Batteries - sealed or not?

[bradtarga34]

I bought a couple of these last year, I believe they now go under the name of Delphi. Mine are 170 ah jobbies, they took the place of similar size 135 ah one that I had previously. I hope these last 10 years! I've had one of those battery refresher things that puts a reverse pulse through to stop sulphation, so hopefully that will help as well.

As for the "fit the cheapest ones and replace them every two years" advice, obviously the guy has more money than sense.

135 Euros for 3X110 Ah is hardly much money, taking into account that:

[*]The option to add water permits me to take full advantage of my Stirling and charge the batteries really fast.

[*]If anything goes wrong (flat batteries for one reason or another) replacement cost is low.

This of course is a system that fits my needs for heavy battery usage in my one month of holiday (fridge 24/7 etc.).

Anyway, two years was the original plan, I'm now on the third one and maybe I won't replace them.

I hope these make sense /forums/images/graemlins/smile.gif

If you have managed to find a battery that will last 10 years, please share the info as to type/supplier with the rest of us, so we can all benefit.

Indeed, did 14 years with a Delco Freedom 95 Ah. Replaced it because everyone shouted that it was criminal neglect keeping a battery this old. When tested, it still had 75 % of rated output.
