The original battery on my STi IV was just about dead this morning, and after a bump start it got me to work. I checked it at lunchtime and it would not start the car.

Assuming I'll be replacing it tomorrow, are there any particular recommendations/requirements?

Cheers

 

can not go wrong with subaru battery they are made by verta but from a dealer you are looking at around £71.00 +vat

 

Check your local car shop. Got one this year for 50.00.
Not a lot of point in paying more as this was guaranteed for 3yrs.
