Discontinued Delta, Porter Cable, and DeWalt Batteries
If you need batteries for your cordless tools and the manufacture no longer has replacements, you might try a company called Batteries Plus. They say they can make them work like new again. This is a franchise business and has 450 locations across the US. You can find them at http://www.batteriesplus.com/t-sitemap.aspx or the phone number is 1800-677-8278. I have only talked to my local store and have not used their service at this time.
