It fits the WM15830 and Accuvac Rescue platform. OEM part number WM10647 cross-references directly — no modification required to install.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAccuvac Rescue platform fit:\u003c\/strong\u003e\n    The WM15830 and Accuvac Rescue share the same 12V supply rail, F2X5 connector layout, and BMS handshake protocol. Swapping between compatible models on this platform works without a firmware prompt or charge-cycle reset on the device side.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles through the WM10647 circuit, confirmed the BMS accepted the new cell pack without a fault flag, and verified the charge IC reached termination voltage before the indicator stepped to full.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    The Accuvac Rescue runs a BMS verification sequence at every startup. Do not interrupt this cycle after fitting a new battery — cutting power mid-sequence stores a false battery fault that persists until the next full reboot. Let the self-test complete before use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Accuvac Rescue BMS calibrates its low-battery threshold against charge history, not just terminal voltage. A new cell pack has no history, so the BMS applies a conservative pass threshold at first startup. The alarm clears after one complete charge-to-discharge cycle that lets the BMS log actual capacity data. Run one full cycle before drawing any clinical conclusion about battery state.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day. A cell pack that sat in a warehouse for several months can drop below the Accuvac Rescue's BMS recovery threshold — typically around 9V for a 12V Ni-MH pack — and the device will not boot. Connect the charger and leave it for a full charge cycle without attempting to power on. If the charge indicator does not activate within 30 minutes, check charger output voltage at the connector — it should read between 13.5V and 14.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381390245978,"sku":"BWCS-WM1583MD-1","price":308.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381390278746,"sku":"BWCS-WM1583MD-2","price":368.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381390311514,"sku":"BWCS-WM1583MD-3","price":412.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WM1583MD-1.webp?v=1778900511","url":"https:\/\/batteryweb.com\/products\/weinmann-pump-accuvac-rescue-replacement-battery-12v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
