I know this may cause a debate, but I had an International Battery in my previous SOB 5er. During the first 6 mo of use I lost a converter. Only the charging part had gone bad. Had it repalced and about 6 mo later another converter. Could not find out what was causing the problem until I tested the battery. Never would fully charge. I took it out and put it on my bench and put a charger on it for a full day.. Never got to full charge. Took the battery to Auto Zone and had it tested. Found it had a shorted cell.
That was the third Interstate Battery that I had go bad. I believe that is what caused both converters to go out.
I will never again use an International Battery.
That is my 2¢ on the subject..
