It slots into the lock's battery compartment and powers the access control mechanism — keypad, motor, and wireless module. When the original cell depletes, this is the direct replacement to restore full lock function.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e720553000 lock platform:\u003c\/strong\u003e\n    The 720553000 uses a single 6V alkaline cell to run both the locking motor and the onboard access controller from one voltage rail. Splitting those loads across a lower-voltage cell causes motor stall or communication dropout, so the 6V specification is not interchangeable with standard AA or AAA alkaline packs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through motor-engage cycles and keypad polling events. The BMS held voltage within the lock's acceptable window across repeated actuations without triggering low-battery alerts or mid-cycle cutoffs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access verification:\u003c\/strong\u003e\n    After fitting this battery, test every access method — keypad, Bluetooth, keycard, or app — before closing the door. Some 720553000 firmware builds require a handshake cycle after power interruption that 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\"\u003eLow battery warning on the 720553000 immediately after a fresh cell install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 720553000 checks cell voltage on first power-up and flags anything below its minimum threshold — typically around 5.4V. A cell that has been stored for an extended period can sit at storage voltage rather than full open-circuit voltage, triggering this alert even though the battery is new. Check the cell's open-circuit voltage with a multimeter before installing — a healthy 6V alkaline should read between 6.0V and 6.2V at rest. If it reads below 5.8V, the cell has self-discharged in storage and should be replaced.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLock motor turns slowly or fails to fully retract the bolt after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA slow or incomplete bolt movement on the 720553000 usually means the lock is seeing voltage sag under motor-start load. Alkaline cells can deliver rated open-circuit voltage but still sag below the motor's minimum operating voltage during the high-draw engagement spike. Confirm the battery is seated with correct polarity and that the contact terminals are clean — oxidised contacts add resistance and worsen sag. If the problem persists with a fresh, correctly-spec'd cell, clean the terminal contacts with a dry cotton swab and reseat the battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360219562074,"sku":"BWCS-DRL190SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360219594842,"sku":"BWCS-DRL190SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360219627610,"sku":"BWCS-DRL190SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRL190SL-1.webp?v=1778610981","url":"https:\/\/batteryweb.com\/products\/saft-720553000-replacement-battery-6v-2700mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
