It carries OEM part number DL-42 and delivers 1200mAh capacity at 7.2Wh. When the existing battery depletes, this unit restores power to the lock's motor, keypad, and access control electronics.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e132 100556 lock fit:\u003c\/strong\u003e\n    This lock draws from a single 6V alkaline cell pack that powers both the motor drive and the microcontroller. The DL-42 form factor matches the battery bay dimensions at 46.00 × 41.50 × 10.50mm, keeping the terminal contacts aligned with the lock's connector plate.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the DL-42 through repeated lock and unlock cycles on the bench. The voltage held steady above 5.4V under motor-start load, which is where ageing or undersized cells typically sag and cause erratic behaviour.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access check:\u003c\/strong\u003e\n    After fitting this battery, test every access method — keypad, Bluetooth, and any keycard or fob — before closing the door. Some 132 100556 units run a firmware handshake on first power-up that must complete before all access credentials 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 not responding after battery swap on the 132 100556\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 132 100556 microcontroller needs a clean power cycle to reinitialise after a battery change. If the lock stays unresponsive, remove the DL-42 battery, wait 30 seconds, then reinsert it firmly until both terminals seat fully. A partial contact on the connector plate is enough to prevent the controller from completing its boot sequence. Once reinitialised, the motor and keypad should respond within five seconds of a valid input.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery warning triggers immediately after fitting a new DL-42\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means the battery is seated with reversed polarity, or the cell voltage is reading below the lock's detection threshold. Alkaline cells from long storage can sit at 5.6V or lower before any load is applied — the 132 100556 firmware flags anything under roughly 5.8V as low battery on startup. Check polarity markings against the bay label, then confirm the battery is fresh stock. A fully charged DL-42 alkaline cell should read 6.0–6.3V open circuit before installation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360197017690,"sku":"BWCS-SDL420SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360197050458,"sku":"BWCS-SDL420SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360197083226,"sku":"BWCS-SDL420SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDL420SL-1.webp?v=1778610959","url":"https:\/\/batteryweb.com\/products\/generic-132-100556-replacement-battery-6v-1200mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
