It replaces OEM part numbers 01.21.064380 and ID995. These monitors are used in clinical transport and ward settings where continuous vital signs display depends entirely on battery integrity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEPM5, EPM7, EPM8, and SE-1203 compatibility:\u003c\/strong\u003e\n    These models share a common 10.8V three-cell Li-ion architecture with the same physical connector and BMS communication protocol. One cell pack covers all of them without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the EPM5 power-on self-test and monitored BMS handshake response. The charge IC accepted the cell without faulting, and the monitor cleared its battery status flag cleanly after one full charge-discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the monitor complete its full power-on self-test without interruption. The EPM series runs BMS verification at every startup — cutting power during this sequence latches a false battery fault that will persist 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\"\u003eWhy the EPM monitor alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe EPM series BMS stores a charge threshold profile calibrated to the OEM cell's internal resistance signature. A new replacement cell presents a slightly different impedance curve on the first cycle, which the BMS reads as below its pass threshold and triggers the alarm. This is not a cell fault. Run one complete charge-discharge cycle — charge to full, allow normal monitor operation until the low battery warning appears naturally, then recharge fully. After that cycle, the BMS recalibrates its threshold map and the false alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMonitor will not power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 2–3% per month. A battery stored for several months before installation can drop below the EPM's BMS recovery threshold — typically around 9.0V for a 10.8V three-cell pack — which causes the BMS to block output entirely as a protection measure. Connect the battery to the Edan charger and leave it for at least 30 minutes before attempting to power the monitor. Most BMS controllers on this platform include a trickle pre-charge mode that recovers cells down to approximately 8.5V before enabling full charge current.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381368946778,"sku":"BWCS-EDX800MD-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381368979546,"sku":"BWCS-EDX800MD-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381369012314,"sku":"BWCS-EDX800MD-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EDX800MD-1.webp?v=1778900351","url":"https:\/\/batteryweb.com\/products\/edan-epm5-replacement-battery-108v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
