1. INTRODUCTION
Thank you for purchasing the KISAE Abso Charger . With our state of the art, easy to use design, this
product will offer you reliable service by providing a multi-stage multi-bank battery charger to charge
different types of batteries you have installed in your boat, RV, vehicle, or your cabin battery bank.
An innovative feature we offer is the ability to charge your main battery bank as first priority so that you
may charge this main bank quickly. Another unique feature is our silent mode setting that reduces the
charging current at night, thereby reducing the fan noise.
This manual will explain how to use this unit safely and effectively. Please read and follow these
instructions and precautions carefully.

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 and the 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
