Batterry recommendation for Class A Diesel

[rpgibbs]

I am going to replace my current coach interstate lead acid batteries (4) in my 2005 American Tradition. I would like recommendations on a good to top of the line Sealed Deep cycle AGM battery (group 27). Thanks

is anyone here familiar with these

It is a little known fact that no lead-acid battery "likes" to be on a constant trickle charge for weeks on end. Connect your trickle charger to a cheap mechanical lamp timer and set it to run the charger 1-2 per day.

If possible, find someplace to store your batteries <80F. Outside or in a garage in AZ is too hot.

Thanks Wiz!

I did WM deep cycle marine parallel for Cat C-7, works fine, will do the same when the four six volt go bad.

could be. most likely the last five years or more they would have pretty much useless as far as lasting more than a hour two when off shore power or being charged

I went 14 years on the original equipment battery in my E150.

I did clean and water it (yes, it was a maintenance free battery) about once ever 12-18 months.

Last set I bought at Sam's for $46 a piece was still usable after 12 years.
Having advanced inverter/charger I recall adding water only twice in 12 years.
YMMV

WOW ! Amazing !! I think you should have upped yor watering cycle, but you can not argue with success.

NAPA group 31 AGM batteries are made by "East Penn" You can order from any NAPA store. I purchased mine in Oregon and no sales tax.
NAPA store in Tillamook, Or. also installed them

Rolls-Surrette S6-275AGM. 5 year warranty, 2 year free replacement, three year prorated. In my book they are the finest battery made.

One of the best brands out there.

Trojan is also good, 27-AGM. If you have a couple of inches of extra space I would recommend the Trojan/Reliant T1275-AGM. 270 minutes @ 25A discharge rate versus 158 minutes @ 25A.
