I live on the panhandle of Florida and a few miles from the beach. I covered my x430 (and garage)with an old car cover and think this is all safe. Question: should I unplug the power supply? Worried about a power surge. The mower is at 90% charge currently.

Hi. My new navimow x430 mower was in the charging station since yesterday. (It docked itself) This morning the battery drained to empty. What could cause the battery to go to zero while in the charging station and not being used. It was at 75% charge when it completed mowing yesterday. Has anyone experienced this? Thanks in advance
