layback,

You are absolutely correct about the shelf life of a dry charge battery that has yet to be charged. Years ago, that was the common practice at many retailers and jobbers. In the US, the last time I saw a battery dry charged was about 40 years ago.

At most US battery retailers, they have gravity racks and place charged batteries in them. When you get one out of the front of that rack, you usually have no Earthly idea when it was charged.

I replaced the battery in my airplane a few months ago, and it was the first dry charge battery I've dealt with in many years. It was a hassle, but it made for a nice fresh battery. About the same time I went to the Motorcycle place and got a new battery for my four wheeler. They dry charged it and told me to put it on a charger for 30 minutes. I was impressed.

Unfortunately many retailers in this country are much more concerned with expediency than with providing their customers with optimum products.
