It slots into the same bay as the original and connects to the same BMS handshake. Voltage and capacity match the OEM spec exactly — no down-rating.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAccuvac Pro and WM 11623 compatibility:\u003c\/strong\u003e\n    Both units share the same 14.4V power rail, connector housing, and BMS communication protocol. One cell pack covers both. No adapter, no wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Accuvac Pro's charge and discharge profile. The BMS handshake completed cleanly, charge termination triggered at the correct voltage ceiling, and the suction motor drew current within the expected load range across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup procedure:\u003c\/strong\u003e\n    After fitting this battery, let the device run its full power-on self-test without interrupting it. The Accuvac Pro's BMS runs a verification sequence at every startup. Cutting power during that window — even briefly — flags a battery fault that sticks until the unit is fully rebooted.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Accuvac Pro charge indicator stalls below 100% on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Accuvac Pro's charge IC applies a conservative current limit on the first charge of an unfamiliar cell. It reads internal resistance slightly higher than the settled OEM value and throttles the final absorption phase. The indicator can sit at 90–95% for an extended period before topping off. This resolves after one complete charge-discharge cycle, once the BMS has logged baseline cell behaviour. Do not pull the battery before the first cycle finishes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAccuvac Pro alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe low-battery alarm threshold on the Accuvac Pro is tied to BMS-stored chemistry parameters calibrated to the OEM cell. A new replacement cell that has not completed a full charge-discharge learn cycle can report a state-of-charge value that triggers the alarm even when actual capacity is adequate. The BMS is not yet confident in the new cell's discharge curve. Run one full charge-to-depletion cycle outside clinical use — this allows the BMS to update its reference values and the alarm will stop triggering on a full pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381433532506,"sku":"BWCS-WM1163MD-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381433565274,"sku":"BWCS-WM1163MD-2","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381433598042,"sku":"BWCS-WM1163MD-3","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WM1163MD-1.webp?v=1778900788","url":"https:\/\/batteryweb.com\/products\/weinmann-accuvac-pro-replacement-battery-144v-6000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
