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.
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.
