It fits the 38.4LI, DC-3630LI, Comfort 38.4 Li, and over 80 compatible AL-KO mower models. OEM part numbers covered include 91132807, 113124, 113126, 113280, B150, and B200.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e38.4LI and DC-3630LI platform fit:\u003c\/strong\u003e\n    These models share the same 36V battery rail, connector pinout, and BMS handshake protocol. One pack covers the full range without any adapter or firmware mismatch.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge-discharge cycle on the AL-KO platform and monitored BMS response under simulated blade-motor inrush. Cell voltages balanced correctly and the protection circuit responded within spec on over-current events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    If the mower has sat unused since autumn, bring the battery indoors overnight before the first spring use. Cells below 10°C carry higher internal resistance, and the blade motor's inrush current on a cold pack can trip the BMS before the blades reach full speed.\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-lawn blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AL-KO 38.4LI blade motor draws a sharp inrush current every time it bites into dense or wet grass. If the battery's state of charge is already low, the BMS reads that spike as an over-current event and shuts the pack down to protect the cells. This is normal protection behaviour, not a battery fault. Let the pack cool for five minutes, then resume on a lighter row to confirm the BMS resets cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger won't accept the pack after winter storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells left in a garage over winter can self-discharge below the charger's acceptance threshold — typically around 2.5V per cell. When the pack voltage is too low, the charger reads it as a fault and refuses to start a charge cycle. Some AL-KO chargers include a recovery or \"wake-up\" mode — connect the pack and hold the charge button for 5–10 seconds to initiate a low-current pre-charge. If the charger begins the cycle, allow it to complete fully before using the mower.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381319794778,"sku":"BWCS-ALK384PW-1","price":172.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381319827546,"sku":"BWCS-ALK384PW-2","price":204.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381319860314,"sku":"BWCS-ALK384PW-3","price":228.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ALK384PW-1.webp?v=1778899945","url":"https:\/\/batteryweb.com\/products\/al-ko-384li-replacement-battery-36v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
