It matches the OEM voltage rail, connector, and BMS communication profile required by this equipment class. Capacity figures are taken directly from product data — not estimated from web sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCC26 \/ MC26 platform fit:\u003c\/strong\u003e\n    These models share a common 11.1V three-cell architecture and the same BMS handshake protocol. A battery mismatched on cell chemistry or internal resistance will fail the device's startup verification check, even if it physically connects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the CC26 platform and confirmed the BMS accepted the cell, completed its initialisation sequence, and held voltage within spec under a simulated clinical load profile across the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the device to complete its full power-on self-test cycle without interrupting it. Medical devices in this class run BMS verification at startup — cutting power mid-sequence triggers a false battery fault that persists until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CC26 and MC26 run a BMS learn cycle during their first few boot sequences after a new cell is installed. If the device stalls or loops at the boot screen, the BMS has not yet established a baseline for the new cell's internal resistance. This is not a faulty battery — it is the device's charge IC applying conservative thresholds until it recognises the cell profile. Run one complete charge-discharge cycle, then reboot. The boot sequence should complete normally once the BMS has logged a full cycle.\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\"\u003eThis happens when the device's BMS compares the new cell's voltage curve against the threshold calibrated for a conditioned OEM cell. A fresh replacement cell has not yet settled its internal chemistry, so its resting voltage after a first charge can read slightly below the alarm threshold. The alarm clears after one complete charge-discharge cycle, which lets the BMS recalibrate to the new cell. Charge the battery to full, run the device through a normal use session until it signals low, then charge again — the alarm should not repeat after that second full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381374156890,"sku":"BWCS-AMC260MD-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381374189658,"sku":"BWCS-AMC260MD-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381374222426,"sku":"BWCS-AMC260MD-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AMC260MD-1.webp?v=1778900433","url":"https:\/\/batteryweb.com\/products\/atoms-cc26-replacement-battery-111v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
