It fits the TPMC-8X, TPMC-8X WiFi, and TPMC-8X-GA WiFi Touch Panel. The TPMC-8X-BTPE is the OEM part number this cell replaces directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTPMC-8X, TPMC-8X WiFi, TPMC-8X-GA compatibility:\u003c\/strong\u003e\n    All three models use the same 7.4V battery rail, connector layout, and BMS handshake protocol. One cell fits all three without firmware or hardware changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the TPMC-8X platform. The BMS accepted the pack without faults, and the panel completed full boot and wireless registration as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install re-seating check:\u003c\/strong\u003e\n    The TPMC-8X battery compartment uses a locking connector that must click fully into place. A partially seated connector causes the panel to report low battery or refuse to power on even with a fully charged cell — press the connector firmly until you hear the latch engage.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the TPMC-8X drops off the network after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAfter installing a new cell, the TPMC-8X sometimes loses its WiFi association and fails to reconnect. This happens because a full power interruption during the swap clears the panel's volatile network state. The fix is to let the panel complete its full boot sequence — typically 60 to 90 seconds — before attempting any control commands. If the panel still shows offline, navigate to the network settings on the touchscreen and re-confirm the IP assignment or DHCP lease.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTPMC-8X touchscreen unresponsive after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the screen powers on but touch input does not register, the panel has likely booted into a calibration fault state triggered by the power gap during battery replacement. This is a known behaviour in Crestron touchpanel firmware when the battery is removed for an extended period. Hold the physical reset pinhole on the rear of the unit for five seconds to force a soft reset. After reboot, the touchscreen re-initialises the digitiser and normal input resumes — no reconfiguration of the control system is required.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416103551066,"sku":"BWCS-CRM09SL-1","price":52.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43416103583834,"sku":"BWCS-CRM09SL-2","price":61.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43416103616602,"sku":"BWCS-CRM09SL-3","price":67.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CRM09SL-1.webp?v=1779760263","url":"https:\/\/batteryweb.com\/products\/crestron-tpmc-8x-replacement-battery-74v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
