How long can a car battery sit unused?
My car’s battery seemed to be on the fritz recently, so I bought a replacement. But my neighbor offered to charge the old one for me, and it’s been working great since. The replacement battery has never been used. I can’t return it, but how long can a car battery sit unused?
- Store the battery upright.
- Keep it in a dry, well-ventilated area.
- Avoid temperature extremes and try to keep the room around 60°F.
- Keep the battery clean.
- Connect the battery to a smart trickle charger or charge the battery every two weeks using a standard charger.
