3. UNDERSTANDING THE UNIT
The Abso Charger is a fully automatic negative grounding multistage battery charger with the ability
to charge 3 separate battery banks. When first connected to an AC power source, the charger will
check all three battery banks before charging commences. The charger operates on an isolated
charging design where Battery Bank 1 is separate from Battery Bank 2 and 3. Battery Bank 1 is the
priority battery bank in the charging sequence and is recommended to be connected to the main (or
primary house) battery bank. Battery Bank 1 can be programmed with a different charge algorithm
from Bank 2 and 3 (including different battery chemistries like GEL, Flooded, AGM, Lithium or
Program battery type and different charging current). Battery Bank 2 and 3 can also be programmed
identically to Bank 1 or to any other type that is available on the setting list.
The Battery Banks 2 and 3 are always connected in parallel internally (with a separation diode) and
share a common charge algorithm.
During normal operation, the charger will do a full charge cycle to float stage on Battery Bank 1. Once
the float stage is reached, the charger starts charging Battery Banks 2 and 3 together with a bulk and
absorption mode. On completion, all the three battery banks move to float stage with a shared battery
voltage determined by Battery Bank 1 float voltage settings.
The Abso Charger also come with a unique feature that when the battery charging sequence starts,
if it senses either Battery Bank 2 or 3 have battery connected andthe battery voltage is below 11V on
12V model (AC12100)or below 22V on 24V model (AC2450), it will cycle to charge Bank 1 for 15
minutes then Bank 2 and 3 together for 15 minutes and cycle. When the charger senses both Bank 2
and 3 reach 13V on 12V model (AC12100)or 26V on 24V model (AC2450), it will then concentrate
on charging Bank 1 until it reaches the float stage. After, it will then concentrate on recharging Bank
2 and 3 (together) to float stage. On completion, all three battery banks move to float stage with a
shared battery voltage determined by Battery Bank 1 float voltage settings.
During the float stage each battery bank is isolated by an internal separation diode.
There is another unique feature Silent Mode whereby the charger has the ability to reduce fan speed
at night or whenever required. This setting can be manually turned ON and OFF through the display
and remains active for a period of 12 hours.
The charger also has the ability to awaken on over discharged Lithium battery with output terminated
by the internal BMS circuitry. This manual activation function will awaken a lithium battery that has
shut down due to under-voltage.
Important Note: The battery Bank 1 on the charger should only be connected to the main battery
bank for first priority charging and the battery Banks 2 and 3 on the charger are to be connected to
the other battery banks with lower priority (such as jump-start battery bank and/or AC generator
battery bank used in a marine application). On single bank installations, it is recommended to use
Bank 1 on the charger

Typical wiring block diagram of the Battery Charger with 3 battery banks
•AC Source:
The charger accepts full universal input voltage (90-265Vac, 47-63Hz).
•Branch Breaker:
For use on 120V AC Input source,use a 15A branchbreaker to connect betweenthe AC Source
and the charger AC Input hardwire cable (Hot–black wire, Neutral–white wire, Ground–green
wire).
For use on 230V AC Input source, a minimum of 8A branch breaker is required from the AC
Input Source.
•Battery Bank 1, 2 & 3:
There are a total of three channels (CH1, CH2, CH3) available for charging three battery
banks (Battery Bank 1, Battery Bank 2, Battery Bank 3).
•Chassis Ground:
The unit chassis has to be grounded properly to the common ground point on the system.
•Digital Remote (optional):
The Display Remote (Part Number: ACRM1202) sold separately is used to provide unit
information from the charger. It is used as a secondary display to provide charger information.
This can also be used as a main display or controller to connect two AC Chargers of the
same model running in parallel.
•Battery Temperature Sensor –BTS (optional):
The Battery Temperature Sensor BTS (Part Number: BTS-10K) sold separately is designed
to use on Battery Bank 1 (CH1) for better battery charging performance. The sensor is also
used to terminate the battery charging process when it senses the battery temperature is
either too high or too low and is not suitable for charging.

