It slots into the same battery bay and connects to the same BMS handshake circuit as the original pack. Use it to restore cutting cycles on any of the listed mowers after the factory cell capacity has faded.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAlex and L-series platform fit:\u003c\/strong\u003e\n    These models share the same 25.2V seven-cell Li-ion architecture, connector pinout, and BMS communication protocol — which is why a single part number covers all of them. Swapping packs across this family works because the charger and mower firmware negotiate over the same signal lines.\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 an Ambrogio-compatible test rig, confirmed BMS handshake acceptance at the charger port, and verified cell balance across all seven cells under simulated blade-motor inrush load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage before first spring use:\u003c\/strong\u003e\n    If the mower has sat in an unheated garage through winter, bring the battery indoors overnight before charging. Below 10°C, Li-ion internal resistance rises sharply — the blade motor's inrush current can trip the BMS on a cold pack before the mower cuts a single row.\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 light after mower sat in garage all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRobotic mower batteries left unused through winter often self-discharge below the charger's acceptance threshold — typically under 20V for a 25.2V pack. Most Ambrogio chargers refuse to begin a charge cycle when cell voltage falls below this floor as a protection measure. A new AG6208003 replacement pack arrives at a storage charge level well above this threshold, so the charger accepts it immediately. If you have a pack in this state, some Ambrogio chargers support a recovery or \"boost\" mode — check the charger LED sequence in the mower's manual to attempt a slow recovery charge before replacing the pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMower cuts out mid-row in thick or wet grass then restarts itself\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the blade motor hits dense or wet grass, inrush current spikes sharply — enough to cross the BMS over-current threshold and trigger a protection cutoff. The mower stops, the BMS resets within a few seconds, and the unit resumes as if nothing happened. This is the protection circuit doing its job, not a faulty battery. If it happens repeatedly on the same patch, let the mower complete a short cooldown of around five minutes; persistent trips on a new pack in normal grass conditions point to a worn blade that is drawing higher current than it should.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381315338330,"sku":"BWCS-ABL300VX-1","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381315371098,"sku":"BWCS-ABL300VX-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381315403866,"sku":"BWCS-ABL300VX-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABL300VX-1.webp?v=1778899944","url":"https:\/\/batteryweb.com\/products\/ambrogio-alex-replacement-battery-252v-2300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
