Well, thank you for your replies. I did learn something from, apparently the professionals, and that is to store the batteries off of the charger, and store them at a not fully charged state. But another said, and I know this, that a completely discharged battery is death. I guess I just try to keep my batteries not completely charged or completely discharged.

I'm 75 and retired but still fiddle farting with projects. I have a 20 year old Nicad Dewalt drill that I still depend on. I've replaced the batteries because I can use them to run the little cordless saw and another tool with them. It's time to replace those batteries too as I only have one left, and 4 dead ones sitting on my shelf. It's a stand by drill but heavy to use. The lithium drill I have is a Milwaukee 18 volt and I now have to replace the batteries again, as I only have one left. I did have a Dewalt I liked but I wore it out and thought I would try the Milwaukee. I think both are the same. So I have a whole lot of dead batteries. My issue is when I review people's experiences with both the lithium batteries that are OEM and the ones from China there is a really poor percentage of people who have good experiences. There is almost always between 10 and 20 percent of people, (on Amazon and on the Milwaukee website) who are saying the batteries fail after a short time or do not work at all. The unhappy people on Amazon say "spend more from Milwaukee and get a better battery", but the people on that website have a lower percentage of satisfied customers. These batteries are expensive even if I decide to pay $65ish for two. A gamble and the percentages say it's not a good gamble. Makes me wonder, again, if I should just go back to a power drill even if I have to drag around a cord.
