Not sure, i think 75ah and over 700cca, when the guy put his meter thingy on them it read 1135cca:eek:. Got them from Pirahna, $100 cheaper than anywhere and they are made by Excide. Next time your over we could swap em in and see how they go:)

Thanks Justin, I find my 4BD1 happy to crank of 1 maggoted rocket battery and a half charged one ok, I always carry leads aswell, the winching isn;t as severe as it used to be, now we're all a bit mellower(read: girly:angel:) so not as big an issue as keeping the beer cold and the music happening:DQuote:

Yeah Ive had them but not because Ive gone out and bought them they've come in vehicles I've purchased or have been in when on trips. (the military also had a bit of a flirt with them and some vehicles that I cant tell you about use the optima range)
for what I do they dont offer the bang for the buck to justify buying new ones when I can get 3 maybe 4 normal batteries for the price of one of the top of the line optimas. I run a dual battery system so I get a cranking battery and deep cycle and not a compromise between the 2.
they have their Advantages, if you can get them cheaply enough then they are IMHO better than just a stock Cranker but I dont think they are better than a deep cycle for doing deep cycle work. If you're budget isnt as big a problem as mine then you can do worse than setting up a dual battery system with 2 optimas.
We have about five or six in various vehicles on our farm .The oldest is in a vineyard tractor (narrow) you have to take the rear wheel off to get to the battery -so i wanted a pretty good battery -the local auto elec guy here ( who is a good guy) recomended them -although he explained how to look after them -automatic charger etc -charge every so often -that battery is over eight years old !- the best part is no maintenance
Well, of all batteries I have had in any of my vehicles, the Optima had the shortest life span :(:( and the highest price tag :mad::mad:. Figure it out...
Well I have had twin Optima yellow tops in my 110 for last 3-4 years. They are now cream crackered. Am going to replace them with a couple of Odyssey batteries.
The stories that I hear in the UK are that Optimas used to be the best batteries around. Due to increased production requirements a factory change occurred and that quality decreased. Expected life span in the UK is now 3-4 years which is relatively short.
Odysseys now have a higher rep in the UK then the Optimas.
Batteries are a developing/changing market so what might be the best battery now may well not be the best in a couple of years time.
Hope that helps

I've been running 2 yellow tops since 2002, they are not holding up as well any more (will only run the fridge for 48-72 hours) and I'd say I will be looking to replace them soon. The vehicle has had a mix of being a day to day transport and some fairly long periods sitting. It's never failed to start in the last 7 years due to battery (or any other reason).
I think I'll be replacing with same or similar.

My yellow top only lasted 3 years before starting to leak from the negative terminal, and it had lost subjectively 20% capacity.
I fitted a Chinese "Absorbed Power" 90 AH AGM about 4 years ago which has almost twice the power and at half the price, and is going strong.
Guess what I will buy again?
