It fits the Assa Abloy EG.086 and EG.090 electronic door locks, as well as the Genie BS Elektronik EK015 access control units. Same voltage, same form factor — 46 x 32 x 10.80mm — as the factory cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEG.086, EG.090, and EK015 compatibility:\u003c\/strong\u003e\n    These models share a common 4.5V battery bay with identical connector orientation and cell geometry. The lock controller draws directly from this flat-cell format — a round or AA stack will not seat correctly, regardless of voltage match.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through lock engagement and disengagement sequences on the EG.086 platform. The controller drew a short current spike on each deadbolt throw; the cell held voltage without sagging below the lock's low-power threshold throughout the test run.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install reconnection window:\u003c\/strong\u003e\n    After swapping the battery, wait 60 seconds before testing the lock remotely. The EG.086 runs a mesh network re-join sequence after any power interruption. Triggering a remote command during that window can register as a fault in the app.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the EG.086 drains faster in high-traffic door scenarios\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eEvery lock cycle — motor engagement, position sensor read, and wireless status push — pulls current from the battery simultaneously. In high-traffic entry points, these cycles compound quickly. The wireless radio in the EG.086 also polls the hub at a set interval; a shorter polling interval burns more power between lock cycles. Check your access control app for the polling or heartbeat setting and extend it if the door is not critical-path.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alert showing immediately after a fresh cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAlkaline cells sitting in storage lose surface charge over time, even unsealed. If the resting voltage drops below 4.2V before installation, the EG.086's controller reads it as a depleted cell and fires the alert immediately. The fix is to confirm the cell reads at or above 4.5V with a multimeter before installing. If it reads low, the cell has been in storage too long — replace it with a fresher unit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416140349530,"sku":"BWCS-ASE015SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416140382298,"sku":"BWCS-ASE015SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416140415066,"sku":"BWCS-ASE015SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ASE015SL_1.webp?v=1779760423","url":"https:\/\/batteryweb.com\/products\/assa-abloy-eg086-replacement-battery-45v-2400mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
