the battery.
• A KISAE Abso Charger Temperature Sensor (sold separately) is available and is used to
connect to one of the battery terminals. It measures the battery temperature and will make
small adjustments to the battery charging voltage for better battery charging performance.
• If the temperature sensor is not used, you can also manually set the charger to Low, Normal,
or High to reflect the environmental temperature for better charging effect. See more details
on Understanding the Battery Temperature Function in Section 5.
Digital Display:
• ‘CH1’, ‘CH2’ and ‘CH3’ represent Battery Bank 1, 2 and 3
respectively. With individual icon turned ON, the
numerical value on the display shows individual battery
information like battery voltage in ‘V’ or charging current in
‘A’.
• ‘GEL’, ‘AGM’, ‘Flooded’, ‘Lithium’ and ‘Program’
represent different battery types setting.
• ‘Auto’ indicates silent mode is activated.
• ‘Priority’ indicates priority battery bank charging is
activated
• ‘Mode’ only turns on during the setting of charging stage (Mode 2 – 2 stage: Bulk and
Absorption mode only, or Mode 3 – 3-stage: Bulk, Absorption and Float charging).
• ‘Temp’ only turns on during the setting of battery temperature.
Battery Charger Voltage:
Battery Type Absorption Float Equalization
GEL 14.2 V 13.8 V N.A.
AGM 14.3 V 13.4 V N.A.
Flooded 14.4 V 13.5 V 16.0 V(See Note1)
Lithium Constant 14.2 V, 14.3 V, 14.4 V (See Note2) N.A
Program
(Power Supply)
Constant 13.3 V, 13.5 V, 13.7 V (See Note3) N.A
Note 1: Equalization setting can only be used on flooded battery type selection only. See more
details on Procedure to Equalize the Flooded Battery.
Note 2: Charger will terminate charging when charging current drop to below the set charger
termination value.
Note 3: Charger is acting as a power supply with selected constant output voltage and preset
maximum output current. With this setting, only Bank 1 can be used, Bank 2 and 2 is
disabled.
Battery Bank Size Recommendation:
The battery charging current rating is based on the battery size. Each battery bank should meet
the minimum Ah rating as shown. If a smaller size battery bank is used, set the current rating to
lower value to match with the battery bank size. Normally, the minimum battery bank capacity is
based on twice the charger current rating.
