Hi All,
After 10+ years of service, the Optima batery in my Amphi finally gave up the ghost.
I was going to buy anther one but hear that quality has deteriorated since they got bought by another big company. However, I really like having an AGM battery in the Amphi as they will NEVER leak acid into the hull, they can sit for a very long time without draining, etc. (they also work fully submerged!).
After doing lots of research I went with the battery which the latest Consumer Reports happened to rate tops in every category. As it is a larger group size 65 it also gives me more cca and reserve time. And yes, it is an AGM battery, in this case the Sears DieHard Platinum.
DieHard Automotive Battery, Platinum P-2 - Group Size 65 - Model P-2 at Sears.com
The Diehard Platinums are essentially relabels from a Odessy, an extremely well respected manufacturer of AGM batteries for the military etc. The Platinums are said to be far better in construction and performance than the Optima. They are not inexpensive but if this one also lasts me ten years I have no complaints.
In any event, given the damage that battery acid can do to Amphi's hull, this is one area where it does not make sense to save a few bucks by going to WalMart.
