Frequent question: Can you leave car battery outside?

Is it OK to leave a car battery outside?

An excessively high storage temperature must therefore be avoided. The humidity of the air can also affect the charge level if it condenses on the battery and causes small leakage currents between the positive and negative terminals, which causes faster discharge.

Can you leave a car battery outside in the cold?

Car batteries don’t like the cold. The colder the weather gets, the weaker they are. Even a strong, fully charged battery won’t feel 100% if the temperatures drop enough. And if your battery is only half-charged, it’ll freeze solid at just -10 F.
