The JM103 is a transcutaneous bilirubin meter used for non-invasive newborn jaundice screening in clinical settings. When the original cell degrades, this replacement restores the meter's optical sensor and display to full operating capacity.\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 low-voltage 2.4V Ni-MH cell because the optical sensor and measurement circuit require a stable, regulated supply well below what Li-ion provides. The physical footprint — 45 × 22 × 10mm — must match exactly or the cell will not seat against the contact pads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the JM103's startup sequence and confirmed the BMS accepted the charge profile without triggering a fault state. The protection circuit held cutoff at the expected low-voltage threshold across repeated charge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup procedure:\u003c\/strong\u003e\n    After installing this cell, allow the JM103 to complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup, and cutting power mid-sequence generates a persistent battery fault flag that does not clear 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 JM103 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe JM103's BMS is calibrated to the discharge curve of the original OEM cell. A new replacement cell has a slightly different internal resistance profile in its first few cycles, which the BMS reads as a voltage sag and flags as low charge. This is a chemistry recognition issue, not a defective cell. Run one complete charge-discharge cycle before clinical use and the BMS recalibrates its threshold to match the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eJM103 not powering on after the battery sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–3% per day at room temperature. A cell stored for several months can drop below the JM103's BMS recovery threshold — typically around 1.0V per cell — at which point the device will not respond to the power button. Place the battery in a compatible Ni-MH charger and apply a slow charge at 0.1C for 30–60 minutes to bring the cell voltage above the recovery floor before reinserting it in the meter.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381488681050,"sku":"BWCS-ASM103MD-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381488713818,"sku":"BWCS-ASM103MD-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381488746586,"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\/drager-jm103-jaundice-meter-replacement-battery-24v-800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
