It slots into the panel's backup circuit and keeps the alarm system running during mains power failures. OEM part numbers 802316062X and GP220AAH6WMX both cross-reference this cell directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eENA Pro backup rail compatibility:\u003c\/strong\u003e\n    The ENA Pro uses a dedicated Ni-MH backup circuit that charges at a float voltage matched to a 7.2V six-cell pack. Swapping chemistry or voltage here confuses the panel's charge controller and triggers persistent fault codes. This cell matches the original pack's cell count and charge profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the ENA Pro's charge controller and confirmed the BMS accepted the pack without fault codes. Charge current ramped correctly and the panel cleared its battery fault within the expected window after reaching float.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation charge window:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after fitting this cell. Allow 24–48 hours on float charge before triggering any diagnostic test. The panel samples battery voltage under simulated load during tests — a partially charged cell will fail that check and log a false low-battery event.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm panel losing saved programming during a power outage after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ENA Pro writes its zone configuration and user codes to non-volatile memory, but the backup battery still needs to sustain the panel's logic board through the outage. If the new cell hasn't completed its initial conditioning cycle, it may not hold enough charge to carry the panel through even a short mains interruption. The panel then loses volatile state — some firmware versions also partially reset zone assignments. Fit the battery, leave it on mains for a full 48 hours before testing, and confirm the panel reports battery OK before cutting mains power intentionally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePanel reporting low battery within hours of fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a charge-state reporting issue, not a faulty cell. The ENA Pro measures battery voltage at rest and under a brief discharge pulse — a freshly fitted Ni-MH pack hasn't yet reached its stable float voltage, so both readings fall below the panel's pass threshold. The low-battery alert clears once the charge controller has run the cell through at least one full charge cycle. Leave the panel powered on mains for 24–48 hours and the warning should clear without any intervention. If it persists past 48 hours, check the cell connector is fully seated — an intermittent contact reads as a low-voltage condition.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309819887706,"sku":"BWCS-HSA620BT-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309819920474,"sku":"BWCS-HSA620BT-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309819953242,"sku":"BWCS-HSA620BT-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HSA620BT-1.webp?v=1777868235","url":"https:\/\/batteryweb.com\/products\/yale-smarthome-ena-pro-alarm-control-panel-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
