On Friday night I had a little bit of extra time so I went on the Internet trying to purchase a few different items. One of the things that I wanted to buy was a Makita Battery 9000. The one I have now has been used quite a bit and I recently purchased another power tool that requires the same battery. Since I am a building contractor I can always write off on my taxes purchase of any new tools. Not to mention the fact that oftentimes one of my guys on the crew walks up to me and asks me if I have an extra battery.
