It replaces OEM part numbers 12-100-0002 and LB-03. Capacity is 6.29Wh — use that figure, not the web-listed spec, when comparing cells.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM800 and LB-03 platform fit:\u003c\/strong\u003e\n    Both the M800 and LB-03 share the same single-cell 3.7V architecture, connector pinout, and BMS communication protocol — which is why one cell covers both. The BMS on these units handshakes with the battery at startup to confirm chemistry and charge state before allowing operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the M800 startup sequence and confirmed the BMS completed its initialization pass without triggering a fault. Charge acceptance across the first three cycles matched OEM charge curve parameters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStartup self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, let the M800 complete its full power-on self-test without interruption. The BMS runs a voltage and chemistry verification at boot — cutting power mid-sequence leaves a fault flag that persists until the next clean reboot, not because the battery is faulty.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the M800 alarms low battery with a freshly charged replacement installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe M800 BMS uses a charge threshold calibrated to the OEM cell's internal resistance profile. A new replacement cell has a slightly different impedance signature until it completes one full charge-discharge cycle. Until that cycle runs, the BMS may read the state-of-charge conservatively and trigger a low-battery alarm even when the cell is at or near 4.2V. Run one complete charge cycle before clinical use to let the BMS recalibrate its threshold against the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice 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 during storage. If the replacement cell drops below approximately 3.0V, the M800 BMS treats it as a deep-discharged or damaged cell and blocks startup as a protection measure. Place the battery on charge for at least 30 minutes before attempting to power on — this brings the cell above the BMS recovery threshold. Once the device powers on successfully, allow a full charge cycle to complete before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381479342170,"sku":"BWCS-BLM800MD-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381479374938,"sku":"BWCS-BLM800MD-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381479407706,"sku":"BWCS-BLM800MD-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLM800MD-1.webp?v=1778901170","url":"https:\/\/batteryweb.com\/products\/bolate-m800-replacement-battery-37v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
