no no no no!!! Had soooo many problems with them, had dozens play up, our motor factors has stopped supplying them they are that bad, changed to AC Delco.
And they never replace them under warranty, always have some c**k and bull story that the car has a discharge, or needs an alternator! So they never have to replace them!
You have to send them off if you feel there faulty, and they "test" them on there special equipment.
My 2002 cup battery gave up in 08, i replaced it with a vauxhall one as that was what we kept in stock at the time.
We keep Motrio batteries ( cheaper renault alternative), in stock at the min! No problems with them as of yet.
