It fits the portable handheld unit used in prescribed fracture and post-surgical bone healing protocols. Capacity matches the original at 750mAh (2.78Wh) — no modification to the device is required.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExogen Bone Stimulator fit:\u003c\/strong\u003e\n    The Exogen system runs a fixed daily treatment cycle at low continuous draw. This cell matches the original voltage rail and connector, so the BMS handshake completes correctly on power-up without triggering a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Exogen power-on self-test sequence. The BMS accepted the cell, charge acceptance was verified, and the unit completed its boot cycle without a fault flag on first use.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the device run its full power-on self-test without pressing any buttons or interrupting the sequence. The Exogen BMS runs a verification check at startup — interrupting it can set 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\"\u003eWhy the Exogen alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Exogen charge IC applies a conservative acceptance threshold calibrated to the original OEM cell's internal resistance profile. A new replacement cell presents a slightly different impedance signature on the first cycle, which the BMS can read as below its minimum threshold even when the cell is fully charged. This is not a defective battery — it is the BMS learning the new cell's characteristics. Run one complete charge-to-discharge-to-full-charge cycle, and the alarm clears. After that cycle, the unit reads the cell accurately at 3.7V nominal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the cell voltage has dropped below roughly 2.5V, the Exogen BMS enters a protection state and blocks power-on entirely — this is a safety cutoff, not a hardware fault. Connect the device to its charger and leave it for at least 30–60 minutes before attempting to power on. The charge IC uses a low-current pre-charge trickle to recover the cell back above the BMS recovery threshold before switching to full charge rate. Once the indicator shows charging activity, the cell is recovering — do not interrupt it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381411905626,"sku":"BWCS-EBS810MD-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381411938394,"sku":"BWCS-EBS810MD-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381411971162,"sku":"BWCS-EBS810MD-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EBS810MD-1.webp?v=1778900598","url":"https:\/\/batteryweb.com\/products\/exogen-bone-stimulator-replacement-battery-37v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
