It fits the AZSG10000, AZSG10005, AZSG10010, and AZSG10001 control units. When mains power drops, this cell keeps the panel armed and the siren circuit live.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAZSG series compatibility:\u003c\/strong\u003e\n    These panels share the same battery bay geometry, 7.2V supply rail, and charge management circuit across the AZSG10000, AZSG10005, AZSG10010, and AZSG10001. The BMS in each unit expects the same internal resistance profile that Ni-MH chemistry provides at this capacity.\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 cutoff verification on the AZSG platform. The panel's charge controller accepted the battery without fault codes, and the BMS terminated charge cleanly at float voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charging protocol:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after fitting this battery. Leave the panel on mains power for 24–48 hours so the cell reaches full float charge. Testing before that window often triggers a false low-battery report from the panel's charge monitor.\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 programming during a power outage after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel resets to factory defaults during a mains outage, the replacement battery has not yet been fully accepted by the charge circuit. The AZSG series requires the battery to complete a full 48-hour float charge before it can sustain panel memory under load. A partially charged Ni-MH cell drops below the panel's minimum operating voltage almost immediately when mains power fails. Restore mains, leave the panel for 48 hours, then test by pulling the mains lead — the panel should hold all zones and programming without resetting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSiren not sounding during a test after backup battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe siren output on the AZSG panel draws a short high-current burst at activation. A freshly fitted Ni-MH cell has not yet stabilised its internal resistance, so the panel's protection circuit suppresses the siren trigger to avoid a voltage collapse. This is not a wiring fault — it is the panel holding back the siren until the battery can handle the load spike. After 30–60 minutes on mains charge, the cell's internal resistance drops enough for the circuit to allow siren output. Re-run the test at that point and the siren should activate normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309821591642,"sku":"BWCS-ABZ100BT-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309821624410,"sku":"BWCS-ABZ100BT-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309821657178,"sku":"BWCS-ABZ100BT-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABZ100BT-1.webp?v=1777868134","url":"https:\/\/batteryweb.com\/products\/abus-azsg10000-replacement-battery-72v-330mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
