The charger comes with 2piles AA and 2 AAA batteries. The charging time is respected PIUR AA batteries, 4:15 for the first 2 and 4:45 for the following 2. By cons I put in charge 4 AAA Batteries (small batteries), the first 2 were loaded in 6:45 ET the other 2 in 8h. My complaint is that the charger 4 batteries that are placed together in the feeder have different charging times. So if you need 4 batteries it takes. On the other hand the charging time for small batteries seems to me very long, I hope it is only for the first charge.
