It is a direct cell replacement for units where the original pack no longer holds a charge through a full mowing cycle. Voltage and connector match the OEM specification across the listed platform.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model compatibility on the Lawnbott platform:\u003c\/strong\u003e\n    The Lb75 through Lb1500 series share a common 25.2V power rail and the same BMS handshake protocol. That is why a single pack services the full range — the BMS communicates with the dock charger the same way across all listed units.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge-discharge cycles on a Lb1200-class mower dock. The BMS balanced cells correctly across the 6S configuration, and cutoff thresholds for both over-current and low-voltage tripped at expected values with no latching faults.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage prep for robotic mower batteries:\u003c\/strong\u003e\n    Before parking the mower for winter, charge the pack to approximately 60% — not full. A fully charged Li-ion pack sitting unused for months accelerates capacity loss. Most Lawnbott docks will reach this level if you interrupt a charge cycle manually at roughly 15V on the pack terminals.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff during thick-grass or wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe blade motor on the Lb-series draws a sharp inrush current every time it hits dense or wet grass. A new or cold pack has slightly higher internal resistance, and that inrush can push instantaneous current draw past the BMS over-current threshold. The BMS trips as a protection measure — it is not a fault in the battery. Let the mower rest for five minutes, then resume. After the first five to eight charge cycles, cell internal resistance drops and nuisance trips become rare.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows fault light after mower sat idle all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRobotic mower batteries left on the dock — or off it — through winter can discharge below the charger's acceptance voltage threshold, typically around 20V for a 25.2V pack. The dock charger sees the pack as a damaged cell group and refuses to begin a charge cycle. Use a bench charger or a compatible Li-ion charger with a recovery or \"wake-up\" mode to push the pack back above 22V. Once the pack voltage clears that threshold, the standard dock charger will accept it and complete a normal charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381308522586,"sku":"BWCS-ABL120VX-1","price":229.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381308555354,"sku":"BWCS-ABL120VX-2","price":273.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381308588122,"sku":"BWCS-ABL120VX-3","price":305.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABL120VX-1.webp?v=1778899944","url":"https:\/\/batteryweb.com\/products\/lawnbott-lb75-replacement-battery-252v-10200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
