Installing a 2nd Battery

Enfield · 14 Mar 2006 at 18:52

Hi there.

I've got brand new battery in my garage which cost me £40 from Halfords. I bought it for my previous car then removed it after it was written off so it's just sitting in my garage doing nothing.

I can't use it on my current car because it has completely different terminals so i'm wondering if I can have a back-up battery. It would be good just in case the primary battery fails for whatever reason.

I'd likely put it in the boot but have no idea what I need to do in order to wire it up?

Any ideas folks? (I'm a complete novice when it comes to the electrical side of things).

Cheers.

Just wire it up in parallel and it will add tot he overall capacity, it will make your car think its only 1 battery.

How do I do that mate?

As said, I know jack about electronics.

Postive of battery 1 goes to positive of battery 2. Negative of battery 1 goes to negative of battery 2.

Woah, it's that easy? :eek:

What type of wire do I need?

Will it put any strain on the alternator?

As I said in the very first post...i'm putting it in the boot.

Shame to waste a good battery. I think the battery the car has at the moment is possibly the original one. It's not going to hurt having two batteries.
