It matches the OEM part number AG6208003 and slots into the same bay as the original pack. Voltage and capacity are matched to the mower's autonomous drive and blade motor system.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAlex, L30, and L50 platform compatibility:\u003c\/strong\u003e\n    These models share the same 25.2V battery architecture, connector format, and BMS handshake protocol. A single cell configuration covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through blade motor start loads and drive system draws. The BMS held cutoff thresholds correctly at both peak inrush and sustained mowing current without false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before the first spring mow, bring the battery indoors overnight if temperatures have been below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current on a cold pack can trip the BMS at startup — even if the battery reads a healthy charge level.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing fault after the mower sat unused all winter\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRobotic mowers often go months without use between autumn and spring. Over that period, a Li-ion pack in storage will self-discharge. If it drops below roughly 2.5V per cell, the charger's acceptance circuit sees the pack as faulty and refuses to begin a charge cycle. This is a BMS protection response, not charger failure. Some Ambrogio chargers have a recovery or wake mode — consult your charger manual for the activation step. If the pack has held above 2.5V per cell, a successful charge cycle will begin normally within a few minutes of connection.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMower cutting out mid-row in thick or wet grass then restarting itself\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHeavy blade load — thick growth or wet conditions — draws higher current than the mower sees on a normal dry lawn. When that current spikes past the BMS threshold, the pack shuts output to protect the cells. The mower stops, the BMS resets after a short pause, and the unit restarts. This is not a faulty battery. Let the mower sit for five minutes before resuming, and check that the blade is clean and sharp — a dull or clogged blade pulls significantly more current per cut.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381307637850,"sku":"BWCS-ABL310VX-1","price":162.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381307670618,"sku":"BWCS-ABL310VX-2","price":192.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381307703386,"sku":"BWCS-ABL310VX-3","price":215.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABL310VX-1.webp?v=1778899944","url":"https:\/\/batteryweb.com\/products\/ambrogio-alex-replacement-battery-252v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
