Nothing that's probably not already been posted on here before but I kinda used it make my decision to switch from going with Interstate to the EverStart Maxx Marine Battery, Group Size 29DC which will save me about $150. I had considered the Optima's (which are made by the same company) but at close to $300 each with the Walmart EverStart Maxx and 2 year warranty on the down side I would still get 6 years out of it and on an upside maybe 10 yrs. or more for the same money when compared to the Optima.

Chatted with a battery engineer at Johnson Controls yesterday. He said that "Johnson Controls is very pleased the Wal-Mart group 29 RV battery is rated very highly by the leading consumer product review company" The engineer also said "Batteries sold by us to different vendors are likely to have different internal construction". This implies a Johnson Control battery sold to Wal-Mart may have different internals than a Johnson Controls battery sold to COSTCO or Interstate battery. Read the foregoing again: It reads MAY and it reads DIFFERENT. It does not read BETTER or WORSE. My personal advice as an old and cranky, retired, lead acid battery design engineer, is to weigh every well represented Johnson Controls RV battery and choose the heaviest. The
