the unit is powered up. When all four LEDs are lighted, it indicates a fully charged battery. As
the battery capacity drops, so will the lighted LEDs. Each LED indicates approximately 25% of
the battery capacity remains:
RED, YELLOW, GREEN and BLUE LEDs LIGHTED = FULL BATTERY CAPACITY
RED, YELLOW and GREEN LEDs LIGHTED, = 75% BATTERY CAPACITY
RED AND YELLOW LEDs LIGHTED = 50% BATTERY CAPACITY
RED LED ONLY LIGHTED = 25% OR LESS BATTERY CAPACITY
BATTERY METER CALIBRATION:
Inside the unit is a small jumper that can be set to three different positions corresponding to
three different battery chemistries (voltages). The jumper is factory set to monitor Lithium Ion
batteries (14.8Volt nominal voltage) This setting is the most common as it is correct for most of
the newer lithium NP-1 batteries and all of the new lithium "Smart" batteries. There are also two
other settings. One setting is for use with 12.8-volt batteries such as sealed Lead Acid (SLA) and
Lithium Iron Phosphate (LiFEPO4). The other setting is for use with Nickel Metal Hydride
batteries (some older NP-1s). If you want to use the non-factory standard battery monitoring,
you must remove the top cover of the unit by removing the 14 screws located on the top cover.
