Fits the LMO 36-40 and LMO 36-46 cordless push mowers, plus the 36V Leaf Blower LBL 4 and other compatible tools in the same voltage family. One battery pack, multiple tools — that's the point of the shared 36V platform.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared 36V platform compatibility:\u003c\/strong\u003e The LMO 36-40, LMO 36-46, and LBL 4 all draw from the same 36V rail with a common connector and BMS handshake, which is why one pack services all of them.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage steady under mowing load and tripped cleanly at the low-voltage cutoff without triggering a fault state.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a new pack:\u003c\/strong\u003e Run a full charge before first use and let the mower fully discharge at least once — this lets the BMS calibrate its state-of-charge readings accurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy 180Wh matters for a 40cm cutting deck\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LMO 36-40 draws significantly more current in mulching mode than in standard collection mode — the blade speed stays constant but the motor works harder through thick clippings. A 5000mAh pack at 36V gives enough headroom to handle that load without the BMS throttling output early. Thicker or damp grass will draw more current; dry, short grass will draw less.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery shows full charge but mower loses power quickly — here's why\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means the BMS has lost calibration, not that the cells are failing. It reads 100% at rest but can't accurately track discharge under real motor load. The fix is straightforward: charge the pack to full, run the mower until it shuts off on low-voltage cutoff, then charge fully again. One or two full cycles resets the BMS reference points and restores accurate charge reporting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175806304346,"sku":"BWCS-KRF360PW-1","price":130.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175806337114,"sku":"BWCS-KRF360PW-2","price":153.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175806369882,"sku":"BWCS-KRF360PW-3","price":171.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KRF360PW_1.webp?v=1775236276","url":"https:\/\/batteryweb.com\/products\/karcher-cordless-lawn-mower-lmo-36-40-replacement-battery-36v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