Understanding the Multi-Stage Charging Process:
The charger is a fully automatic “set-and-forget” design. It is designed to quickly and accurately
recharge deep cycle batteries utilizing charger algorithms that helpto maximize the life of specialized
deep cycle batteries.
The charger features a multistage smart charging technology that enables the charger to be
connected to the battery banks permanently.
As dictated by battery manufacturer’s recommendations, deep cycle batteries require a multi-stage
charge sequence for perfect, fast and accurate charging. This charger delivers four primary charge
stages (Bulk Charge, Absorption Charge, Float, and Maintenance).
Typical charging profile of the charger
•Bulk Charge ‘bUL’: The battery is charged at a full rated output current of the charger until the
battery reaches the final charging voltage, known as its absorption voltage. In this step, around
80% of the battery is recovered as fast as possible. During theBulk charge stage, an 8-hour timer
is started when the battery voltage reaches approximately 13.5V. This timer is set to avoid battery
overcharging. The charger will override the Absorption to Float stage condition and goes to Float
stage when it times out.
•Absorption Charge ‘AbS’: With the charger voltage held steady, the remaining 20% is replaced
with the charger allowing the current to drop as the battery approaches its full charge. There is a
4 hour time limit on Absorption stage to avoid battery overcharging. The timer will override the
Absorption to Float stage condition and goes to Float stage when it times out.
•Float Stage ‘FLo’: Finally, inthe float stage, the charger voltage islowered and held at a constant
and safe predetermined level. This prevents the battery from being overcharged, yet allows the
charger to supply enough current to make up for the self-discharge losses of the battery while
supporting any additional loads connected to the battery (such as DC lighting and refrigerators).
This stage allows the charger to be used as a DC power supply.
•Maintenance: This is a regular timed recharge (or return to the bulk stage). The charger switches
from float stage to bulk charge after 7 days of constant operation to ensure the battery banks
remain active.

5. UNIT OPERATION
Understanding the Battery Charging Current Setting:
The battery charging current rating is based on the battery size. When charging GEL, AGM and
Flooded batteries, each battery bank should meet the minimum Ah rating as shown on below chart.
If a smaller size battery bank is used, set the current rating to a lower value to match with the battery
bank size. Normally, the maximum charger current rating is based on half the battery bank capacity.

When charging a Lithium battery, consult the Lithium battery manufacturer for maximum allowable
charging current.
In float stage, the charger can provide a maximum float current of 60A for AC12100 and 30A for
AC2450.
Understanding the Digital Display:
•‘GEL’, ‘AGM’, ‘Flooded’, ‘Lithium’and ‘Program’icon represent different battery type settings.
•With only ‘CH1’, icon turned on, the numerical value on the display shows individual battery
information like battery voltage and charging current.
•With ‘CH2’ and ‘CH3’ icons turned on together, the numerical value on the display shows the total
charging current to both battery banks.
•During normal operation, the display shows the related channel’s battery voltage, charging current,
and charging stage (Bulk-‘bUL’, Absorption-‘AbS’) alternately.
•When all channels have reached Float/Full stage, the display starts showing ‘FUL’indicating that
all the batteries connected are fully charged.
Understanding the ‘INFO’, ‘NEXT’and ‘SET’Function Keys
Under Normal Operation (with AC Input connected):
‘INFO’: Press and hold the key for longer than 3 seconds to enter the charger setting mode and
display will show unit setting. Use ‘SET’ key to toggle the available settings. Press ‘NEXT’
key to keep and save the chosen setting (thedisplay will quickly flash 3 times to acknowledge
the setting is set). The display will then show the next menu to continue with other setting
parameters.
‘NEXT’: Press the hold the key for longer than 5 seconds to RESET the charger. Display will show
‘RST’ and it will force the charger to restart the charging cycle again starting with Bulk mode.
The charger can also be RESET by disconnecting the AC Input, waiting for 5 seconds and
reconnecting the AC Input again.
‘SET’: Press and hold the key for longer than 3 seconds to activate the Silent Mode operation and
‘Auto’ icon will show on the display to acknowledge the operation is in place. Press and hold
the ‘SET’ key for longer than 3 seconds to cancel Silent Mode operation and ‘Auto’ icon will
turn off. For details, see “Understanding and Executing the Silent Mode Function”
With No AC Input connected:
‘INFO’: Pressing and holding the key for longer than 3 seconds will temporarily turn on the display
for about 10 seconds and the display will show battery voltage for all 3 channels. This feature
is useful to know what battery banks are actually connected to the unit. If “0.6V” or “0.7V” is
read on the channel, it would mean that there is no battery connected to that battery bank.
The display will then show the charger revision number (e.g. ‘r1.0’). Please mark down the
revision number as this information may be required if you call for customer service.
Understanding the Two-Stage (Mode 2) and Three-Stage (Mode 3) Charging Functions:
Mode 3 Charging:
The Three-Stage Charging (Mode 3) has a Bulk,followed by Absorption, and then Float sequence.
During the Bulk stage, the battery accepts the maximum constant current from the charger. In the
Absorption stage, the battery voltage is held to constant voltage and the charging current will slowly
reduce. In Float/Full stage, the charger continuously produces lower constant Float voltage to fully
top up and maintain the battery in a fully charged state.
The charger will automatically restart the full charging cycle if it senses any one of the battery banks
is discharged to lower than 12.5V for 12V model, 25.0V for 24V model or after seven days in Float
stage to refresh the battery banks.

