Here's a tip: Replacement batteries for cordless tools can cost almost as much as the device itself. Interstate batteries delivers to me every couple of weeks, and when my batteries start failing to hold a charge, I send the original manufacturer's batteries in to them....they diassemble them, and replace the cells. Good as new, still in the oem packaging, and lots cheaper.
That's good as long as the batteries do not contain Lithium. No one wants to work with Lithium b/c it is highly reactive.
