b77 308 Dead Electrical problem

Hi Anthony,

I think they call the Yellow Tops deep cycle "starting" batteries if I remember correctly. Which would translate to - "I leave my Ferrari sitting for weeks before starting sometimes"....

Yes, the Red Tops seem to be the standard - Hey, I usually start my car every week to two weeks! : )

JRV, why did these cars come equiped with a 66Ah battery (according to the manual) - that seems like a large capacity - it's hard to find a car battery rated at that these days

The Optima I installed in my 308 was a Red Top #75/35, standard cycle, labeled as 'Starting Battery'. Mainly just for starting the car and not much else. I think the cold cranking amps were around 750.

It came with two standard top posts and the new style side terminals to which I installed auxilary cables routed to the forward, upper L/H side of the spare tire enclosure (outer) where I mounted a racing style slip connector and cap. I have a set of commercial grade jumpers with the matching slip connector mounted to one end.

I can jump and /or charge my battery without pulling the washer bottle and the spare, THEN standing on my head!.

I called my battery guy about the Yellow Top battery and he said it was an automotive deep cycle battery for cars and trucks with high amperage appliances like winches or large stereo amps. He said the Marine batteries are Blue Tops.

Hope this helps.

Thanks, DJ.

I did not get a chance to try out my battery - I charged it and it seems to be holding a charge, so I'll put it back in this weekend and try it before purchasing a red top.

Thanks,

Anthony

So far the Red Top has worked fine for me since I removed the winch from the 308.

Check the water in your battery often, especially in the warmer climates. I am told that once the plates are exposed to air and allowed to dry out you loose that area of function.

Good luck! DJ