Page 14
Mode 2 Charging:
The Two-Stage mode 2 charging is similar tothe Three-Stage charging except that there is no Float
stage after the Absorption stage. The charger will terminate the battery charging after Absorption
stage.
The charger will automatically restart the full charging cycle if it senses any one of the battery banks
is discharged to lower than 12.5V for the 12V model, 25.0V for the 24V model, or after seven days
since the last Absorption stage to refresh the battery banks.
Understanding the Battery Temperature Set Functions:
For use when Battery Temperature Sensor is NOT in use:
CAUTION: RISK OF BATTERY DAMAGE. If the temperature sensor is not being used, never set
the battery temperature lower than the actual temperature. This may overcharge and damage the
batteries.
There are three manual battery temperature settings available on the unit for GEL, Flooded and
AGM batteries.
•Low temperature ‘Lo’, setting for when the battery is charging in a low temperature environment.
•Normal temperature ‘nor’, setting is for when the battery is charging at room temperature.
•High temperature ‘HI’, setting is for when the battery is charging in a high temperature
environment.
With different settings above, the battery charging voltage is adjusted as listed below.

For use when Battery Temperature Sensor is in use:
No setting on the unit is required, and the unit will automatically sense the Battery Temperature
Sensor when it is connected to the BTS Port and the manual battery temperature setting on the unit
will be over-ridden by having the Battery Temperature installed.
•Use with GEL, AGM, or Flooded Battery Type Setting:
The battery sensor installed on Battery Bank 1 will monitor the Battery Bank 1 battery
temperature and will make small adjustments to the battery charging voltage on CH1 for better
battery charging performance.

The sensor is also used to terminate the battery charging process when the battery temperature
drops to below -25°C andthe charging process will resume again when battery temperature rises
to above -20°C. It will also terminate the charging process when the battery temperature rises to
above 70°C and the charging process will resume again when the battery temperature drops to
below 60°C.
•Use with Lithium or Program Setting:
The battery sensor installed on Battery Bank 1 will monitor the Battery Bank 1 battery
temperature. It is used to terminate the battery charging process when the battery temperature
drops to below 0°C. The charging process will resume again when battery temperature rises to
above 5°C. It will also terminate the charging process when the battery temperature rises to
above 60°C and the charging process will resume again when the battery temperature drops
to below 55°C.

