It fits the BM3, BM3Plus, BM3Vet, and BM3VetPlus models manufactured from December 2005 through early 2008, covering serial ranges D1F1200001 through D1I03xxxxx and D2F1200001 through D2H02xxxxx. OEM part numbers BM-BAT-3, GP220AAH10BMXZ, and GPRHC222N000 all cross-reference to this cell pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBM3 platform compatibility:\u003c\/strong\u003e\n    The BM3, BM3Plus, BM3Vet, and BM3VetPlus share the same 12V battery rail, connector pinout, and BMS handshake across this production window. One cell pack covers all four variants within the listed serial ranges.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a BM3-class monitor. The BMS accepted the cell chemistry without fault codes, completed the charge handshake, and held voltage within the expected band across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle BMS verification on medical monitors:\u003c\/strong\u003e\n    After fitting this battery, allow the BM3 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at boot — cutting power during this step logs a false battery fault that persists until the next complete reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBM3 monitor not completing boot sequence after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BM3 runs an internal self-test at startup that includes a battery state check. A freshly installed Ni-MH cell starts at a resting voltage that the BMS may flag as marginal if the pack has not yet been through one full charge cycle. The monitor interprets this as a battery fault and halts the boot sequence before reaching the main monitoring screen. Charge the replacement pack fully before the first installation — the BM3's charge IC targets 14.4V for a 12V Ni-MH pack at end-of-charge — then reinstall and power on.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BM3's BMS uses stored capacity thresholds calibrated to an aged OEM cell profile. A new cell presents a slightly different internal resistance signature, and the BMS can misread this as low state-of-charge even when the pack is full. This alarm clears after one complete charge-discharge cycle, which allows the BMS to recalibrate its reference points against the new cell's actual impedance. Run one full cycle — charge to termination, then allow the monitor to discharge under normal operation to the low-battery cutoff — before placing the unit in clinical service.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381366423642,"sku":"BWCS-BEM310MD-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381366456410,"sku":"BWCS-BEM310MD-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381366489178,"sku":"BWCS-BEM310MD-3","price":97.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BEM310MD-1.webp?v=1778900266","url":"https:\/\/batteryweb.com\/products\/bionet-bm3d1f1200001-d1g03xxxxx122005-032006-replacement-battery-12v-2200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
