It was the first time I'd tried something like this and, since sometimes the battery is the post expensive part of a power tool, I was really hoping I could get them charging and fully working again. One is a DeWALT 20V Max Lithium Ion 5 AH battery and the other is Milwaukie 18V 2AH battery pack. | TronicsFix | Facebook
