The JM103 is a neonatal transcutaneous bilirubinometry device used in clinical settings to assess jaundice in newborns without a blood draw. Voltage and capacity match the original 2HR-4UC specification exactly.\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 uses a fixed 2.4V two-cell Ni-MH configuration tied to the device's charge IC and BMS handshake. Swapping to a different voltage or chemistry trips a permanent fault state that requires a full factory reset to clear.\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 state-of-charge reporting within spec. The charge IC completed a full termination cycle without triggering a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the JM103 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-sequence writes a false battery fault to memory 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\"\u003eLow battery alarm on the JM103 immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe JM103's BMS uses a voltage threshold calibrated to the charge profile of a conditioned Ni-MH cell. A new cell straight from packaging has a resting voltage that sits below this threshold because it has not yet completed a full charge-discharge learn cycle. The device reads this as a low-charge state and triggers the alarm even when the cell is physically full. Run one complete charge-discharge cycle through the JM103 before clinical use — after that cycle, the BMS learns the cell's actual capacity curve and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eJM103 not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day at room temperature. A cell stored for several months can drop below 1.8V total — the floor at which the JM103's BMS will not initiate a boot sequence. The charge IC on the JM103 applies a trickle pre-charge to recover deeply discharged cells, but this phase takes longer than a standard charge. Leave the device on charge for a full uninterrupted cycle before attempting to power on — the cell needs to recover to at least 2.2V before the BMS will release the boot lock.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381488779354,"sku":"BWCS-ASM103MD-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381488812122,"sku":"BWCS-ASM103MD-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381488844890,"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\/air-shields-vickers-jm103-jaundice-meter-replacement-battery-24v-800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
