How long does it take for Apple's AA battery charger to recharge?

I'm talking about the charger that comes with their new Bluetooth trackpad and keyboard.

If I put 2 empty batteries in it now, how long till they're full?


Usually 4 to 5 hours for me to recharge the 2 AA batteries. Basically I recharge the batteries when its power is lower than 10%.


Apple has said that it may take up to five hours to charge the batteries.


Mine usually seems to take about 3 hours for completely drained batteries.
