It replaces OEM part numbers 18LB2035 and 631001122. Voltage, connector, and BMS handshake match the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eL10 and L12 compatibility:\u003c\/strong\u003e\n    Both models run the same 18V rail, share the same battery connector housing, and use the same BMS communication protocol — one battery fits either mower without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through simulated blade-motor inrush at startup. The BMS held through normal start cycles and tripped correctly under sustained over-current, then reset cleanly after the load was removed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before putting the mower away for winter, charge the battery to around 50–60% — not full. A fully charged Li-ion pack sitting unused for several months degrades faster than one stored at partial charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on thick-grass and wet-grass blade load\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe blade motor on the L10 and L12 draws significantly more current through dense or wet grass than it does on a dry, maintained lawn. If the current spike exceeds the BMS threshold — typically triggered in one to two seconds of sustained overload — the pack shuts down to protect the cells. This is not a battery fault; it is the protection circuit doing its job. Let the mower sit for five minutes before restarting, and approach thick patches at a slower walking pace to keep the motor load within BMS limits.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light after the mower sat all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly during storage. After several months in a cold garage, the pack voltage can drop below the charger's acceptance threshold — typically around 12.5V on an 18V pack — causing the charger to show a fault or refuse to start. Some chargers have a recovery or trickle mode; activate it and leave the pack connected for 20–30 minutes. If yours does not, a brief charge from a compatible 18V charger set to recovery mode can bring the cell voltage back above the acceptance threshold, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381279555674,"sku":"BWCS-LML100PW-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381279588442,"sku":"BWCS-LML100PW-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381279621210,"sku":"BWCS-LML100PW-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LML100PW-1.webp?v=1778899919","url":"https:\/\/batteryweb.com\/products\/lawnmaster-l10-replacement-battery-18v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
