It matches OEM part numbers 586 57 62-02 and 589 58 61-01. Slide it into the bay and the mower's charging station recognises the pack exactly as it does the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAutomower 105, 305, and 308 fitment:\u003c\/strong\u003e\n    These three models share the same 18.5V battery bay, connector pinout, and BMS handshake protocol — one pack covers all three platforms 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 the Automower charging station and confirmed the BMS completed a full charge sequence, balanced cells correctly, and communicated state-of-charge data to the docking station without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage 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.\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 in the garage all winter\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-ion cells self-discharge at roughly 2–3% per month in storage. A pack left in the mower through winter can drop below the charger's minimum acceptance voltage — typically around 14–15V for an 18.5V pack — and the station raises a fault rather than attempting a charge. This is a voltage threshold check built into the charging station's firmware, not a charger fault. If the original battery will not recover, a replacement pack at nominal voltage will allow the station to accept the charge cycle immediately and resume normal scheduling.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMower cuts out mid-row then restarts a few minutes later\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is the battery's thermal protection circuit responding to sustained high current draw — most often triggered when the blade motor works through wet grass or a dense patch that demands more current than the BMS allows continuously. The BMS trips the output, the mower stops, and once the pack temperature drops the circuit resets. Let the mower sit for at least five minutes on open ground before restarting. If it happens repeatedly in normal grass conditions, check that the blade is sharp — a dull blade multiplies motor load significantly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381309669466,"sku":"BWCS-HAT308VX-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381309702234,"sku":"BWCS-HAT308VX-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381309735002,"sku":"BWCS-HAT308VX-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HAT308VX-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/husqvarna-automower-105-replacement-battery-185v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
