## Description

Add versatility to your toolbox with the DEWALT 18V to 20V Adapter that allows for the use of 20V MAX* batteries in most 18V DEWALT tools.

Review: These work great on my 18v XRP DeWalt tools! - I was really bummed when DeWalt discontinued the 18v XRP line of cordless tools. I have 10 tools and it became impossible to find new batteries for them. I was happily surprised when this converter came out - it works great and allows me to use the 20v batteries which are readily available. Sometimes, it is a bit stick when you try to remove it from the tool and requires a good tug to get it off, but that is a minor issue.
Review: Good investment - These adapters work fine. Easy to convert my 18 volt tools to 20 volts. Other reviewers said they were hard to remove from the tools so I purchased several so I don't need to remove them. The only negative is that leaving batteries connected with the adapter over time seems to drain the battery . I left one connected in my circular saw for several days and the battery was completely drained. Recharged fine.
