It restores wireless operation — remote vehicle starting, door locking, and unlocking — when the original cell has depleted. At 21.50 x 20.25 x 3.56mm, it fits the transmitter housing without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePython 7756P transmitter fit:\u003c\/strong\u003e\n    The 7756P uses a slim Li-Polymer cell at this exact voltage and footprint. Dropping to a lower-capacity cell or mismatched voltage causes the transmitter to under-perform or fail to power up at all.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We confirmed cell output at 3.7V nominal, checked the protection circuit response to over-discharge, and verified stable voltage delivery through repeated button-press cycles simulating active remote use.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRe-sync after swap:\u003c\/strong\u003e\n    Any power interruption to the Python 7756P remote triggers a loss of the rolling code link. After installing this battery, run the full programming sequence with the vehicle's control module — typically standing within range and following the button sequence in the Python installation manual for your system.\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\"\u003eReplacing the transmitter battery breaks power to the remote's memory, which clears the paired rolling code. The Python control module stops accepting commands from an unpaired remote as a security measure — this is expected behaviour, not a fault with the battery. You need to re-enter programming mode on the control module and re-pair the transmitter before remote start will respond. Check your Python 7756P system documentation for the exact button sequence, as it varies by firmware version.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTransmitter range noticeably short right after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell ships at storage voltage — typically 3.6V to 3.65V — not at a full 3.7V charge. At storage voltage, RF output from the transmitter circuit is slightly reduced, which shortens effective range. This is not a defective cell. After a full charge cycle via the vehicle's paired charging path or a compatible charger, output stabilises at 3.7V and range returns to normal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416112988250,"sku":"BWCS-CFD794SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416113021018,"sku":"BWCS-CFD794SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416113053786,"sku":"BWCS-CFD794SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CFD794SL-1.webp?v=1779760313","url":"https:\/\/batteryweb.com\/products\/python-7756p-replacement-battery-37v-85mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
