Crestron TSR-310-BTP Battery Pack for TSR-310

The TSR-310-BTP is the replacement rechargeable battery for the TSR-310 handheld touch screen remote. It is the same pack the remote ships with, so swapping it restores a tired remote to full runtime instead of replacing a working control surface. The pack sits behind the battery compartment cover on the back of the remote.

Crestron rates the cell at 3.7 volts and 2000 mAh, which is 5.5 hours of continuous use from a charge and about three hours to recharge in a TSR-310-DS or TSR-310-DS-H dock. Keeping a spare on the shelf is the usual approach on a fleet of remotes, since a dead pack takes a room out of service and a replacement is a two minute job.
