It fits both the Monitor Compact 9 21.10-6001 and Compact Type 9 variants. Cell references include ICR18650 22F-032PpTC and BM7_032PpTC(3ICR19\/65-2).\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 share the same 10.8V three-cell Li-ion configuration, the same physical connector, and the same BMS handshake protocol — so one battery covers both platforms 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 full charge and discharge on the Monitor Compact 9 platform. The BMS completed its cell-balance pass, voltage held steady at 10.8V under load, and the charge IC accepted the cell without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test — do not interrupt:\u003c\/strong\u003e\n    After fitting this battery, let the Monitor Compact 9 complete its full startup sequence without cutting power. The device runs a BMS verification routine at boot. If that sequence is interrupted, the unit logs a false battery fault that clears only after a complete reboot cycle.\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 shows a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Monitor Compact 9 BMS applies a capacity threshold check based on OEM cell chemistry parameters. A new replacement cell has not yet completed a full charge-discharge learn cycle, so the BMS may flag it as non-conforming even when voltage reads correctly at 10.8V. This is not a defective battery — it is the BMS comparing an uncalibrated cell against a stored OEM baseline. Run one complete charge-discharge cycle through the device before treating any fault indicator as a real failure.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Monitor Compact 9 stalls mid-boot after a battery change, the most likely cause is a cell that has self-discharged below the BMS recovery threshold during storage. At voltages below approximately 9.0V, the BMS will not release power to the main board, so the device appears dead rather than low. Connect the battery to the charger for at least 30 minutes before attempting to power on — this brings the cell above the recovery threshold and allows the BMS to initialise normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381366521946,"sku":"BWCS-BEM7000MX-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381366554714,"sku":"BWCS-BEM7000MX-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381366587482,"sku":"BWCS-BEM7000MX-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BEM7000MX-1.webp?v=1778900266","url":"https:\/\/batteryweb.com\/products\/econet-monitor-compact-9-2110-6001-replacement-battery-108v-6700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
