It fits smart lock models that run on the 130080 battery pack specification. Dimensions are 67.10 × 36.85 × 19.80mm — verify clearance in the battery compartment before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMUL-T-LOCK smart lock platform:\u003c\/strong\u003e\n    These locks share a common 7.4V two-cell Li-ion architecture with an integrated BMS that communicates charge state to the lock controller. Voltage must stay within the 7.4V nominal range — deviating to a single-cell or alternative voltage pack will trigger a fault on the controller board.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the lock's full draw sequence — motor actuation, Bluetooth radio, and keypad polling. The BMS held cell balance within spec across repeated lock and unlock cycles, and the low-battery threshold fired at the correct voltage before cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation access method check:\u003c\/strong\u003e\n    After fitting this battery, test every access method — keypad PIN, Bluetooth app, and keycard — before closing the door. MUL-T-LOCK controllers run a firmware handshake on first power-up after a battery swap. That process must complete fully 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\"\u003eWhy the MUL-T-LOCK controller faults after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the battery is removed, the lock controller loses its retained state. On reinsertion, the BMS negotiates with the controller over the battery's charge level and cell status before the lock returns to normal operation. If the new battery ships at storage voltage — typically around 3.7V per cell — the controller may flag a low-battery fault even though the pack is functional. A short charge cycle before installation clears this. Aim for a resting voltage of at least 7.2V across the pack before fitting it.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBluetooth app not connecting to the lock after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eBluetooth re-pairing failures after a battery change are a known behaviour on some MUL-T-LOCK smart lock models. The lock's Bluetooth module loses its bonding data when power is fully interrupted. The fix is to open the lock app, remove the lock from your device list, and re-add it as a new device using the lock's pairing mode. Do not attempt this with the door closed — confirm the latch retracts manually before exiting the doorway.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360207044698,"sku":"BWCS-AST130SL-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360207077466,"sku":"BWCS-AST130SL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360207110234,"sku":"BWCS-AST130SL-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AST130SL-1.webp?v=1778610942","url":"https:\/\/batteryweb.com\/products\/assa-abloy-mul-t-lock-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
