300 Tdi won't start...just out of the blue!

Ben
The secondary battery is a dual purpose, semi deep cycle specifically to run my fridge i had in the back.
Ran it for 48 hrs non stop set on low to medium most of the time.

Its also wired to the plug next to tow bar to run my camper lights etc when out and about or other portable 12 V devices.

I just think the battery is not very good.
I wasn't happy with it but they wouldn't change it over.
It looks small and you know size matters in all things Land ROver:p:p:p

I agree Frank, I'd much rather just have a top of the range battery that I know won't let me down. The starter that's in there is actually a 600CCA while the secondary one is 525CCA. Took it for another drive last night and it again started with no hassles at all so all is okay for now but I'd still like a replacement because the little window on the top of the battery is black...unless it's a very VERY dark green.

The secondary batter is a Super Charge.

Don't why I said M, D34 yellow is the best bet.

Just out of curiosity now what is actually the difference between the Optima blue D34M and yellow D34? The spec sheets basically say they are exactly the same battery but the blue one looks like it has a couple of extra terminals on the top...is that something just for boats?

I'm going to save my pennies and get one of those one day, sure sounds like a worry free battery!
