Whats the matter with going back to 8-D's?
BTW, if youhave a catterpillar dealership, you can get Genuine Cat OE
batteries for about the same as aftermarket.

One thing is , like chuck said, is that Cat doesn't ame their own
batteries, but who ever makes them has to make them to Cat's specs.
and they have good specs!

On my trawler my present house battery bank consists of two 8Ds, my
starting battery is a 4D.

The 8Ds are ready for replacement. I'd like to go with golf cart
batteries.

Costco has them for $62 each. No real information on the card in the
store. West marine has them for $127. There is not enough information in
either place to compare them to each other.

Several sites on the Internet have Trojan golf cart batteries, and there
are many choices, for prices that look like $200 and up.

I have a lot to learn about batteries. I don't have enough information,
yet, to compare what I'm seeing.

Then there's the issue of a new "Smart" charger. My 20 year old charger
probably needs to be upgraded with the batteries.

Your input would be appreciated.
