They say on their website that you shouldn't charge an AAA and a AA in the same bay. Quote: "4 LEDs show the status of charging, never charge 1 AA + 1 AAA together at 2 slots which are controlled by 1 LED." What do you think?
I order 3 and all of them have hissing sounds as soon as you plug it in(no batteries connected). one is so loud that i can hear it 7-10 feet away. Is the hissing sound present in your device? the other 2 has hissing sounds barely noticeable but if you put your ear near it, you'll hear it. Can you please try it on your device? Thank you so much
I have heard that mixing AA and AAA in the same slot is dangerous. Is this true? I do recharge AA and AAA at the same time in this unit, but in matched pairs.
The one I have doesn't charge at all. I put in dead or dying batteries and it only shows green. Never seen it show a red light yet. My old one works better than this one.
+Jason Matthew no problem yes just make sure that they are rechargeable AAA batteries and they will fit in there and the charger will charge them doesn't matter what brand as long as they are rechargeable
