My coach came with 3 of the Exide px-31 925 batteries for chassis and after 8 years are shot. When I do a search for this, google comes up with O'Reilly Supper Start Fleet &Heavy Duty Battery Group31P Part # 31-5 Does anyone see a problem replacing with these batteries? I looked at the specs and do not see a problem but I might be overlooking something.
If you keep them at about 13.2V when not on the road, they should last 8 to 11 or so years. The heavier the better is usually the rule for batteries. Look at 60 lbs or more. You should get a 10% discount for buying 3. Auto Zone gives me the discount. We also have three 31 series for engine batteries. Should give you about 2850 or better CCA. Somewhere around $300 to $330 should do it for all of them.
