It matches the OEM part number ICR18650-26F and fits the original battery bay without modification. Voltage and capacity align with what the device BMS expects on startup.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompact 2 and Compact 3 platform fit:\u003c\/strong\u003e\n    Both models run the same 11.1V three-cell Li-ion architecture with an identical connector pinout and BMS handshake protocol. One replacement covers both units without any configuration change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the Compact 2 platform. The BMS accepted the cell, completed its verification pass, and held charge within 2% of rated capacity at the end of the first full cycle.\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. Medical Econet devices run a BMS verification sequence at boot — cutting power mid-sequence registers 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 Compact 2 and Compact 3 run a multi-stage power-on self-test that includes a BMS interrogation cycle. A new cell with no prior charge history can return an inconclusive voltage signature during this interrogation, which the device interprets as a fault. This is not a defective battery — it is the BMS applying a conservative threshold against an uncycled cell. Run one full charge-discharge cycle before attempting clinical use, and the BMS will log a confirmed capacity baseline that clears the fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the device's internal BMS compares resting cell voltage against a threshold calibrated to a seasoned OEM cell. A new ICR18650-26F cell holds voltage slightly differently in its first few cycles, and the delta can fall inside the alarm window even at full charge. The fix is one complete charge-discharge cycle run outside clinical duty — this allows the BMS to learn the new cell's voltage curve. After that cycle, the alarm threshold recalibrates and the low-battery warning clears at the correct state of charge. Confirm the resting voltage reads 12.4V or above before returning the device to service.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381443100762,"sku":"BWCS-MEP200MD-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381443133530,"sku":"BWCS-MEP200MD-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381443166298,"sku":"BWCS-MEP200MD-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MEP200MD-1.webp?v=1778900838","url":"https:\/\/batteryweb.com\/products\/medical-econet-compact-2-replacement-battery-111v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
