The JM103 is a handheld clinical device used for non-invasive bilirubin screening in neonates. It fits the meter's original battery cavity and connects to the same charge circuit used by the factory cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eJM103 platform fit:\u003c\/strong\u003e\n    The JM103 runs a fixed 2.4V two-cell Ni-MH configuration to power the optical sensor array and display under short, repeated measurement loads. Any replacement must match this voltage rail exactly — mixing chemistries or voltages trips the charge IC and causes persistent fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the JM103's charge circuit and confirmed the BMS accepted the cell without fault codes. The charge IC reached termination correctly and the device completed its power-on self-test on the first boot after installation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the JM103 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this step logs a battery fault that persists until the next clean reboot and can prevent clinical use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the JM103 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe JM103's BMS compares the new cell's discharge curve against a stored OEM reference profile. A fresh Ni-MH cell has not yet established its full electrochemical capacity curve, so the BMS reads the voltage response as below threshold and triggers a low battery flag. This is not a fault with the replacement cell. Run one complete charge-discharge cycle before clinical use — after that cycle, the BMS recalibrates its reference and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eJM103 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 — typically losing 1–2% capacity per day at room temperature. If the cell drops below the JM103's BMS recovery threshold (approximately 2.0V across both cells), the device will not initiate a boot sequence at all. The charge IC may also refuse to begin a charge cycle if it reads the cell as too deeply discharged. Place the battery on a standalone Ni-MH charger first to bring it above 2.2V, then re-install and charge fully in the device before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381488975962,"sku":"BWCS-ASM103MD-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381489008730,"sku":"BWCS-ASM103MD-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381489041498,"sku":"BWCS-ASM103MD-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ASM103MD-1.webp?v=1778901248","url":"https:\/\/batteryweb.com\/products\/minolta-jm103-jaundice-meter-replacement-battery-24v-800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
