I didn't know that and it's valuable info.Just to mention that DeWalt has adapters that allow the different form factor 20v batteries to work in the old 18V tools. The DeWalt adapters also prevent the use of the larger Ah 20V batteries. They also have a line of 60V tools now.
I retired a couple years ago and stopped the "battery tool arms race" after accumulating a good stock of 20V tools and batteries.
One odd thing I did notice with regard to batteries is with the 4AH batteries. The tools and batteries I bought through the company I worked for generally had 5AH batteries. A couple lights had 2AH. I scarfed up a couple bargains at a box store that has 4AH batteries. So far - knock on wood - the 4AH batteries are the only failures I've had.
