WARNING AND SAFETY NOTES WARNING AND SAFETY NOTES

Connect the batteryto the terminal of the charger:red is positive and black is
negative. Due tothe difference between resistance of cable and connector, the
charger can notdetect resistance of the battery pack,the essential requirement
for the chargerto work properly is that thecharge lead should be of adequate
conductor cross-section, andhigh quality connectors which are normallygold-
plated should befitted to both ends.
Always refer tothe manual by the battery manufacturerpertaining to charging
methods, recommended chargingcurrent and charging time. Especially, the
Lithium battery shouldbe charged according the charging instructionprovided
by the manufacturerstrictly.
Attention should bepaid to the connection of Lithiumbattery especially.
Do not attemptto disassemble the battery pack arbitrarily.
Please get highlightedthat Lithium battery packs can bewired in parallel and in
series. In theparallel connection, the battery’s capacity is calculated by
multiplying single battery’s capacity bythe number of cells with totalvoltage
stay the same.The voltage’s imbalance may cause fire or explosion .Lithium
battery is recommendedto charge in series.
A batterypack which consists of different types of cells(including different manufacturers)
A batterythat is already fully charged orjust slightly discharged.
Non-rechargeable batteries (Explosionhazard).
Batteries that requirea different charge technique from NiCd, NiMh, LiPoor Gel cell
(Pb, Lead acid).
A faultyor damaged battery.
A batteryfitted with an integral charge circuitor a protection circuit.
Batteries installed ina device or which are electricallylinked to other components.
Batteries that arenot expressly stated by the manufacturerto be suitable for the currents
the charger deliversduring the charge process.
Please bear inmind the following points before commencing charging:
Did you selectthe appropriate program suitable for thetype of battery you are charging?
Did you setup adequate current for charging ordischarging?
Have you checkedthe battery voltage? Lithium battery packscan be wired in parallel and
in series, i.e.a 2 cell pack can be3.7V (in parallel) or 7.4V (inseries).
Have you checkedthat all connections are firm andsecure?
Make sure thereare no intermittent contacts at anypoint in the circuit.
Charging
During charge process,a specific quantity of electrical energyis fed into the battery. The
charge quantity iscalculated by multiplying charge current bycharge time. The maximum
permissible charge currentvaries depending on the battery typeor its performance, and can
be found inthe information by the battery manufacturer. Only batteries that are expressly
stated to becapable of quick-charge are allowed tobe charged at rates higher thanthe
standard charge current.

WARNING AND SAFETY NOTES
Discharging
The main purposeof discharging is to clean residualcapacity of the battery, or to reduce
the battery’ voltage to adefined level. The same attention should be paidto the discharging
process as charging.The final discharge voltage should be set up correctly to avoid deep-
discharging. Lithium batterycan not be discharged to lowerthan the minimum voltage, or it
will cause arapid loss of capacity or atotal failure. Generally, Lithium batterydoesn’t need
to be discharged.Please pay attention to the minimumvoltage of Lithium battery to protect
the battery.
Some rechargeable batterieshave a memory effect. If they are partly used and recharged
before the wholecharge is accomplished, they remember thisand will only use that part
of their capacitynext time. This is a ‘memory effect’ It is saidthat NiCd and NiMH batteries
are suffering from memory effect. NiCd has more memory effect than NiMH.
Lithium batteries arerecommended to be discharged partially ratherthan fully discharged.
Frequent full dischargingshould be avoided if possible. Instead,
charge the batterymore often or use a batteryof larger capacity. Full capacitycannot be
reached until ithas been subjected to 10 ormore charge cycles. The cyclic process of
charge and dischargewill optimize the capacity of batterypack.

The screen displays the nominal voltageof Lithium battery.There are three
kinds of Lithium battery: LiFe(3.3V), Lilo(3.6V)or LiPo(3.7V). This is very
important so you have to checkthe battery carefully and set itup correctly. If
it is different from correctvalue the battery may be explodedduring charge
process.
B6 Ultimate recognize the cell count of Lithium battery automatically at
the beginning of charge or dischargeprocess to avoid from erroneous settingby
user. But deeply dischargedbattery can be perceived incorrectly. To prevent the
error, you can setthe time term to verify thecell count by the processor. Normally,
10 minutes are enough to perceivethe cell count correctly. For the battery of larger
capacity, you mayextend the time term. But ifyou set the time term toolong for the
battery of smaller capacity, the charge or discharge processcan be finished within
the time term with the erroneouscell count. This may causethe fatal result.
If the processor recognizes the cellcount incorrectly at the beginning ofcharge or
discharge process, you may extend thetime. Otherwise, you had better usewith
the default value.

This program is only suitable for charging Pb lead-acid battery with nominal voltage from 2 to 24V.
Pb lead-acid battery is completely different from NiCd/NiMH battery.These batteries can only
deliver current lower in comparison to their capacity.The same restrictionapplies to the charging
process. Consequently,the optimum charge current can only be 1/10 of the capacity.Pb battery can
not be used for fast-charging, please follow the instructions provided by the battery manufacturer.
Due to the chemistry characteristic of Pb battery,the cut offpoint may be difficult to detectsometimes.
We recommend userto use CAPACITY CUTOFF feature to protect the battery. You can press START/
ENTER key to make it blink and alter the value of parameters using INC or DEC key, press START/
ENTER key to store the value.
