Robot lawnmower runs for a very short time (e.g., 10–20 minutes) before needing to recharge.

Safety first: Do not open the battery pack casing. Handle lithium batteries carefully.

• Full charge cycle: Charge the mower until it indicates 100%, then allow it to remain on the station for an extra hour to balance cells.
• Runtime measurement: Time a full mowing run to confirm reduced capacity compared to the original specification.
• Temperature considerations: Avoid operating the mower in near‑freezing temperatures, which reduce effective capacity.
• Replace battery: If runtime remains significantly reduced, install a new Ecovacs‑approved battery pack.

Always recycle old lithium batteries according to local regulations.
