Gloworm 3400mAh 2 cell battery, (no fuel gauge)
This is the battery that comes stock with the Gloworm Alpha. It's identical to the standard high capacity 2 cell battery except it doesn't have the 8 stage fuel gauge. Instead it has a red and green led to show that is charging or fully charge. It relies on the lighted button on the back of the 2018 lights to show the state of charge. Works great for all other bike lights.
8.4V (fully charged)
