It replaces OEM part numbers 120122 and BATT\/110122. The cell pack restores portable power to the device after the original battery has degraded or failed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBioset 3500 fit:\u003c\/strong\u003e\n    The 3500 platform uses a 9.6V Ni-MH cell pack with a specific connector and BMS handshake. This replacement matches that voltage rail and connector configuration. Swapping to a different voltage or chemistry triggers a permanent battery fault on the device controller.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge-discharge on a medical device load simulator. The BMS accepted the cell chemistry without fault codes, and the charge IC reached full termination voltage without triggering an early cutoff on the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this pack, let the Bioset 3500 run its full power-on self-test without interruption. The device verifies battery state during boot. Cutting power during this sequence sets a false battery fault flag that persists until the next clean full 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 Bioset 3500 may not complete its boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Bioset 3500 runs a BMS verification check at startup that reads cell voltage and internal resistance. A new Ni-MH pack that has not yet been conditioned can show elevated internal resistance, which the boot check may flag as a degraded cell. This is not a fault with the replacement pack — it is the device applying the same threshold it uses to detect worn OEM cells. One full charge-discharge cycle lowers internal resistance to within the boot check's acceptance window. After that first cycle, boot completes normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the Bioset 3500's charge IC applies a conservative current limit to an unrecognised cell pack. This causes the charge cycle to terminate early at the IC's safety threshold rather than at full cell capacity. The display may show 80–90% even after a full charge session. Run one complete discharge-to-cutoff followed by a full recharge — the charge IC recalibrates its termination point to the actual cell capacity on the second cycle, and the indicator reads correctly from that point forward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381496676442,"sku":"BWCS-DBT350MD-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381496709210,"sku":"BWCS-DBT350MD-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381496741978,"sku":"BWCS-DBT350MD-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DBT350MD-1.webp?v=1778901249","url":"https:\/\/batteryweb.com\/products\/bioset-3500-replacement-battery-96v-1700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
