It matches the OEM part number JHT-99K-00 and fits both the CM600 and CM-600 variants. The battery slots into the same compartment as the original and connects to the same BMS handshake circuit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCM600 and CM-600 compatibility:\u003c\/strong\u003e\n    Both model designations share the same 14.4V power rail, battery bay dimensions, and BMS communication protocol. The JHT-99K-00 part number covers both. No adapter or wiring change is needed.\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 CM600 platform. The BMS completed its voltage verification handshake, charge current tapered correctly at top of charge, and the device exited standby without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the CM600 complete its full power-on self-test without interrupting it. The device runs a BMS verification routine at startup. Cutting power during that sequence triggers a battery fault flag that stays latched until the next clean 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 CM600 shows a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CM600's BMS stores a learned capacity profile from the previous cell. A fresh replacement starts with no cycle history, so the BMS applies a conservative acceptance threshold on the first charge. The device may flag a fault even when the cell is genuinely at full charge. Run one complete charge-discharge cycle and the BMS recalibrates its threshold to the new cell's actual capacity. After that cycle, the fault clears and the charge indicator reads correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCM600 won't power on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the cell voltage drops below the CM600's BMS recovery threshold — typically around 10V on a 14.4V pack — the BMS locks out discharge entirely as a protection measure. Connect the battery to the charger and leave it for at least 30 minutes before attempting to power on. Most BMS circuits re-enable discharge once the cell climbs above the recovery threshold, usually 12.0V to 12.5V on this pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381447327834,"sku":"BWCS-CMA600MX-1","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381447360602,"sku":"BWCS-CMA600MX-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381447393370,"sku":"BWCS-CMA600MX-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CMA600MX-1.webp?v=1778900875","url":"https:\/\/batteryweb.com\/products\/comen-cm600-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
