Review on NiteCore D4 Charger with LCD Panel Display for Li-Ion, Ni-MH, Ni-Cd Batteries – Including CAR-Adapter and Bonus Battery Box by Shane Miller

Great charger. The charger automatically detects what type of battery you have and changes the charging settings for that specific battery type. After charging batteries that I had charged many times before and which didn't last long, the same batteries lasted longer after just one charge with this charger than since the batteries were first purchased. This is not a fast charger and it takes about 4 hours to charge the batteries, but you can charge different types and sizes of batteries at the same time.
