Battery and Invertor Update
The Optima batteries, listed here, Optima Batteries 8052-161 D31M Blue Top Starting and Deep Cycle Battery, were also making us a little nervous. Upon entering the RV we noticed a very strong rotten egg type of smell. Tracking down this smell lead us to the storage bay where the Optima batteries we sitting. We found one of the four batteries extremely hot and hence the source of the rotten egg smells. This battery was so hot that welding gloves were required to handle it. This blue top Optima unit has a 2 year warranty and of course we were just past that time by a couple of months but I still made a call to the manufacture to see what they had to say. They did not seem at all surprised by the rotten egg smell or the heat of their product and only said it must have shorted itself on the inside. As far as warranty it is a solid 2 years and that is the end. No pro-rated anything just 2 years and you are done. I was hoping for 232.00 dollars each there would be some type of compensation, but live and learn, and buyer beware!
Now we were down to just 3 of these Blue Top things and after pulling only a couple hundred watts for an hour or so we were seeing the invertor displaying an error code pointing to batteries. This was the last straw for us regardless of how much money was wasted as the BlueTops were giving us the blues!
Further research into the RV solar world lead us to the purchase of four 6 volt golf cart batteries. Once they had a chance to be fully charged by the solar panels we started load testing them. We turned things on one at a time until we were pulling over 900 watts and did not see any error codes from our invertor and inside power was very stable. We got these Energizer Golf Cart Battery – Group Size GC2 at Sam’s club for 84.52 each. There is also an 18.00 core charge but hey we will get that back when we give them the Blues. So do the math here on this experience and choose wisely.
