Question: What happens if you mix up jumper cables?

Is it safe to combine jumper cables?

What happens if you connect jumper cables to both terminals?

Does it matter what jumper cables go on first?

A: Both ways work equally well. However, there is the risk of a spark when connecting the cables, and if there is any hydrogen gas leaking from the battery, there may be an explosion.

How long should you drive after jumping a car?

Why do you remove negative terminal first?

Is there a way to fix an overcharged battery?

Instead of using a battery charger, you could opt for a battery maintainer. These maintainers are devices similar to battery chargers, but they operate in a different way. Battery maintainers supply a small amount of electricity to your battery over a longer period.
