My old one charged at 1000mAh for 4 batteries and 1500 for 2batteries and would charge in about 1 hour to 1.5 hours...then new ones only charge a a max of 700mAh, and will take about 2 to 2.5. The problem is when you charge soo fast it destroys the batteries. 700mAh should be max or you will overheat the batteries.
I like this charger as it will refresh the batteries until you get no benifit...ie charge fully, Discharge fully, Charge, Discharge, Charge, Discharge, Charge, Discharge until there is no gain in battery capacity. This charger has soo many features and lets you decide what you want to do... If I am in a hurry I will charge at 700mAh but If I am charging overnight I will deep discharge fully and charge at 200mAh.
I love this charger as it is not that fast and will not cook the batteries, fast charge is nice but I have been reviving all the old batteries that I own and then fast charged battery's never last long.
