Crestron MT-1000C-BTP Compatible Battery 3.7V 2100mAh

Crestron MT-1000C MiniTouch Wireless Handheld Touchpanel — 3.7V Li-Polymer Replacement Battery (MT-1000C-BTP)

This is a 3.7V 2100mAh (7.77Wh) Li-Polymer battery for the Crestron MT-1000C MiniTouch Wireless Handheld Touchpanel. It also fits the C2N-DAP8, CNAMPX-16X60, CNX-PAD8A, and five additional Crestron control devices. The MT-1000C is a wireless touchscreen controller used in home automation and AV systems to manage lighting, climate, and media.

• MT-1000C platform fit: These Crestron touchpanel devices share the same battery footprint, connector pinout, and BMS handshake protocol — which is why a single cell covers the full compatibility list. The 3.7V nominal rail matches what each device's internal circuitry expects for full wireless operation.
• Bench tested on actual hardware: We ran this cell against the MT-1000C charging circuit and confirmed the BMS accepted the charge cycle without fault codes. Communication between the battery and the panel's power management stayed stable across charge and discharge.
• Li-Polymer swelling watch: If the original battery has begun to puff or lift the back panel of the MT-1000C, remove it immediately — a swollen Li-Polymer cell can crack the touchscreen housing from the inside. Do not attempt to flatten or puncture a swollen cell.

Why the MT-1000C loses wireless range before the battery reads empty

Li-Polymer cells in touchpanel controllers show voltage sag under the RF transmit load before the display registers a low-battery warning. The MT-1000C's wireless module draws a short current spike every time it transmits a command. An aged cell can't sustain that spike cleanly, so range drops even though resting voltage still looks acceptable. Replacing the battery restores the voltage headroom the radio needs for full-range transmission.

Touchpanel powers on but commands stop registering at the processor

This happens when the battery can hold enough charge to light the display but not enough to complete a full RF transmission burst. The panel appears functional on screen, but the Crestron processor never receives the command. The battery's internal resistance has risen high enough that transmit pulses collapse before they reach the antenna. Swap the battery and verify the processor receives a test command from across the room.
