another source for agm batteries
Hi, It's time for me to consider replacing four of my batteries that are now 8 years old. I came across this on Amazon. Any one have an opinion on this company? http://www.vmaxchargetank.com/...

That's a strange quote. Usually they base everything on 80F or 25C. If max at 20C is 14.6v it is less at 25C.
If you think about it, when a battery's AH is rated at a lower temperature, 68 v.s. 77F, that battery is going to have more AH at 77F.
It is a marketing blunder to spec at 68F as the unwashed will not understand the temp effect on AH. If the other brand 77F rated battery is 80 AH, which one is better? More may actually be less!
