Charging car battery at home

Recommended Posts

I'd like to charge my battery in my garage. For this I have to remove the cables from the positive and negative terminal. I read a description that says  I have to re-teach and set some things after this operation. For example air conditioner, clock, board computer, audio equipment and electric windows. How can I do these operations? Is this a manual about these operations anywhere?

You won’t need to reset anything. It’s absolutely fine to disconnect.

Done it many times on my i40 mate.

although worth noting , with a low battery it’s worth driving with heated rear window and lights ,air con etc ON.

this is because the alternator will only charge battery while under load.

some eco crap reason for that.

OK, thanks!

I was in a battery shop where the expert advised me after a measurement I shouldn't buy a new battery, but I charge the old one for 24 hours. After the charging we will measure the capacity of battery. If the result is bad, hi will order a new battery for me.