Procedure to Equalize Flooded Battery:
DANGER: Explosion Hazard. The battery generates explosive gasses during equalization. Follow all
the battery safety precautions listed in the manual. When using the equalization mode, the user has
to be sure the battery connected to the channel is a flooded battery type. Equalizing a non-flooded
battery may overcharge battery and cause the battery to explode.
CAUTION: Risk of Battery and Equipment damage. Only a Flooded lead-acid battery can be
equalized. Consult your battery manufacturer or read the battery manual when you try to equalize
your batteries.
Disconnect any DC load connected to the battery, as during equalize mode, the charger will produce
15.5V on 12V model, or 31.0V on 24V model to the batteries. The equalized voltage may damage the
DC connected tothe battery. You must monitor the battery specific gravity throughout the equalization
process to determine the end of the equalizing cycle.
Before setting the equalization mode on the specific channel, please be sure the battery connected
to the specific channel is a flooded battery type. When the battery equalization process started, the
charger will automatically fully charge the selected channel first and follows with 1 hour of 15.5V
equalization process. Consult or follow theinstruction as provided by the battery manufactureron how
to check the battery electrolyte level and or refill with distilled or deionized water during the 1 hour’s
equalization period. All cells should have similar electrolyte levels. If distilled or deionized water is
added, batteries must undergo a complete charge cycle.
The charger cannot determine when to terminate the equalization of the battery. A one-hour timeout
is set as a safety feature by requiring the user to continually re-activate it as necessary after checking
the batteries manually. During the equalization mode, the other two battery banks are disabled.
Procedure to Awaken Over Discharge Lithium Battery
Some Lithium ion batteries have BMS circuitry that turns the battery off when over discharged. The
charger may not recognize a battery is connected and start the charging process. To awaken the
Lithium battery, press and hold ‘INFO’ and ‘SET’ buttons for 5 seconds. The charger will provide
13V (with 10A current limit) to the battery terminal for 10 seconds. If battery voltage was measured
at the terminal after 10 seconds, the lithium battery is awakened, and the charger will restart the
charging process. If no voltage was measured at the terminal, the charging process will terminate.
This function works only on Lithium battery setting.

Tips: Use this function during nighttime or when a quiet environment is needed. Please also note
that the charging time will increase in this mode because the charging current may be derated.
This function can switch to ON or OFF at any time during the charging period.
To set this function, press and hold ‘SET’key for 5 seconds to execute the Silent Mode. The ‘Auto’
icon will show on the display. To turn this function off, press and hold the ‘SET’function for 5 seconds
to turn off Silent Mode. The ‘Auto’icon on the display will turn off and the charger current and the
fan speed will return to normal.
Note: the charger will automatically depart from Silent Mode after 12 hours from being set.
Procedure to Change CH1 to Power Supply mode
•Set CH1 to Program mode setting.
•Press and hold ‘INFO’ and ‘NEXT’ button for 5 seconds
•Display will show ‘P’ for approximately 5 seconds to indicate Power Supply mode is activated.
•The charger will supply the set Absorption voltage in Program mode with 100A current limit at
CH1 and the display will show the supplied voltage and the supplied current alternately.
•To cancel Power Supply mode, press and hold ‘NEXT’button for 3-5 seconds to reset the
charger and CH1 will return to charging the battery with Program mode.
Note: Power Supply mode can only be used on CH1 only.
Understanding the Protection Features
Derating the Charging Current: When the charger senses the environmental temperature is above
50°C, the maximum charger current will de-rate to 1/2 of the value (A02 warning code will display).
The charger will recover automatically back to the maximum charging current when the
environmental temperature drops to below 45°C.
Over Temperature Shutdown: When the charger senses the environmental temperature is above
60°C, the charger will shut down. It will recover automatically when the environmental temperature
drops to below 45°C.
Battery Reverse Polarity: When a reverse polarity is connected to the battery bank, Fault Code E03
on display will appear. In some case, the user replaceable DC fuse located near the DC Output
terminals may blow and Error code E08 will display.
AC Input VoltageProtection: The charger will shut down when itsenses the AC input voltage is outside
of the operatingrange. A faultcode will display. The charger will recoverautomatically whenitsenses
the AC input voltage has returned to the normal operation range.
Disconnecting the Battery Bank: To avoid any spark on the battery terminal, always disconnect AC
Input before removing or disconnecting the battery.
BTS Shutdown (with optional BTS in use): To avoid any battery damage especially when a Lithium
battery is used, the charging cycle will be terminated when the optional BTS senses the battery
temperature is out of the charging range.
Charging Batteries with Low Voltage
The charger is designed to charge batteries with voltages on their terminals greater than 3Vdc on 12V
model and 6Vdc on 24V model. For lower voltages, the batteries can be temporarily and partially
charged using the charger’s Power Supply mode under Program setting, before returning to the
proper battery type setting. Please noted the Power Supply setting can only be used on CH1.
Reinitiating the Charging Cycle and the battery connection status manually
The charging cycle can be reset or reinitialized at any stage. Press the hold the key for longer than 5
seconds to RESET the charger. Display will show ‘RST’ and it will force the charger to restart the
charging cycle again starting with Bulk mode. The charger can also be RESET by disconnecting the
AC Input, waiting for 5 seconds and reconnecting the AC Input again.
