After some effort to dispel the lingering myths from the 1980's about rechargeable batteries, I bought a MH-C204W charger for the office. It is so simple and reliable that even my most technically-challenged co-workers have no problem. I plan to eventually replace all disposable AA and AAA batteries in my department with rechargeable. We're going to save bundles of money for sure. Thanks again, Paul, for the great products, reasonable prices and speedy service.
