It matches the OEM part numbers BM-S\/B5226 and MS862278. Capacity is 36Wh — identical to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEK10 Elite platform compatibility:\u003c\/strong\u003e\n    The Elite, Elite II 862278, Elite II EKG, and related variants share a common 12V battery bay, connector pinout, and BMS handshake protocol — one cell fits the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the EK10 Elite's charge IC and confirmed the BMS accepted the new cell, logged no fault codes, and held voltage within the expected 13.8–14.4V float range at end of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test handling:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full startup self-test without interruption. The EK10 Elite runs a BMS verification routine at boot — cutting power during this sequence logs a false battery fault that won't clear until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the EK10 Elite reports a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe EK10 Elite's charge IC uses a stored chemistry profile calibrated to the OEM cell's internal resistance baseline. A new replacement cell has slightly different impedance on the first cycle, and the BMS flags this as a threshold mismatch rather than a genuine fault. Running one complete charge-to-discharge cycle lets the BMS learn the new cell's resistance curve. After that single conditioning cycle, the fault clears and the device accepts the battery as within spec.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage — if the battery dropped below approximately 9V, the EK10 Elite's BMS enters a protection lockout and blocks the startup sequence entirely. The fix is a slow pre-charge: connect the charger and leave it untouched for 30–60 minutes before attempting to power on the device. This allows the charge IC to trickle current into the cell until it clears the BMS recovery threshold, typically around 10.5V, at which point normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381506801754,"sku":"BWCS-MEK100MD-1","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381506834522,"sku":"BWCS-MEK100MD-2","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381506867290,"sku":"BWCS-MEK100MD-3","price":108.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MEK100MD-1.webp?v=1778901341","url":"https:\/\/batteryweb.com\/products\/siemens-ek10-elite-replacement-battery-12v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
