went to start the 4/4 four seater, and guess what battery flat, even though it is on a C TeK trickle charger. so I guess the battery is on its way out. My question is, do I take the plunge and go for an Optima battery or just a regular one? having said that do they manufacture one for the 4/4? Is it worth the extra money, the one that is fitted now is a basic battery and about 4 years old. Also is it worth waiting till spring?

I would be grateful for any advice and comments.
