It matches the OEM voltage, connector, and BMS communication protocol so the mower's docking and charge cycle runs normally. Compatible across AM315x, Automower 310, Automower 310 2005, Automower 310 2015, and 37 additional models in this family.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAutomower 310 \/ AM315x platform fit:\u003c\/strong\u003e\n    These models share the same 18.5V battery bay, connector pinout, and BMS handshake logic. The replacement pack carries the same cell count and voltage rail, so the base station charges it without firmware errors or charge-fault codes.\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 the Automower platform. The BMS held cutoff at the correct low-voltage threshold and the base station completed charge without triggering a fault LED on any test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal start-up 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 carry higher internal resistance, and the blade motor's inrush current on a cold pack can trip the BMS before the mower reaches the lawn.\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\"\u003eRobotic mower batteries self-discharge slowly over months of storage. If a pack drops below roughly 2.5V per cell, the base station's charger circuit sees a voltage outside its acceptance window and flags a fault rather than charging. A dedicated Li-ion recovery charger can bring individual cells back above that threshold. Once cells read above 3.0V, the Automower base station will accept the pack and resume normal charging.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMower cuts out mid-row then resumes on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is thermal protection activating, not a faulty battery. Dense or wet grass forces the blade motor to draw sustained high current, which heats the cells faster than the BMS expects under normal lawn conditions. The BMS cuts power to protect the cells, then resets once pack temperature drops. Let the mower sit at the base station for five minutes before restarting — if cutouts continue, check for grass buildup around the blade disc restricting airflow.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381311570010,"sku":"BWCS-HAT315VX-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381311602778,"sku":"BWCS-HAT315VX-2","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381311635546,"sku":"BWCS-HAT315VX-3","price":72.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HAT315VX-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/husqvarna-am315x-replacement-battery-185v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
