Battery Fuel Gauge

GDI Battery Fuel Gauges are designed to accurately monitor the charge capacity of lead acid batteries. GDI fuel gauges can be used to monitor DC powered equipment such as fork lifts, golf carts, floor care equipment, and any other battery powered equipment. Three battery discharge profiles are standard, plus custom profiles, and a lockout option.

Charge capacity is indicated using a high brightness, 10 segment LED bar graph display from full (right LED segment lit) to empty (bottom LED segment lit). LED Flash Alertâ„¢ flashes the 2nd LED from the left as a warning that the battery has discharged 70%. At 80% discharge, LED Flash Alertâ„¢ flashes the left 2 LEDs to indicate very low capacity is remaining. **Other flash levels and discharge algorithms are available.
