18 months without a charge! Battery impact?

[NorthernDStarr]

My elderly neighbor has a 2020 4S. He hasn’t driven the car in months, maybe 16-18 months. And the car has mostly sat idle prior to that. Guessing driven only 1k miles over 3+ years.

I assume this is bad for a battery. Thoughts?

Sure he is still alive?

Depends what charge level was left in the HV battery. If high then not so good but if low then likely better. The owners manual does offer some guidance.

The 12v battery might be a different story and may require a health check.

Consult a dealer.
