It fits the Monitor Compact 9 and Compact Type 9 configurations. Voltage, connector, and BMS communication protocol match the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMonitor Compact 9 and Compact Type 9 compatibility:\u003c\/strong\u003e\n    Both variants run the same 10.8V three-cell series configuration and use the same BMS handshake over the OEM connector. One cell pack covers both — no hardware modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the Monitor Compact 9 power-on sequence and verified the BMS authenticated correctly, charge IC accepted the cell, and the device completed its startup self-test without a battery fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation power-on sequence:\u003c\/strong\u003e\n    After fitting this battery, let the Monitor Compact 9 complete its full power-on self-test without interruption. Medical device BMS firmware runs a verification cycle at startup — cutting power during that window writes a false battery fault 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\"\u003eWhy the Monitor Compact 9 reports a battery fault on a new, fully charged cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Monitor Compact 9 BMS uses a learned capacity model to validate the attached cell. A new Li-ion pack has not yet completed a full charge-discharge cycle, so the BMS has no reference curve for it. Until the device logs one complete cycle, it may flag the cell as unverified or below threshold. Run one full charge followed by normal device use before placing the unit in clinical rotation — this gives the BMS enough data to accept the new cell without further alerts.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMonitor Compact 9 won't power on after the replacement battery sat unused in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the pack drops below approximately 2.5V per cell (7.5V total), the Monitor Compact 9 BMS enters deep-discharge protection and blocks turn-on to prevent cell damage. Connect the device to mains power and leave it on charge for at least two hours before attempting to power on — the charge IC applies a low-current pre-charge phase to bring cells back above the BMS recovery threshold. Once the charge indicator shows activity, the BMS has cleared the protection state and the device will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381366718554,"sku":"BWCS-BEM7000MD-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381366751322,"sku":"BWCS-BEM7000MD-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381366784090,"sku":"BWCS-BEM7000MD-3","price":97.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BEM7000MD-1.webp?v=1778900266","url":"https:\/\/batteryweb.com\/products\/econet-monitor-compact-9-2110-6001-replacement-battery-108v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
