It restores power to the remote control or sensor unit used in Abus alarm installations where the original cell has lost capacity. Dimensions are 62.30 x 49.80 x 5.00mm — verify these against your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTVAC16001 transmitter fit:\u003c\/strong\u003e\n    The TVAC16001 uses a flat Li-Polymer pouch cell on a dedicated charge circuit. The GSP505060 format locks the cell to this board — voltage rail, connector position, and thickness all match the original slot without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the TVAC16001 board. The onboard BMS accepted the cell without fault, held float charge correctly, and the transmitter resumed pairing with the base station after a full charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation charge window:\u003c\/strong\u003e\n    Do not run a zone test immediately after fitting this cell. Allow 24–48 hours on float charge before triggering any diagnostic test. Panels polled before the cell reaches full float will often return a low battery report even on a new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the TVAC16001 panel still shows low battery after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe alarm panel samples battery voltage on a fixed polling cycle. A new Li-Polymer cell straight from storage typically sits below the panel's acceptable float threshold — often under 3.85V — until it completes a supervised charge. The panel logs low battery because that threshold hasn't been met yet, not because the cell is faulty. Leave the system powered for 24–48 hours and the panel will clear the alert once the cell holds above 3.9V at rest.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTVAC16001 transmitter not communicating with base station after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the cell in the TVAC16001 transmitter can drop the pairing state stored in the device's volatile memory. When you refit or replace the cell, the transmitter may power up but fail to re-establish its link with the alarm base station. Re-pair the transmitter using the base station's enrolment mode — the exact button sequence is in the TVAC16001 installation guide, section on device registration. Confirm the link is restored by triggering a supervised test transmission from the transmitter.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309800947802,"sku":"BWCS-ABT161BT-1","price":38.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43309800980570,"sku":"BWCS-ABT161BT-2","price":45.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43309801013338,"sku":"BWCS-ABT161BT-3","price":49.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABT161BT-1.webp?v=1777868106","url":"https:\/\/batteryweb.com\/products\/abus-tvac16001-replacement-battery-37v-2000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
