  1. Les B

    Excellent charger, it has a great LCD screen that displays voltages as it charges. I charge 2600mah and 3400mah batteries on it and they complete in reasonable times due to it’s ability to charge one battery at 500mah or 2 batteries at 500mah. I personally like to see what is going on rather than just blinking bars.
