The 6800-12-1 uses this battery to power its locking motor, keypad, and access control logic. When the original battery depletes, the lock stops responding entirely — this replacement restores full operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWinfield 6800-12-1 fit:\u003c\/strong\u003e\n    The 6800-12-1 runs its motor driver and control board from a single 6V cell. A mismatch in voltage or physical dimensions will prevent the battery from seating or cause the BMS to reject the supply rail. This cell matches the 52.30 x 29.00 x 14.70mm form factor and 6V nominal required by the lock housing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through the lock's initialization cycle and confirmed the control board accepted the supply voltage without fault. The motor actuated cleanly across multiple lock and unlock cycles at ambient temperature.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access verification:\u003c\/strong\u003e\n    After fitting this battery, test every access method — keypad, Bluetooth, and any keycards — before closing the door. The 6800-12-1 runs a firmware handshake after power interruption, and some access methods won't activate until that sequence completes. Do not close the door until all methods confirm working.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 6800-12-1 beeps low-battery immediately after a fresh install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 6800-12-1 reads supply voltage the moment power is restored. If the new battery sits at storage voltage — typically 5.8–5.9V rather than the nominal 6V — the lock's threshold check can flag it as low before any load is drawn. This false alarm clears once the battery stabilises under load. If the warning persists beyond two or three actuations, check polarity and confirm the battery is seated flush with both terminals making contact.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLock motor turns slowly or stalls mid-cycle after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA slow or stalling motor usually means the battery is delivering voltage but can't sustain current during the motor-start surge. Alkaline cells that have been in storage for extended periods show internal resistance high enough to cause a voltage sag under the lock's peak draw. The 6800-12-1 motor pulls hard at startup — the supply needs to hold above 5.5V through that spike. Use only fresh, recently manufactured cells and confirm the battery compartment contacts are clean and free of corrosion before closing the housing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360219693146,"sku":"BWCS-DRL190SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360219725914,"sku":"BWCS-DRL190SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360219758682,"sku":"BWCS-DRL190SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRL190SL-1.webp?v=1778610981","url":"https:\/\/batteryweb.com\/products\/winfield-6800-12-1-replacement-battery-6v-2700mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
