It replaces OEM part number B11707. The ActiveCare + S.F.T delivers pneumatic compression therapy for venous insufficiency, post-operative swelling, and lymphatic drainage — and it depends on a stable, correctly profiled battery to complete each therapy cycle without interruption.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eActiveCare + S.F.T platform fit:\u003c\/strong\u003e\n    The B11707 cell pack runs at 7.2V nominal and matches the connector pinout and BMS communication protocol the ActiveCare + S.F.T controller expects. Swapping in a cell at a different voltage rail causes the charge IC to reject the pack outright.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the ActiveCare + S.F.T charge-discharge sequence. The BMS registered correct cell chemistry on handshake, accepted a full charge without flagging a fault, and held load across a complete compression cycle sequence without voltage sag tripping the cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After installing this battery, allow the device to complete its full power-on self-test without interruption. The ActiveCare + S.F.T runs a BMS verification sequence at every boot — cutting power during this window writes a fault flag that persists until the next full reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge after installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ActiveCare + S.F.T charge IC applies a conservative current limit when it first sees a new Ni-MH cell pack. This is intentional — the controller profiles the internal resistance before allowing a full charge acceptance. On the first charge, the indicator may plateau at 85–90% and stop climbing. Run one complete charge-discharge cycle and the controller recalibrates its end-of-charge threshold. After that cycle, the indicator should reach 100% consistently.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice fails self-test and shows a battery fault after a confirmed successful charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS learn cycle has not completed. The ActiveCare + S.F.T sets its self-test pass threshold against stored OEM cell data, and a new replacement pack does not yet have a discharge history logged. The device reads the cell as outside expected parameters and flags it as faulty even though the charge level is correct. The fix is one full charge-discharge cycle before clinical use — after that cycle, the BMS updates its reference data and the self-test passes at 7.2V nominal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381409448026,"sku":"BWCS-MCB117MD-1","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381409480794,"sku":"BWCS-MCB117MD-2","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381409513562,"sku":"BWCS-MCB117MD-3","price":63.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MCB117MD-1.webp?v=1778900598","url":"https:\/\/batteryweb.com\/products\/medical-compression-system-activecare-sft-replacement-battery-72v-2500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
