It matches OEM part number OM11158 and fits the JM102 directly. The JM102 is a neonatal diagnostic device used in clinical settings to measure bilirubin levels in newborns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eJM102 platform fit:\u003c\/strong\u003e\n    The JM102 runs a 4.8V Ni-MH cell stack with a BMS that performs a chemistry-verification handshake at startup. This replacement matches that voltage rail and cell configuration exactly, so the device completes its power-on self-test without a battery fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge while monitoring BMS response. The protection circuit engaged correctly at low-voltage cutoff and accepted a full charge without triggering a fault condition. Capacity measured within spec across the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the JM102 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-cycle causes a false battery fault that persists until the next complete reboot. Do not interrupt startup on the first power-on.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the JM102 rejects a new battery on the first self-test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe JM102 BMS checks cell voltage against a minimum threshold during its startup verification routine. A new Ni-MH cell shipped in storage state often sits at a resting voltage that falls just below that threshold — not because the cell is faulty, but because Ni-MH chemistry self-discharges during transit. The device reads this as a battery fault and blocks operation. Running one full charge cycle before first clinical use resolves this — the cell reaches the voltage level the BMS expects to see.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe JM102 charge IC applies a conservative current limit when it first sees a new cell. This is a calibration behaviour — the charger has no stored capacity data for the new cell and defaults to a cautious ceiling. The indicator may stop at 80–90% on the first charge and report full on subsequent cycles once the charge IC has logged one complete cycle. Let the device complete a full charge-discharge-charge sequence before reading the indicator as clinically accurate. After that first cycle, the displayed charge level reflects actual cell state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381489467482,"sku":"BWCS-ASM102MD-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381489500250,"sku":"BWCS-ASM102MD-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381489533018,"sku":"BWCS-ASM102MD-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ASM102MD-1.webp?v=1778901247","url":"https:\/\/batteryweb.com\/products\/air-shields-vickers-jm102-jaundice-mete-replacement-battery-48v-800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
