It powers the locking mechanism — motor, keypad, and wireless module — from a single pack. Drop in when the original depletes and access control stops responding.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHTL11 platform compatibility:\u003c\/strong\u003e\n    Locks using this part number run a 6V bus to drive the motor actuator and maintain the control board. Any replacement must match that voltage exactly — under-voltage causes slow motor response or no actuation at all.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through repeated lock and unlock actuations. The motor drew consistent current on each cycle with no voltage sag below threshold during the stroke.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access method check:\u003c\/strong\u003e\n    After fitting new batteries, test every access method — keypad, Bluetooth, and keycard — before closing the door. Some locks run a firmware handshake after power interruption. If that sequence doesn't complete, certain access methods stay locked out until it does.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy electronic door locks lose response after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCutting power to an electronic lock resets the control board. Some locks won't accept commands from the keypad or wireless module until the board completes its startup sequence, which can take 15–30 seconds. If you reinsert batteries and immediately test the lock, it may appear dead when it's still initialising. Give it a full 30 seconds, then test again before assuming a fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery warning lights up immediately after fitting new batteries\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means polarity is reversed on one or more cells in the pack, or the lock's voltage sensor is reading below its threshold. Check that the positive terminal of the battery pack aligns with the positive marking in the battery compartment. If polarity is correct, the lock's internal voltage divider may be sampling before the alkaline chemistry stabilises — remove the battery, wait 10 seconds, and reinsert. The warning should clear once the board reads a steady 6V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360222052442,"sku":"BWCS-DRL120SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360222085210,"sku":"BWCS-DRL120SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360222117978,"sku":"BWCS-DRL120SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRL120SL-1.webp?v=1778610981","url":"https:\/\/batteryweb.com\/products\/nabc-replacement-battery-6v-2700mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
