It replaces OEM part numbers 584 82 28-01, 584 85 28-01, 584 85 28-02, 589 58 62-01, and variants. The battery slots into the mower's battery compartment and communicates with the onboard BMS via the standard Automower interface.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAutomower 310 and AM315x series fit:\u003c\/strong\u003e\n    These models share the same 18.5V architecture, connector pinout, and BMS handshake protocol. A battery built to one spec works across the full series without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on an Automower platform, confirmed BMS cell balancing engaged correctly, and verified the protection circuit tripped at the expected cutoff threshold under simulated blade-motor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage start-up tip:\u003c\/strong\u003e\n    Before the first mow of spring, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current can trigger the BMS on a cold pack before the mower takes a single pass.\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 310 blade motor draws a sharp inrush current each time it bites into dense or wet grass. If the pack is partially depleted or cold, that spike can push cell voltage momentarily below the BMS's protection threshold, triggering a cutoff. The mower stops, the BMS resets, and the unit often restarts without any error shown. A fully charged, room-temperature pack handles this load better because the cells maintain voltage above 16V under the surge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing fault light after mower sat in storage all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly in storage. Over a full winter, a pack left in the mower can drop below the charger's minimum acceptance voltage — typically around 12V for an 18.5V pack. The charger's fault light comes on because its safety circuit blocks charging a cell group it reads as dead. To recover the pack, use a compatible Li-ion charger with a \"recovery\" or \"wake\" mode, or apply a brief low-current trickle until cell voltage climbs back above 14V, then switch to normal charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381311209562,"sku":"BWCS-HAT310VX-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381311242330,"sku":"BWCS-HAT310VX-2","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381311275098,"sku":"BWCS-HAT310VX-3","price":61.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HAT310VX-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/husqvarna-am315x-replacement-battery-185v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
