Hi All
I have a 63 convertible and gone through several batteries. The last one I used was a Bosch S4 80Ah, CCA 740A. The car doesn't get used a lot, just on sunny days. If the car sits in the garage for a while (4 weeks) I find that it is hard to start (am thinking of installing an electric fuel pump near the tank). As it's a convertible it is using more power to drive the roof mechanism also. I was wondering if the specification of the battery I'm using is too low due to extra cranking for cold starts and roof operation? Any one have any ideas as I'm about to replace the battery? The car has had a new coil and mechanical fuel pump fitted. TBH, I'm not sure if its a combination of things:
Higher spec battery
Electric fuel pump
Maybe alternator?
Any advice would be much appreciated. By the way I'm in the UK so the batteries available here maybe different to the US.
Many thanks
Will
