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.
IMPORTANT SAFETY INFORMATION
This section contains important safety information for the KISAE Abso Charger. Each time,
before using the unit, READ ALL instructions and cautionary markings on or provided with the
unit, and all appropriate sections of this guide. The KISAE Abso Charger contains no user-
serviceable parts. See Warranty section for how to handle product issues.
WARNING: Fire and/or Chemical Burn Hazard!
Do not cover or obstruct any air vent openings and/or install in a zero-clearance compartment.
WARNING: Failure to follow these instructions can result in death or serious injury. Keep
away from children!
•When working with electrical equipment or lead acid batteries, have someone nearby in case
of an emergency.
•Study and follow all the battery manufacturer’s specific precautions when installing, using and
servicing the battery connected to the charger.
•Wear eye protection and gloves.
•Avoid touching your eyes while using this unit.
•Keep fresh water and soap on hand in the event battery acid comes in contact with eyes. If
this occurs, cleanse right away with soap and water for a minimum of 15 minutes and seek
medical attention.
•Batteries produce explosive gases. DO NOT smoke or have an open spark or fire near the
system.
•Keep unit away from moist or damp areas. Never expose unit to snow, water etc.
•Avoid dropping any metal tool or object on the battery. Doing so could create a spark or short
circuit which goes through the battery or another electrical tool that may create an explosion.
WARNING: Explosion hazard!
•Do not use the unit in the vicinity of flammable fumes or gases (such as propane tanks or
large engines).
•Avoid covering the ventilation openings. Always operate unit in an open area.
•Prolonged contact to high heat or freezing temperatures will decrease the working life of the
unit.
CAUTION:
•This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety.
•Children should be supervised to ensure that they do not play with the appliance.
•Do not charge non-rechargeable batteries because of the danger of eruption.
•During charging, batteries be placed in the ventilated area.
•The battery terminal not connected to the chassis has to be connected first.
•The other connection is to be made to the chassis, remote from the battery and fuel line. The
battery charger is then to be connected to the supply mains.
•After charging, disconnect the battery charger from the supply mains. Then remove the
chassis connection and then the battery connection.
•Only allow children at least 8 years old to use the battery charger. Give sufficient instruction so
that the child is able to use the battery charger in a safe way and explain that it is not a toy

and must not be played with.
•The child does not try to charge non-rechargeable batteries because of the danger of eruption.
•Examine the battery charger regularly for damage, especially the cord, plug and enclosure. If
the battery charger is damaged, it must not be used until it has been repaired.
FCC INFORMATION

3. UNDERSTANDING THE UNIT
The KISAE Abso Charger is a fully automatic 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 must be connected to the main (or primary house)
battery bank. Battery Bank 1 can be programmed with a different charge algorithm over Bank 2
and 3.
Battery Bank 2 and 3 are 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
with battery type set to either GEL, AGM, FLOODED or LITHIUM (see Lithium section for
limitations of use). Once float stage is reached the charger transition to charge Battery Banks 2
and 3 together with a bulk / absorption mode (Battery Banks 2 and 3 can be set to either GEL,
AGM or FLOODED). On completion all three battery banks move to float stage with a shared
battery voltage determined by Battery Bank 1 settings. This setting allows the charger to remain
permanently connected to mains if required. See more details on Appendix B.
Important Note: Battery Bank 1 on the charger should only be connected to the main battery
bank for first priority charging and Battery Banks 2 and 3 on the charger 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 marine application). On single bank installations DO NOT use
Battery Bank 2 and 3.
