an initial fast drop in voltage, a gradual decrease as the battery loses its charge, and a fast
drop at the end when the battery is fully discharged. After discharge, the charger is turned on and the battery voltage
rises quickly as it recovers, then rises gradually as the battery accepts the charge, and then peaks when it’s fully
charged. The voltage drops after the peak as the charge current is reduced from the 600mA peak charge current to
the 60mA equalization charge current.
Figure 17: Sample battery analysis result of a discharge followed by a charge cycle.
Now look at the text below the graph. In the One Hour Discharge: section you can see that the battery with a rated
capacity of 600mAh, was discharged 580mAh. This battery tested at 97% of rated capacity (580mAh / 600mAh x
100%). A battery with a capacity of over 90% of its rated value is considered in good condition. One with between
80% and 90% of its rated capacity is acceptable, however one below 70% to 80% should be replaced (these figures
depend on the battery and it's intended application). For the discharge capacity to be used as an acceptance criteria,
the battery must be fully charged before the test. The NiCd and NiMH BARs that come with UBA Console run for two
cycles, the first cycle leaves the battery fully charged so that the next cycle can give an accurate result. For SLA and
lithium batteries either start the test with a fully charged battery, edit the BAR so that the discharge follows a charge or
run the BAR twice.
Page 12 The UBA Let's Get Started Guide
“Battery discharged” is the tested
capacity of the battery.

In the Peak Charge section notice that the battery was quick charged for 738mAh. This is greater than the measured
capacity of the battery, which is to be expected since charging is always less than 100% efficient. This also means
that the battery received the full peak charge and didn’t false peak. A false peak is a voltage peak that can occur
during the beginning of the charge cycle. It normally occurs on a new battery or a battery that hasn't been cycled in
over a couple of months. Also a poor electrical connection to the battery can cause a premature peak. Had the
charged capacity been less than the discharged capacity then, most likely, something interrupted the charging, and the
battery wasn’t fully charged. The 3h Equalization Charge is programmed for 3 hours at 60mA which equalizes the
cells and ensures that each one is 100% charged.
Note: for this example we used a simplified version of the “NiCd Test with Peak Charge.bar” BAR with just one
discharge and one charge cycle.
Conclusion:
This battery is in good condition. Cycle it regularly to keep it effective and replace it when its capacity drops to below
70 or 80%.

Congratulations! You've completed a battery analysis. You now know how to setup and initialize the UBA, start a
battery analysis and interpret the results. The next stage is to create your own BARs so that you can get the UBA to
do exactly the analysis that you want.
4. Creating a Battery Analysis Routine
I consider the battery analysis routines the most exciting part of UBA Console. We designed the battery
analysis routine from the ground up to be so powerful and expandable that you'll be able to analyze your
batteries using methods that you never thought possible -- this has certainly been our experience. Once
you've used our battery analysis routine designer you'll never want to go back to the old "fill in the blank" type
of battery analysis.
Marc A. Venis P.Eng., M.A.Sc
President Vencon Technologies Inc.
The Battery Analysis Routine (BAR) Designer allows you to create a battery analysis using graphical techniques.
Once you learn the basics of how to design a simple BAR, you'll be able to design your own advanced BARs that can
form, recondition, and life test batteries, create and erase memory in NiCd/NiMH cells, and many other advanced
functions.
Let's create a simple BAR: a NiCd battery test based on IEC (International Electrotechnical Commission)
specifications. From the UBA Console main window select Battery Analysis Routine Designer (File menu). You
should get an empty routine like this:
The UBA Let's Get Started Guide Page 13

Figure 18: An empty BAR (Battery Analysis Routine).
We want our BAR to first charge the battery, so we'll add a quick charge cycle or action. Actions are the building
blocks of the BAR. There's no limit (except for screen size) to the number of actions that a BAR can contain.
Right click on the gray background and choose: NiCd/NiMH | Add Cycle | Quick Charge Cycle.
Figure 19: Adding a new action (Quick Charge Cycle) to the BAR.
Now add a standard charge cycle by right clicking and choosing NiCd/NiMH | Add Cycle | Standard Charge Cycle.
Finally add a cycle that will discharge the battery and measure its capacity. Right click again and choose
NiCd/NiMH | Add Cycle | Discharge Cycle.
Now would be a good time to save what you’ve done. Choose Save As... (File menu) and save the file as NiCd IEC
Test. You should get this:
Figure 20: The BAR with actions (action parameters not yet specified).
The BAR starts at the "Begin" circle and proceeds from left to right to the "End" circle. Each action is executed in this
left to right sequence. Click Animate (Window menu) to see this.
Page 14 The UBA Let's Get Started Guide

Now to get this BAR to actually analyze a battery you need to set the charge and discharge values. Click on the NiCd
Quick Charge action and enter the parameters as shown below.
Figure 21: Charge Action: Entering the charge current parameters.
Now click the Finished tab to enter the parameters that determine when the quick charge cycle ends.
Figure 22: Charge Action: Entering the finished parameters.
The UBA Let's Get Started Guide Page 15
Enter “10” for the Sample Time.
The battery voltage and charge
current will be saved every 10
seconds to the results file.
Enter “1” for the Charge Current
which gives a current of 1C.
This will charge the battery in
approximately one hour.
Enter “1.3” for the Maximum
Charge Capacity. Thus quick
charging will end when the battery
has been charged 1.3 times its
rated capacity. This is a fail safe
feature to limit over charging.
Click on the Peak Charge
checkbox. This adds a Peak
Charge page.

Figure 23: Charge Action: Entering the peak charge parameters.
Click OK to save the changes.
Repeat for the NiCd Standard Charge action but use these parameters:
•Charge Current: 0.1 C (this is a slow C/10 charge that equalizes the cells without overcharging).
•Write to results every: 30 seconds (saving the results more often than this gives no additional useful
information).
•Capacity (fraction): 0.3 (at the C/10 charge rate this gives about 3 hours of charge).

Now click on the NiCd Discharge action and fill in the fields as show below:
Figure 24: Discharge Action: Entering the discharge current parameters.
Click the Finished tab:
Page 16 The UBA Let's Get Started Guide
Load:
Select Relative.
Enter “0.2” for the Discharge Current.
This is the IEC standard and will
discharge the battery in approximately
five hours.
Enter “30” for the sample time. Since it
will take five hours to discharge the
battery it's not necessary to save the
voltage and current more often then this.
Enter “10” (mV/cell) for the
Peak Charge finish criteria. Thus
when the cell voltage drops 10mV
below its peak value, charging
stops.
Enter “0.05” for the
Minimum Charge so that during
the first 5% of the charging any
voltage peaks are ignored. This
skips false peaks that can occur
at the beginning.
