Different battery?

So my battery has been a bit lazy for a while now so I went to change it out at the weekend and was thinking of getting a more powerful larger battery as the car doesn't get used much and it would be good to have the extra charge available.

Off I trot to the local motor factors to reaplce it...
" Can I get the next size up?" I ask. "No, because of it being a japanese car they have taller thinner batteries, this is the biggest you can get, european batteries won't fit" comes the reply....

Now I know some folk on here have upgraded their batteries so how have you got around that problem? (G13BB engine).

There is some electrics that are right up next to the battery which would stop me putting in a wider one, have people moved these?

There are several otions open to you but probably the easiest is to fit a more powerful battery in the same space like this one

This is the one I fitted to my VVT and it works fine.

Alternatively, assuming you don't have abs, its not difficult to make a battery tray to fit on the other side of the engine bay. This is what I have done with my auto and allows a much bigger battery, good if you have a winch. The only thing to watch out for is the height of the battery as obviously you don't want the terminals touching the underside of the bonnet!
I ran a heavy cable back to the original positive connection and joined them with a cut out switch.
I made the battery support from angle and welded it together, and then put some aluminium in the bottom to support the battery. I unbolted the original negative wire and bolted it back on the other side of the vehicle.
Just a couple of ideas!

thanks Obarno thats really helpful.
I'd prefer not to move the battery if I can avoid it but it may be the best option, no ABS by the way.

I'll look into the yellow top batteries too. Thanks.

obarno - do you have a picture as to find out how much room there is as i want to fit one of these in there

mine has 2 batteries . one on drivers side , a tall thin one and one passenger which was fitted for the winch. this is about the same size as our golf so there's bags of room

Rob, if your going to fit two batteries they should always be of the same type, as in simple terms they will always be trying to charge each other, and damage the batteries. What i'm really after is the maximum dimensions of a battery that could fit
