Verify battery model and charger input

Confirm your instrument uses one of the listed BT-60Q to BT-66Q or GMS-2 battery types before ordering. Ensure a 5 V 2 A USB wall adapter, car charger or computer port is available to power the charger’s micro-USB input.

Three-bay charger frees field outlets

The charger fills three batteries simultaneously at 8.4 V 0.5 A per bay and shows individual status on its LCD panel. This reduces the number of wall sockets or vehicle ports needed during extended survey sessions.
