I have a set of AGM batteries from Cabelas and they are awesome. They didn't cost much more than regular batteries and they don't need any maintenance and can take the pounding lead-acid batteries can't. I have 2 group 24's and 2 group 27's and they run my ac overnight off an inverter. If you go to cabelas.com they even have packages for 2 batteries and an automatic charger, and the shipping is very reasonable. I highly recommend them.

I had a Yellow top in my car when I had a stereo system, That battery was the ****. Without the car running, I had full power for close to an hour beating on the stereo! Plus it had more cranking power too!!! I still have my Yellow top, its probably going to be installed in the powerquest as a third battery for stereo.

Your money is better spent buying a good standard lead acid battery and maintaining it correctly.

Try a DEKA, some of the best batteries from a materials and manufacturing point of view you can buy. In my business I buy a heck of a lot of batteries and we have standardized on DEKA.

I don't agree when i had regular lead acid batteries I was always adding water to them and they wouldn't last much longer than 1 year.

I have had the Cabelas AGM's for more than two years and they haven't needed anything. Both types were/ are on automatic chargers when the boat isn't in use.

Maybe if you are in a cooler climate it wouldn't be a big deal but with the heat here and year round use the lead acid batteries were a constant headache. Another plus to the AGM's is they don't have a vent and they can be mounted in any position.

I sell batteries. Optima batteries are excellent. So are Trojan AGM's. The main problem is if you let them go completely dead you have hit hard with a large charger. A ten amp charger won't get them up from dead. You got to use at least 20 or more at first. Then after they are up a bit, you can use less amperage. I think this causes people to think they have a bad one when realy they don't.
