Except being physically smaller, how are they different from an Optima?
Do they come in 6 volt?

[qmdv]

I have quit liking Optima several years ago. The first batch I used seem to last forever on the ranch in tractors and pickups. But that was 30 or more years ago. I quit them about 20 years ago cus they seem to have gone down in the longevity department. Oh and I am 12 volt.

Have you read up on the differences between deep draw batteries and starter batteries? There is a reason they make 2 different kinds. They are different internally.

Absorbed Glass Mat (AGM) batteries have been in the Marine industry for a number of years and have been well accepted. They generally have low internal resistance which gives high cranking amps. They do have, however, have unique characteristics. They don't like being over charged; they'll out gas and won't hold a charge. AGM's also can be damaged if the are deeply discharged. They can be brought back with a high current jolt, but generally not by standard alternators or generators. As a tech from Balmar (high output alternators; 150-250amps) told me, "They're like swimming pools. They'll take all the current you throw at them".

I pulled the stock battery out of the aft area of my Cessna 182 and put one of these on the firewall. I love it http://www.batterymart.com/p-hawker-...t-battery.html

Exact same as this but more money cus it is FAA approved. Made by same manufacturer and same specs. http://shop.odysseybattery.com/p/pc680

Just looked at Summit for a Optima battery and it appears they took about a 25% increase in price!

I am using an oddysey pc680. I got the idea from CT32.
Here is a post about it.

I have had no problems with it in 1,000 miles.Always starts

I agree the Odysey is one of the best. Stay up forever and recharge quickly. Very powerful weight ratio. However, they are NOT cheap.

[JSeery]

I know the high performance street guys use them. I am looking to install one in a project I have going.

As I said I use the aviation version of the PC 680 in my plane. It has same cranking amp at the PC680. The engine in the plane is 6 cylinder opposed piston (like a Corvair) 470 cubic inches. Really works well So time to build a battery box for the 32.

In my '41 Pickup I decided to put the battery under the passenger seat. I went through an Odyssey and Braille 12 volt batteries. They both did not hold up and were shot in no time. What a waste of money. I then went with an Optima red top and it has been fine for three years.

I have had an Odyssey battery in my 32 for the last six years without issue.
Great battery.

I used to be a sales engineer for Douglas Battery, before they were acquired by East Penn/Deka. On the XS Power AGM, you'd have to go by either folks with experience with that item or any critical reviews you can find.
I've got Optimas in 3 of the 6 vehicles here. Optima has gone through several owners (Gates-Gylling-Johnson Controls), and with each acquisition they have suffered not only management but manufacturing changes.
Summary- sometimes you get a good battery and sometimes not a good battery. Beside the other things they don't like that have already been mentioned, they don't care to be left idle.... not even if not hooked up. The last one I had that sat for 5 years could not be resuscitated, no matter the technique. (I have seen them go longer than that and still be ok)

Another vote for the Odyssey. I have had one for years that I use for my high compression 350 Chevy engine and a tractor.Charges fast, even when completely dead.
