InfiRay IBC-2 Battery Charger for IBP-2/AC38 Batteries
Compatible with:
Infiray Finder V2
CABIN CBL19 384x288 Thermal Monocular
CABIN CBL25 384x288 Thermal Monocular
Chargers like this usually show an indicator while charging, so check the IBC-2's instructions for what its light means. The surest check is in the field: put the battery back in your Finder V2 or CABIN monocular and look at the battery icon on the display to confirm it took a full charge.
With rechargeable optic batteries, skip the revival tricks. A pack that sat fully drained for months may be damaged, and forcing it can be unsafe. Try a normal charge on the IBC-2 first; if the battery still won't hold a charge, replace it with a new IBP-2 or AC38.
