It matches the original voltage rail and connector spec, and crosses to OEM part numbers 4S2P18650-H1008 and NP-1. Capacity figure is taken directly from the product specification — 76.96Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIM15 platform fit:\u003c\/strong\u003e\n    The IM15 runs a 4S2P 18650 cell configuration at 14.8V nominal. This pack matches that cell arrangement, voltage rail, and the BMS handshake the device expects at power-on. Any deviation in cell count or voltage would trigger a battery fault on boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the IM15 power-on self-test sequence and monitored BMS communication. The pack passed the self-test threshold on the second full charge cycle after an initial shallow first charge — consistent with new 18650 cell behaviour on medical-grade BMS logic.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use self-test protocol:\u003c\/strong\u003e\n    After installing this pack, allow the IM15 to complete its full power-on self-test without interruption. The device runs BMS verification at startup — cutting power during this sequence logs 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 IM15 flags a battery fault immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe IM15 BMS compares the incoming pack's charge state against a learned threshold calibrated to the OEM cell chemistry. A new replacement cell has not completed a learn cycle, so the BMS may reject the charge reading even when the charger shows 100%. This is not a fault with the pack — it is the BMS applying a conservative first-use threshold. Run one full charge-to-discharge cycle before clinical deployment. After that cycle, the BMS recalibrates its threshold and the fault clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIM15 will not power on after the battery sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-ion cells self-discharge over time. If this pack sat in storage for several months, cell voltage may have dropped below the IM15 BMS's minimum recovery threshold — typically around 2.5V per cell, or 10V at pack level. Below that threshold the BMS locks out the discharge circuit as a protective measure and the device will not respond at all. Connect the pack to the OEM charger and leave it for a minimum of two hours without interruption — most chargers apply a trickle pre-charge below 3.0V per cell to bring the pack back into the normal charge window before switching to full current.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381467185242,"sku":"BWCS-BCG150MD-1","price":171.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381467218010,"sku":"BWCS-BCG150MD-2","price":200.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381467250778,"sku":"BWCS-BCG150MD-3","price":221.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCG150MD-1.webp?v=1778901052","url":"https:\/\/batteryweb.com\/products\/biocare-im15-replacement-battery-148v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
