It replaces part number 132-512886, restoring power to the lock's keyless entry and motorised latch mechanisms. Fit model is the ILCO 79 Lock series only — confirm your part number before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eILCO 79 Lock series fit:\u003c\/strong\u003e\n    The 79 Lock platform uses a dedicated 2.4V Ni-MH pack rather than standard AA cells. That voltage rail matches the lock's control board and motor driver directly. A mismatched voltage causes the BMS to reject the pack or trip the undervoltage cutoff at startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the ILCO 79 lock's full power-on sequence and confirmed the BMS handshake completed without fault codes. The motor-start current draw at latch engagement stayed within spec across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install access method check:\u003c\/strong\u003e\n    After fitting this pack, test every access method — keypad, key card, and any app-based entry — before closing the door. The ILCO 79 requires a firmware handshake to complete after power is restored, and the lock may not accept all access methods until that sequence finishes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ILCO 79 Lock motor stalls or grinds after a battery replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs leave the factory in a partial state of charge — typically 30–50% capacity. The ILCO 79's latch motor draws a sharp current spike at the moment of engagement, and a partially charged pack can sag below the BMS cutoff threshold during that spike. The lock then faults out mid-cycle, which sounds like a stall or grind. Run a full charge before the first use to bring the pack to its rated 2.4V so the motor-start surge doesn't trip the cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery warning showing immediately after fitting a new 132-512886 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the lock's control board reads open-circuit voltage instead of load voltage at startup — a Ni-MH pack that hasn't been charged will measure below the lock's low-battery threshold even though the pack itself is fine. It's not a faulty battery; it's a capacity issue at first install. Charge the pack fully before fitting it, and the warning clears. If the warning persists after a full charge cycle, check that the pack is seated correctly and the contacts are making clean contact — resting voltage on a fully charged 2.4V Ni-MH pack should read approximately 2.5–2.6V at the terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360216023130,"sku":"BWCS-ILC790SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360216055898,"sku":"BWCS-ILC790SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360216088666,"sku":"BWCS-ILC790SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ILC790SL-1.webp?v=1778611022","url":"https:\/\/batteryweb.com\/products\/ilco-79-lock-replacement-battery-24v-2700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
