Ultra-compact 12-volt lithium ion batteries have become extremely popular in recent years, and they've found their way into all sorts of tools and other products. Several of the top tool manufacturers have embraced this technology, and have introduced entire lines of tools around this powerful and lightweight battery platform. Some of these tools are easily recognizable, and some are, well, maybe not quite what you'd expect.
A number of different products utilizing these great little batteries have come my way in recent months, so I've had the opportunity to try some of them out. This seemed like a good time to give you a roundup of some of the better choices, both for your own toolboxes and, with the holidays upon us, as gift-giving possibilities as well.
