Battery Installation and
removal
The BTC is equipped to use (2) 16340 rechargeable
batteries. The batteries are independently changeable,
allowing for hot-swapping. While one of the batteries has
sufficient charge, the other battery port can be opened and
that battery can be replaced without cutting power to the
imager. If both battery ports are open, the imager will shut
down.
NOTE: The BTC is specifically designed to use 3.7v 16340
rechargeable batteries. Non-rechargeable, 3v CR123A
batteries can be used in the BTC, but it is not recommended
as working time, and performance will be reduced,
especially in cold weather.
NOTE: Ensure that the battery cover latches are fully
engaged after closing the battery port lids.
