Cordless 3/8" Drive Ratchet

I have a cheapo "Power Torque" I got from O'Reilly when I worked there. It's about 3 years old and I've abused the hell out of it and it's still going strong. I was so impressed I also got the 3/8 impact and the drill that doubles as a 1/4 impact driver. My only complaint is, even though they are lithium-ion batteries, the charge doesn't last like it should. It lasts plenty long enough to do whatever job I am doing. Once put away for a while, they lose a good bit of their charge. That's a stark contrast to my Hitachi 1/4" impact driver. I can go out months after a charge and it's still kickin ***. They are good tools though for what they cost.
