After using the batteries well for 4 months, one of them is looking a little 'puffy'? Should I be concerned?

yes you should be concerned first of all it won't fit back into your phone properly second is a lithium-ion battery they have been known to explode they're cheap enough throw it away get a new one

Same problem here; one battery swelled while in use, enough to pop the back off the phone case. It was hot to the touch; I thought it might burst. I came on here looking for warranty information.

YES YOU SHOULD BE CONCERNED. Do not use the battery as it may create a hazard. Dispose/recycle appropriately or return to manufacturer/seller.

You sure about the batteries, if not might be a short. I wound check with CS, they have been there for me.

Mine is still working well, however, I just use it occasionally. If you are sure that your batteries are good, I have no idea what's wrong with it. You can try contacting their customer service.

I have had mine for some time and don't recall that it was a problem when I installed the battery. Sounds like you may have to return it and get another, BTW, I do like (and trust) the unit.

I don't have any issues like that with my battery.. I'd see if the seller would replace it with a new one

I did at first but I realized it was the batteries causing the problem. Charged them up overnight and it has been fine in the cold now.

I know the batteries tend to drain really easily so did you check and see if new batteries help?

I have had mine close to 8-10 years, and have changed the batteries 3 times at most. I only do small areas though like the upper lip. Are you doing multiple areas at once or larger areas like your legs? I haven't had the same problem with mine. Can you exchange yours? :/

I am presently out of town and unable to look at the ones I have. I have never had a problem. They are always well charged and quite btrght when darkness falls. I will be home the end of the first week in Feb and would be happy to check and see if the batteries are replaceable. Off hand I think they may not be, I recall they are well sealed.

Yes it's normal.. To get the most use, fully discharge and re charge 4-5 times. You will see a longer lasting battery

I have used it for about 4 months and the battery symbol still shows full bars.

My batteries are working fine and they have been installed for about 3 months. The electronics appear to remain off until activated by a finger print scan or entering the security code. Thus no apparent battery usage.

My batteries last about a month. I got a value-type pack from monoprice, so they're not the greatest, but they still last a while. Not sure why so many people are having issues, maybe the battery compartment gets wet from splashes or condensation for them?

This is only a guess, but I would remove and inspect the batteries and re install.Clean the contacts if needed and maybe a LITTLE lubricant.

That's a tough one to respond to. If it is a genuine Sony battery and there is no obvious damage, I would certainly try returning it. I don't know what the warranty is, but I would suspect it might be a year. Batteries are mass produced and like any mass produced item, you are bound to get a defect every now and then that makes it out of the factory. I've had no problem with mine, but yours is several months older.Good luck.

I would check that your batteries are pushed tightly down into the compartment. I haven't had any problems with mine at all, so I'm just guessing here. Good luck
