2 automatic Modes – Battery charge level monitor (single LED blink mode) & Charging system test (arrow mode).
4 LEDs cover ‘full to empty’ voltage range of all 12V batteries, including higher voltage AGM for power sport (4th √√ LED ≥ 12.7V ).
Battery charge level : LED matching charge level blinks every 5 seconds (long term draw less than 0.2mA).
Vehicle Charge system : LED arrow mode activates when charge voltage reaches minimum 13.5V (√ green LED) or ideal range of 14V+ (√√ green LED).
SAE charge port with weatherproof sealing cap.
