It restores wireless vehicle start, door lock, and unlock functions when the original cell has depleted. Dimensions are 41.16 x 29.70 x 5.00mm — verify against your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eClifford 7541X transmitter fit:\u003c\/strong\u003e\n    The 7541X uses a slim Li-Polymer cell at this exact voltage to maintain the low-power RF circuit and rolling code memory. A voltage mismatch here causes the transmitter to appear dead even with a charged cell installed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the bench. The protection circuit tripped correctly at the low-voltage cutoff and accepted charge cleanly from a CC\/CV source at 4.2V termination.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRe-sync after battery swap:\u003c\/strong\u003e\n    Clifford remote start systems lose their link to the control module when the transmitter loses power. After installing this battery, run the 7541X programming sequence — typically holding a button combination near the vehicle — before expecting remote start to respond.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote start not activating after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 7541X control module authenticates the remote via a rolling code handshake. Swapping the battery resets the transmitter's session state, breaking that handshake even if the new cell reads full voltage. The module will ignore commands until the transmitter is re-paired. Clifford's re-sync process requires you to enter programming mode on the control module — consult your 7541X installation guide for the exact button sequence, which ends with the parking lights flashing to confirm pairing.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReduced range immediately after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-Polymer cell ships at storage voltage — typically around 3.6V — not at its full 4.2V charge. At storage voltage, transmit power is slightly lower, which shortens effective range. This is not a fault with the battery or the transmitter. Charge the transmitter fully before use and range will normalise — full charge on a 3.7V Li-Polymer cell reads 4.2V at the terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416113184858,"sku":"BWCS-VPR756SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416113217626,"sku":"BWCS-VPR756SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416113250394,"sku":"BWCS-VPR756SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VPR756SL-1.webp?v=1779760331","url":"https:\/\/batteryweb.com\/products\/clifford-7541x-replacement-battery-37v-600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
