It slots directly into the mower's battery bay and connects to the onboard BMS via the same multi-pin interface as the factory unit. Capacity is 6800mAh (150.96Wh) — sourced to match the original cell specification, not upsized or downgraded.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e265ACX platform fit:\u003c\/strong\u003e\n    All 265ACX variants share the same 22.2V battery rail, connector pinout, and BMS handshake protocol. That means the same cell pack covers the base model, G2-2, and the 2012 and 2014 production runs without any wiring or firmware difference.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge cycles and simulated blade-motor inrush loads. The BMS held cutoff thresholds within spec, and cell balancing completed correctly across the 6-cell series string on each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSpring recommission tip:\u003c\/strong\u003e\n    Before first use of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells have higher internal resistance, and the blade motor's inrush current can trip the BMS on a cold pack — even if the charge level reads full.\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 or wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Automower 265ACX blade motor draws a short inrush spike every time it bites into dense or wet grass. If the battery's BMS detects that spike as an overcurrent event — common on a worn or ageing pack — it cuts power to protect the cells. A new pack with healthy internal resistance handles the same spike without tripping. If cutouts continue after fitting a new battery, check the blade disc for debris and confirm the cutting height is not set too low for current grass conditions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing fault after the mower sat in storage all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly over several months. If the Automower sat in an unheated garage through winter without a maintenance charge, the pack voltage may have dropped below the charger's acceptance threshold — typically around 18V for a 22.2V 6-cell pack. The charger sees a voltage that looks like a damaged or shorted cell and refuses to initiate a charge cycle. At that point the battery needs replacement; a pack that has sat in deep discharge for weeks has likely suffered permanent cell damage that a charge cycle will not reverse.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381310718042,"sku":"BWCS-HAT266VX-1","price":117.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381310750810,"sku":"BWCS-HAT266VX-2","price":138.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381310783578,"sku":"BWCS-HAT266VX-3","price":154.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HAT266VX-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/husqvarna-automower-265acx-replacement-battery-222v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
