An AGM battery will typically withstand deep discharge and recharge better than a flooded battery, will withstand vibration better, and can be mounted in any direction becuase there's no liquid to leak out.

Those are great qualities, but for the average person who just wants a good reliable battery in their vehicle they arent going to offer much over a regular battery.

Depends on the application.

I've read reports that the Optima batteries "aren't what they used to be" (change of ownership?) and they are no longer worth the premium.

Optima has lost it. Odyssey are what we use in our race cars only now.

I believe Optima used to be made in the USA by JCI, now they're outsourced from Mexico I believe. I've been getting good service from NAPA AGM's.

For an average car I don’t think I would pay extra for one. One of my cars requires an AGM battery, so it gets one.

 

[Bullwinkle J Moose]

Great for motorcycles.

 

[yellolab]

For a boat: yup.
Motorcycle: yup.
Car: no reason to spend the extra money for AGM, unless it's for a car that sits for long(months) periods of time.

I travel for months at a time and my Sunday driver has to stay on a trickle charger. A couple of times the charger shut off for one reason or another and I came home to a dead battery. Switched to an Optima Yellow top and even if the charger kicks a GFI, I still have a charge when I get back. I also ended up putting one in my truck. I'm a believer in deep cycle AGM for any use.

Mini and BMW require AGM batteries, you also have to tell the vehicle the battery has been replaced so the computer which controls the charging rate can adjust the charging profile as the battery ages.

I prefer them due to less chance of corrosion building up on the posts and terminals. I have had to replace entire cables due to corrosion. I wouldnt buy an Optima though.. Northstar or Odyssey only
