It slots into the HTL10's battery compartment and powers the lock's motor, keypad, and wireless communication module. Capacity figures are taken directly from NABC's product specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHTL10 lock platform:\u003c\/strong\u003e\n    The HTL10 runs its motor drive, keypad backlight, and Bluetooth radio from a single 9V cell. All three draw from the same rail, so the battery must hold stable voltage across both low-draw standby and the brief high-current spike when the motor actuates the deadbolt.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through repeated lock and unlock actuation sequences. The BMS in the HTL10 accepted the battery without fault, and voltage held within spec across motor-start surges at room temperature.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access verification:\u003c\/strong\u003e\n    After fitting a new battery, test every access method — keypad, Bluetooth app, and any keycard or fob — before closing the door. The HTL10 performs a firmware handshake on power restore, and some access methods stay locked out until that sequence completes successfully.\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 new batteries\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HTL10 measures open-circuit voltage at startup to check battery state. A cell that has been sitting in storage can read low enough to trigger the warning even if it is technically new. Remove the battery, wait ten seconds, and reinsert it — this forces a fresh voltage sample. If the warning clears, the cell was just reading a surface-discharge artifact from storage. If the warning persists, verify the cell is seated with correct polarity and that the contacts are clean; the HTL10 threshold sits at approximately 7.2V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth not connecting to the lock after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery cuts power to the HTL10's Bluetooth module, which clears its active pairing session. When power returns, some firmware versions require a manual re-pair before the app reconnects. Open the lock's app, remove the HTL10 from the paired device list, then add it again while standing within one metre of the lock. Once the handshake completes, Bluetooth connectivity restores at full range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360220807258,"sku":"BWCS-DRL250SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360220840026,"sku":"BWCS-DRL250SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360220872794,"sku":"BWCS-DRL250SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRL250SL-1.webp?v=1778610981","url":"https:\/\/batteryweb.com\/products\/nabc-htl10-replacement-battery-9v-2700mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
