Has anyone ordered this type of battery from Amazon? If so, have you had good or bad life from them? I have had very short life and won't order from them again. I'll post a longer message with specifics if anyone is interested, but don't want to write a book right now.

Thanks
 
The three things I have found with AGM batteries. They need to charge at a little higher voltage and NOT go over voltage. Mine runs around 14.3 in my Expedition. Next is if sitting for a long time for goodness sake put a good charger/maintainer on it. Also don't try and run one of these into the ground trying to start something. They like to stay at very close to full charge so use that maintainer. The type that pulse the battery. Around 25 or 30 bucks. Schumacher is the best I have seen.
 
charging at 14.3 or 14.4 is required for AGM batteries. For 12 years I used gel cells and they lasted because I charged them at 13.8. I like AGMs but they are finicky.
 
You do understand!!. It is amazing how powerful those batteries are. One time I was on a photo shoot in Cumberland,md. Got down to like one or two degrees that night. The next morning I go to start up my old Dodge Caravan and she pops right off. Coming out of the next room over is the owner of a Brand New white Dodge Diesel Ram with jumper cables in hand. Had him running/ started about 4 minutes later. Then the guy next to him with a station wagon got a jump too. They were both amazed by how much power that Interstate Optima battery had.It only got up to 16? that day. If your vehicle has a good charging system those are some of the best batteries you can use.
