T&T: 1) Alternatives to 8D batteries are ? 2) How are the Odyssey Batteries?

[Keith]

Before you replace them, there seems to be a problem with your charging / 
maintenance. No batteries should need to be replaced that fast. My first 
question would be are you using an old ferroresonant charger? Probably 
should replace with a three stage "smart" charger. Here is a very good 
battery tutorial: http://www.batterystuff.com/tutorial_battery.html

That being said, I replaced each of my 8D's with two six volt AGMs wired in 
series to give 12V. At that time I also switched to a smart charger. They 
are all 4 years old now and going strong.

Rolls also has a modular system that's pretty neat. Uses modular cells that 
weigh about 30 pounds each to replace your 8D's. See
