These monitors are used in clinical transport and bedside vital sign assessment. Capacity is rated at 21.6Wh, matching the original power specification for uninterrupted monitoring cycles.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKMS95, KMS850, KMS870, KMS890 compatibility:\u003c\/strong\u003e\n    All four Specia models share the same 12V battery rail, connector footprint, and BMS handshake protocol. A single cell format covers the full range without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on the KMS platform. The BMS accepted the Ni-MH chemistry, completed its verification pass, and registered correct capacity on the monitor's battery status display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the Specia monitor to complete its full power-on self-test without interruption. Medical-grade BMS firmware runs a chemistry verification at startup — cutting power mid-sequence causes a false battery fault flag that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpecia KMS monitor alarming low battery with a freshly charged replacement installed\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Specia KMS BMS uses stored charge-curve data calibrated to the original OEM cell. A new Ni-MH cell has a slightly different internal resistance profile until it completes its first full cycle. The monitor's charge-threshold algorithm reads this mismatch as a marginal state-of-charge, triggering the low-battery alarm even when the cell is fully charged. Run one complete charge-discharge cycle through the device before clinical deployment — the BMS recalibrates its curve, and the alarm clears on the next full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpecia KMS 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 1–2% per day at room temperature. A cell stored for several months can drop below the monitor's BMS recovery threshold — typically around 9V for a 12V Ni-MH pack — at which point the device will not initiate a boot sequence at all. Place the battery on a standalone Ni-MH charger first and bring it to at least 10.8V before reinserting it into the monitor. Once above the recovery threshold, the Specia will boot normally and the onboard charger will complete the cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381468364890,"sku":"BWCS-CBP308MD-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381468397658,"sku":"BWCS-CBP308MD-2","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381468430426,"sku":"BWCS-CBP308MD-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBP308MD_1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/keller-medical-specia-kms95-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
