This is always a great conversation.
If you are going to get a lot of use out of them, choose the battery with the highest reserve capacity or highest amp hours. The less you discharge a battery and recharge it back to 100% (cycle) the longer the battery will last. This is very important.
Here&#;s the stats on the Interstate Batteries.

AGMs do have a lot of pros vs LA batteries, but I don&#;t think they are always applicable.
AGM pros over LA
&#; much less discharge between cycles
&#; faster recovery from large amp draw
&#; much more durable
&#; faster charging
&#; can be mounted in any orientation(layed on their side)
If these pros are worth $100 to you, by all means get them.

I bought the group 29 LA batteries from Interstate because of their reserve capacity. I had to make room to make them fit but it was worth it. They aren&#;t much bigger than the 27s in physical size. Less than an inch in each direction.
I think the Optima batteries are worth the extra money.
Purchased an Optima Red for my SUV, it was a great battery and lasted many years.

I typically wait until the battery dies before replacing, but was a little more proactive with my last replacement. Had a ski trip planned and knew the battery was weak.

Fools think their own way is right, but the wise listen to others.
