BATTERY FUEL GAUGE INDICATIONS
When your Battery Fuel Gauge is activated, the battery fuel gauge provides battery pack status information utilizing three red
LED indicators, three amber LED indicators and three green LED indicators.
Battery Fuel Gauge Indicators
A total of 9 LED indicators are provided in order to display the state of charge of the battery pack.
The indications are as follows:
9th LED (amber) ...................... Battery Pack is approximately 100% full
8th LED (amber) ...................... Battery Pack is approximately 90% full
7th LED (amber) ...................... Battery Pack is approximately 78% full
6th LED (amber) ...................... Battery Pack is approximately 67% full
5th LED (amber) ...................... Battery Pack is approximately 55% full
4th LED (amber) ...................... Battery Pack is approximately 45% full
3rd LED (red) ........................... Battery Pack is approximately 33% full
2nd LED (red) .......................... Battery Pack is approximately 20% full
1st LED (red) ........................... Battery Pack is approximately 10% full
STANDBY MODE. .................... The appropriate LED will flash every few seconds when the equipment/vehicle is not in use.
SPECIAL NOTE: The LED will stay on when the equipment is in use. When the equipment/vehicle is not being used
the Battery Fuel Gauge will go to STANDBY MODE and it will flash every few seconds. During charge, the indicator
will be Pulse from 1 LED up to the LED that indicates state of charge. This may not always happen when the
charger is initially plugged in, but should pulse once the battery pack is at least 50% charged.
FLASHING 10% led(red) . . . .This LED will blink when the battery pack voltage reaches a very low level (approx. 1.8
volts per cell). ie- on a 48V battery pack the voltage would be 43.20.
*NOTE- On the BFG12V models the Low Voltage LED may begin flashing periodically once the battery falls below
32% and the 4
th
LED is lit. This light will come on more often as the battery is depleted to a lower level.
If the Low Voltage LED comes on often or becomes solid, it is recommended that use of the equipment be stopped
immediately to protect electronics that are connected to the battery pack. Recharge batteries as soon as possible.
TROUBLESHOOTING
PROBLEM: The LED indicator illuminated on the Battery Fuel Gauge is flashing every few seconds.
Solution Sequence:
1. This is the STANDBY MODE and is normal when the equipment/vehicle is not in use. The flashing LED is still indicating
the condition of the battery pack.
2. Start using the equipment/vehicle and the LED light will stay on.
3. If this is happening during charging, wait until the battery pack is at least 50% charged and the appropriate LED will
illuminate and stay on until the charge cycle is complete and then the LED will go to standby mode.
