It powers the lock motor, keypad, and access control electronics. When the original battery depletes, this unit restores full lock function.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e884952 lock compatibility:\u003c\/strong\u003e\n    The HD Supply 884952 runs its motor driver and access control board from a single 6V alkaline cell. Voltage tolerance on this platform is narrow — substituting a 4.5V or 9V pack will trip the BMS or fail the motor driver entirely.\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 sequences. The BMS held stable across motor-start draw spikes and keypad polling intervals without dropping below the 5.4V cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access verification:\u003c\/strong\u003e\n    After fitting new batteries, test every access method — keypad, Bluetooth app, and any keycard or fob — before closing the door. Some firmware states on the 884952 require a full handshake cycle after power interruption before all credential types are accepted.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLock beeping low-battery warning immediately after a fresh battery install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 884952 reads battery state on first power-up and compares voltage against a factory threshold — typically around 5.6V. Alkaline cells that have sat in warehouse storage can measure below this on initial load even though they are new. If the lock beeps immediately after installation, check polarity first, then confirm the replacement battery is within its rated shelf life. A genuinely fresh cell at full open-circuit voltage should clear the warning within one to two lock cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth not reconnecting to the lock app after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePower interruption during a battery swap clears the lock's active Bluetooth session. The 884952 does not automatically re-advertise to a previously paired phone on every power cycle — it waits for a manual trigger. Open the lock's companion app, force-close and reopen it, then hold the lock's pairing button for three seconds to push it back into discovery mode. Once the app confirms connection, test a remote unlock before relying on Bluetooth access.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360222904410,"sku":"BWCS-DRL120SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360222937178,"sku":"BWCS-DRL120SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360222969946,"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\/hd-supply-884952-replacement-battery-6v-2700mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
