What battery ?

[johnnybbad]

Hi all, just bought my first surf ( 1991 2.4 ) and have noticed ive got all the wiring / battery box for a second battery.

The one that is on it is quite new, but i would like to put a second battery on the surf.

Do both the the batterys have to be the same cca or does it not matter.

Thanks John

Its probably best if they are, so they are balenced when under load.
