What size varta/ other make battery do u fellow 16v'ers use? I got a baby varta 1 which I got a while bk wen the car was a 1.3, now its 2.0 abf. Was fine for months startin the car, until I loaded it up with elec windows, alarm, c/lockin etc, now I think its feelin the strain as 10 mins of radio with ign off flattens it.. What sorta amp battery am I after ideally?? Cheers peeps
