It replaces OEM part numbers HYLB-1011, 022-000052-00, JHT-99E-00, 022-000040-00, and JHOTA-99K-00. The Star 5000 series covers three monitor variants — the standard 5000, the 5000C, and the 5000E — all sharing the same battery bay and connector.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStar 5000, 5000C, 5000E, and C20 compatibility:\u003c\/strong\u003e\n    These four monitors share the same 14.8V battery architecture, connector pinout, and BMS handshake protocol. A single cell chemistry and pack configuration covers all four, which is why one replacement part number spans the entire range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on a Star 5000 unit. The BMS accepted the cell without a chemistry fault, and the monitor completed its power-on self-test sequence without flagging a battery error on the second cycle onward.\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 Star 5000 runs a BMS verification routine at startup — cutting power during this sequence causes a false battery fault flag that persists until the next 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 Star 5000 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Star 5000's BMS compares the new cell's internal resistance profile against a threshold calibrated for the OEM cell chemistry. A fresh replacement cell — even at full charge — can read as marginal on the first startup because the BMS has not yet completed a learn cycle on the new pack. The alarm clears after one full charge-discharge cycle, which lets the BMS update its capacity estimate. Run the monitor on battery power until it reaches approximately 20% before recharging — this completes the learn cycle faster than repeated shallow discharges.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stuck below 100% after first charge on a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the Star 5000's charge IC applies a conservative current limit to an unrecognised cell, which can cause the indicator to plateau at 90–95% and stop climbing. This is not a fault — it is the charge controller applying a cautious termination threshold until the BMS completes initial calibration. Disconnect from AC power, allow the monitor to draw the pack down under normal use, then perform a second full charge. After this second cycle, the charge indicator should reach 100% and hold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381468561498,"sku":"BWCS-CMA011MD-1","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381468594266,"sku":"BWCS-CMA011MD-2","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381468627034,"sku":"BWCS-CMA011MD-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CMA011MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/comen-star-5000-replacement-battery-148v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
