It fits the LP20 and Lifepak 20 Defibrillator variants and crosses to OEM part numbers 11141-000068, 14200330, 3200497-000, 3200497-001, B11293, and OM11293. Capacity figures are drawn from the product specification, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLifepak 20 and LP20 compatibility:\u003c\/strong\u003e\n    All LP20 variants share the same 12V battery bay, connector pinout, and BMS handshake protocol. A single cell specification covers every unit in the series without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on an LP20 unit and confirmed the BMS accepted the battery, completed its initialisation sequence, and held voltage within the device's operating window across load transitions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the Lifepak 20 to complete its full power-on self-test without interrupting or powering off the unit. The device BMS runs a chemistry verification at startup — cutting power mid-sequence locks in a false battery fault that will persist until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Lifepak 20 BMS rejects a new cell on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LP20 charge IC applies a conservative acceptance threshold tuned to aged OEM cells. A fresh Ni-MH cell presents a different internal resistance profile than a cycled OEM unit, so the BMS may flag the cell as non-compliant on initial charge. This is a learn-cycle issue, not a defective battery. One complete charge-discharge cycle recalibrates the BMS state-of-health register and clears the flag on subsequent charges.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Lifepak 20 monitors resting voltage against a threshold set during the previous discharge cycle. If the battery sat in storage before installation, self-discharge pulls the resting voltage below that threshold — the device reads the cell as depleted even if the charge indicator showed 100%. Fit the battery, run one full charge cycle inside the device, then allow a full discharge before returning the unit to standby. After that cycle, resting voltage stabilises above the alarm threshold and the warning clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381512208474,"sku":"BWCS-MPD200MD-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381512241242,"sku":"BWCS-MPD200MD-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381512274010,"sku":"BWCS-MPD200MD-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MPD200MD-1.webp?v=1778901340","url":"https:\/\/batteryweb.com\/products\/medtronic-physio-control-lifepak-20-replacement-battery-12v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
