Again, I'm not trying to “punish” anyone,-----snip of repetitive post-----
LOL! Neither will you admit that all this time I had a bad Optima battery. I've only pointed this out at least twice already and tried to give you a chance to 'fess up.
So for the folks who don't have the patience to wade through the whole thread: It was started by someone who was totally frustrated with his Optima battery problems. Ultimately he gave up on Optima and dumped the battery. I've had Optima batteries over a much longer period and tried to capture actual measurements of the performance (or lack thereof) and there has been a lot of good information and discussions posted by real Portal members.
I bought a new Optima battery in November of 2011 and posted up all of the problems I had with it as well as data on the charging problems and performance shortcomings. Recently I had the battery tested at Autozone, then by the dealer and then by the distributor and all of them pronounced it as BAD. Except for the official fire fighter Optima Jim that is.
This battery was defective from the start but I received no material or truly useful technical help from Optima here on the forum. There was a thinly veiled ploy by Optima to try to get me banned from the Portal but that didn't work. It was huge laugh though as it was so well, desperate. In contrast look at a classy vendor such as Adventure Trailers who bend over backwards to assist folks here and not try to suppress discussion of problems.
The thread is worth reading through with lots of good technical content from DWH and others including the discussion about the DC-DC chargers that can do a better job of maintaining a deep cycle battery than a car alternator can.
