I need to replace the starting batts for my 400hp Cummins.The current batteries are AC Delco 31TS (950 CCS). Need good batteries at reasonable prices. Any suggestions?
Thanx in advance.

Got my house batteries from Costco last time. 4 Golf cart batteries, that was in 2013. going to change them again before the next long trip just to be safe.

When I was in Corpus Christi last October I went to the local Freightliner dealer and they had a sale on batteries 950 CCS, $69 a piece...this was for my Cummins ISL 400...call around!

Use petroleum jelly on the terminals to avoid a lot of corrosion issues. (Once everything is connected of course)

I use AGMs for house batteries but engine batteries are not bad about causing corrosion. I replaced my Interstate batteries at 10 years... not because only one would still start my ISL but I was in OR so no sales tax and they let me keep my old ones. I'm still using one of them at 13 years. Cost/year should be considered.

Get AGM. No more corrosion.
