It fits the Kaba Ilco 700 series electronic door locks, along with the BL09, IL22, and MLKBA0603 models. These locks run on a single 9V cell that powers the motor, keypad, and access control logic.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e700 \/ BL09 \/ IL22 \/ MLKBA0603 platform:\u003c\/strong\u003e\n    All four models share the same 9V battery bay and draw from a single-cell configuration. The lock controller, motor driver, and keypad backlight run off one voltage rail — which is why the OEM spec is identical across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through motor actuation and keypad polling sequences. The BMS in the lock registered full charge on insertion, and the low-battery indicator did not trip at rest voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap access verification:\u003c\/strong\u003e\n    After fitting a new battery, test the keypad, Bluetooth, and any keycards before closing the door. Some Kaba Ilco models run a firmware handshake after a power interruption — if that sequence hasn't completed, certain access methods will be blocked until it does.\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 700 series immediately after a fresh swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Kaba Ilco 700 samples battery voltage during motor actuation — the highest-draw moment in the cycle. If the battery's internal resistance is too high, voltage sags under that load and the controller interprets it as a depleted cell. Alkaline cells that have been sitting in storage for over a year lose capacity and can't hold voltage under motor-start current. Always check the expiry date printed on the cell before fitting it. A fresh cell at or near its manufacture date should read 9.5V or above off-load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLock motor sluggish or failing to fully retract the bolt\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA slow bolt retraction usually means the battery can't sustain current through the full motor stroke. This happens when a cell is partially discharged or when the lock mechanism has increased friction from wear or temperature. The controller may also cut the motor drive early if voltage drops below its protection threshold mid-cycle. Fit a fresh 9V cell and test the bolt five times in succession — if the fifth retraction is visibly slower than the first, the lock mechanism itself needs inspection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360228376666,"sku":"BWCS-DRL160SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360228409434,"sku":"BWCS-DRL160SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360228442202,"sku":"BWCS-DRL160SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRL160SL-1.webp?v=1778610981","url":"https:\/\/batteryweb.com\/products\/kaba-ilco-700-replacement-battery-9v-2700mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
