Deep Cycle Batteries. Which one to choose???

Nothing much has been posted to help you as you cannot take batteries with a 5/10/15 and 20year design life and say they are all the same.

You say your old battery has finally died so from your own experience how long did it last and what was it surely that would be a guide.

If not and you are prepared to maintain a flooded wet cell the Crown Supreme would be worth considering as deep cycle is based on years of fork lift use and crown is one of the biggest and a flooded wet cell is the cheapest way to go and will give long life if maintained.

Ian,
Thanks for the feedback. I used a Trojan 130ah wet cell deep cycle battery. It lasted around 2 years. It is mounted in the engine bay and would need the water topped up constantly (I assume because of the exposure to high temperatures).
For this reason I'm looking at a maintenance free battery. Also, I need a battery that can recharge faster than a wet cell. Size isn't an issue. I can accommodate a battery up to 380mm L x 180mm W x 290 H.
I think the Crown Supreme 130ah battery I put in my original post may be a wet cell. If so, that's a mistake on my behalf.
You mention design life of batteries. How do you find out that info? All batteries I looked at mention a life of around 8 years at the most let alone 10/15/20 years.

And KK, you are right about warranty. I will ensure I get it from a distributor in my home town.

Cheers for the feedback everyone.

Maxy.

A flooded wet cell battery is more tollerant of under bonnet temperatures and over charging because you can add water and if you killed one in 2 years then do not expect under the same conditions for a sealed battery to do any better because you cant add water to them.

So you have to figure why it only lasted 2 years and correct something or you will be just throwing money down the same hole but maybe quicker.
