The six compartments charge separately from each other, so any combination of battery sizes and types can be charged at the same time, and batteries can be taken out as you need them. The charger can charge NiMH, NiCd or rechargeable alkaline batteries. Microcontrolled charger recognizes the battery type and charges accordingly. LED lights indicate "charging" and "ready". Maximum charging current is 700mA. Charges using 120V AC houshold power or 12V DC, vehicle or solar panel. 2 year warranty. You can plug these chargers directly into a solar panel, the 12W Sol-Charger solar panel (about 600mA) is acceptable for solar charging. The 12W panel could power one charger at about 75% of max. charge rate or 600mA.

When you insert a battery into a charging slot on the AccuPower AP2020, the LED is *supposed* to start blinking, indicating that a charge is taking place for the battery in that slot. But if the LED doesn't blink, don't despair. Your battery might NOT be unrevivable after all, merely drained beyond the point of recognition for this charger.
Working on a hunch, I took 2 strips of aluminum foil (about 3.5" X 0.5") and inserted them between the ends (poles) of the batteries and the connectors of the charger--one strip for the positive end and the other strip for the negative end. Then I set a "good" battery on top of the dead one and touched & held the foil strips to the corresponding battery poles. (Yes, it's basically the same idea as "jump-starting" one car battery with another: positive to positive, negative to negative.) Sure enough, the LED started blinking! After a couple of seconds I released the "good" battery from the foil strips--and the LED continued to blink! The next day I had a fully charged D cell which I have since recharged countless times with no problem.
Conclusion: once you "trick" this charger into initiating a charge, it will continue and fully charge the battery...at least that's been MY experience with LSD NiMH rechargeables!
update: sometimes simply unplugging the AC adapter from the charger and plugging it back in will cause the "dead" battery to commence recharging...sometimes not. I like to keep my aluminum "jumper cables" nearby!
When trying to test the charger I have unplugged it to try to reset it and put the batteries in again - same thing. Unplug it and plug it back in with the batteries already installed - same thing. No matter what, I can't seem to get a good charge with this thing. Also according to the instructions when you first place the batteries in the charger the LEDs are supposed to stay lit solidly for three seconds while the charger "analyzes" the battery. Mine does not do this and goes straight to the charging mode - blinking LEDs
Looks like I will be returning this unit. Unsure if I want to exchange it for another one of the same. I paid $55 for mine which is a great price for this product (if it worked right) from Amazon through a 3rd party seller as I believe list price on this unit is $79.
I came across this charger and saw that it not only handled 9V batteries better but that it can also charge most other standard size batteries. The status light for each slot lets you know what is going on and you can mix battery sizes.
This unit costs more but you get more. The quality of the charger is good too as it seems well made.
