I need a new battery for my 54 plate WRX as it will only last a few days if undriven; but I'm not sure what type to go for, how many amps, etc. I've been told to pay a bit more and go for a heavy duty one, but I had a look in the shop and they range from about 200-500 amps. I don't want to go for the higher amp ones and connect it, only to blow all the fuses. What sort of battery do I need? Any advice would be appreciated.

To Mr 3rd Dec.

If your car only lasts a few days without running flat then there is a problem with your car. Getting a bigger battery is surely only masking the problem and you would be better getting the root cause diagnosed.

Anyone (scooby owner) got some useful info on reliability?

Oh yes that would be just masking it if it was some other problem, but this was soley the old battery causing the problem, the new one is great, I was just unsure as to what one to get. As for reliability, my WRX has been perfect apart from the flat battery. a lot of people like to do an oil change between services, about every 5000 miles, I just ran some slick 50 fuel system cleaner through mine at 35,000 miles, it does seem to have restored some lost power, my commute home from work is one big traffic jam every day, it probably got a bit coked up.

Why do you drive an impreza for your comute home then? Surely it would be more sensible to drive something low powered or even a diesel if you are always in traffic.

I'm not paying to own 2 cars, and I don't want to drive around in a small diesel all the time.

I've got to say after owning a WRX for a while now the brakes really could be better, after a few long hard stops approaching roundabouts or lights they can fade quite a lot, gets a little worrying.
