Check this tool out.....

I actually have that and a couple of other Worx tools - the batteries do tend to run down pretty quickly, but now that I have 4 or so of their products I never have to worry about it - there are always at least 2 charged up and ready to go and there is always one or two on the charger. That particular piece (the Switchdriver) is excellent for quick repairs. I like 'em.
