Does anyone else's charger make a high pitched whine? It changes pitch the more batteries I add.

Caused probably by the rectification of A/C to D/C current. The coils can vibrate under load. Either way, mine doesn' do it, send it back.

I did not have this issue. Other have recommended checking to make sure you have the batteries in the charger correctly (+/-). If this does not help your issue I would contact Amazon and arrange a return/exchange since they are most likely defective. I recommend an exchange since these are otherwise decent batteries.

This happened to me, too. I had to replace the batteries soon after installation. Since then I have had no early low battery chirping. All I can imagine is that the batteries that were included with the unit were old or weak from the get-go.

If the headphone has been working properly (problem just started) I would change the two triple A batteries. I keep a back-up set fully charged with a separate charger. I have experienced noise & other problems which were solved by changing input plug-in location (tv, cable box).

I have never had this experience while the battery is charging. I would say the sound is anomalous.

I noticed that as well. My old one was heavy. New one light. So, probably a more updated "solid state" charger. Voltage output is a little higher than my old one.

Rick, I had one my LP-E6 not play too nicely at first, and it would not even really provide a state of a percentage of load. However after awhile, I got my charger a few months ago, every battery charges and plays nice; both Original Canon and non Canon Batteries. Try reseating the platform where the batteries connect to, and see if that changes it any.

I've read other reviewers comments about exactly that, a high pitched whine like a camera flash charging up. All I can say is the one I got is perfectly silent. I keep it on my nightstand and have never heard anything.

There is alternator whine if the phone is connected to the charger, else it's very clear and pretty noise free (depending in the frequency you choose and possible interference with nearby stations). If I need power I connect an external battery to the phone which doesn't close the circuit and introduce the whine. For the price paid I've been pretty happy with the unit.

I have not had this problem. I use my Apple charger. Perhaps you should check the contact points on the battery to make sure thery are making good contact and they are clean.

OK!........4 or All of mine are making sequel and crackling sounds when a phone call comes in. I was told to unplug the charger and let it set for 15 minutes and then plug them back in. They are still making large crackling sounds and squeals! Now what should I do because I purchase the 6 set through amazon. The one out in the shop I doubt is a problem so I'm not worried about #6! Up until last week everything was great. Now I'm having problems and I put in new rechargeable batteries but I still get the screeching and scratching noises! Bruce HartogWildwood, FL 34785

I haven't had any issues with echos but you may want to try and adjust the volume on the back of the charger. I have mine set at #4. Hopefully, that will resolve your issue. :-)

When i bought the batteries i also replaced my charger because the charging light wasnt working. i suggest replac the charger asi did. buy enough batteries to switch out, keep fresh ones capped. when not in use pull batteries out of tool leaving it uncapped. completley discharge batteries before recharging them. hope this is helpful.

I have tge same batteries and they dont make noise. U probably need to get new ones. It could be defected or the charger

I have no idea what that is. You can check the charger specifications on voltage. As far as charging odd batteries is concerned, there are sliding charger terminals. It becomes a problem only of balancing the battery in the charging position after adjusting the distance between terminals.

I noticed mine will do that if the battery is fully charged. Is it possible that could be the case?

I think its a battery issue, have you replaced it yet? Does that happen while on the charger?
