A:AnswerSteady amber light indicates charging of the rechargeable AA NiMH batteries is taking place - continue charging until the amber goes off or turns green. However, a flashing amber light indicates batteries are either: incorrectly positioned in the charger, or not correct for the charger, or may have a dirty terminal (clean off the battery terminals), or one is defective.
A:AnswerYes, I use it to recharge eneloop batteries. It only charges AA batteries, though.
You should know that this charger has been discontinued some time ago and the batteries that come with it are old. Two of my batteries did not work.
The charger is still good.
