It fits the AG6\/WB, HWAG6S, RESON8, and ADE RESON8 models, among others. It replaces OEM part numbers GP320BVH5A6, GP250BVH5A6, and CP300H.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAG6\/WB and HWAG6S platform fit:\u003c\/strong\u003e\n    These models share the same 6V backup rail, connector pitch, and charge management circuit. A single cell spec covers the whole group — the panel draws trickle charge at the same float voltage across all variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge acceptance and float stabilisation on the AG6\/WB platform. The BMS accepted the cell without fault, held float charge correctly, and cleared the low-battery flag after the conditioning period.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install conditioning on Honeywell panels:\u003c\/strong\u003e\n    Do not trigger a zone test immediately after swapping this cell. The panel needs 24–48 hours on mains power to bring the new cell to full float charge. Running a test before that window closes will almost always trigger a false low-battery warning.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm panel showing low battery hours after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHoneywell AG6\/WB panels check battery voltage against a threshold that assumes a fully conditioned cell. A fresh Ni-MH cell straight from storage sits below that threshold until the panel's trickle charger brings it up to float — typically 6.0–6.5V under load. The panel is not faulty and the new cell is not defective. Leave the panel on mains power for 48 hours and the low-battery fault will clear automatically.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSiren not sounding during a test cycle after backup battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AG6\/WB siren output is tied to backup battery state during self-test. If the panel has flagged the battery as low — even a false flag during the conditioning window — it suppresses the siren trigger as a precaution. This is a firmware-level safety hold, not a wiring fault. Wait until the low-battery fault clears, then rerun the test; the siren should activate normally once the cell reaches full float at approximately 6.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309830275162,"sku":"BWCS-HYP420BT-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309830307930,"sku":"BWCS-HYP420BT-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309830340698,"sku":"BWCS-HYP420BT-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYP420BT-1.webp?v=1777868261","url":"https:\/\/batteryweb.com\/products\/honeywell-ag6wb-replacement-battery-6v-230mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
