Replacement Battery for Crestron TSR-302

This 3.7 V lithium-ion cell delivers 1800 mAh capacity and 6.66 Wh energy for the Crestron TSR-302 handheld touch screen remote. It matches the original part number TSR-302-BTP and fits the 64.88 x 37.00 x 11.70 mm cavity. The pack weighs 43.0 g and uses a fully decoded chip that communicates with the device exactly like the factory battery.

Voltage and capacity limits

The single-cell 3.7 V chemistry fixes the operating voltage; the remote cannot accept higher-voltage packs or multi-cell configurations. Capacity is capped at 1800 mAh, so runtime scales directly with the touch screen's draw and cannot be extended by a larger cell without physical modification. The battery includes over-charge, over-discharge, over-voltage and short-circuit protection circuits that interrupt current if limits are exceeded.

Installation notes and common issues

Installation requires opening the remote housing and seating the connector; many users follow online videos and complete the swap in minutes. The most frequent problem is a loosely seated connector, which causes the device to report no battery or to shut down unexpectedly. A new cell reaches full performance after two or three complete charge-discharge cycles, and the supplier cautions against using low-quality third-party chargers.

Questions about this item

Should I pick the 1800mAh or 6.66Wh rating when ordering?

They describe the same cell — 1800mAh at 3.7V equals 6.66Wh — so either figure confirms you are getting the correct replacement.

What does 1800mAh mean for daily use in the TSR-302?

The 1800mAh capacity matches the original Crestron TSR-302-BTP spec, giving comparable run-time between charges for the handheld touch-screen remote.

Does the battery use a standard connector or a proprietary Crestron interface?

It is built to the exact Crestron TSR-302-BTP specifications, including the original connector, so it fits the remote without adapters.
