Battery Adapter Charger
How do I make a charger adapter to charge 12 AA batteries (1.2v/2000mah each battery) in series?

Hi
What are the voltage and mAh output? Output means the output from the adapter.
How many hours does it take to charge these 12 AA batteries fully?

Thank you

You will need at least 14.4 volts, and you can probably go to 18v safely if you put it on a timer. The adapter ouput in mAh determines how fast you batteries will charge, and too fast will heat them enough to explode! Definately stick with less than 1Ah (1000mAh). But, for the first time, you may need to take the batteries off every hour and test their voltage to see how long until they get to 1.3v (fully charged).
