This battery pack is a complete rip off. I own two pairs of Sony wireless headphones model MDR-RF925RK, and they both came with these packs.

After taking them apart, I realized they're just standard junk quality 550mAh Sony AAA batteries in a plastic holder.

On my wireless headphones, there's a built in recharging function, but if you try to use standard Ni-MH rechargeable batteries it won't work. The reason is because the unit has a tiny hidden switch inside the battery compartment. If you use these battery packs, it pushes down that switch and enables the recharging function. If you use standard rechargeable AAAs, they won't push down the switch due to their shape.

All you need to do to use standard rechargable AAAs is to find that switch inside your unit and superglue it in place while pushing it down with a toothpick or something. I have Eneloop AAAs in my headphones now and they last a lot longer than they did with the Sony battery packs.

Thought the price for this battery was too high at a local battery store. I went online to see if I could fine one less expensive and found it to be about the same money. In reading reviews about this battery, I read how this battery can basically have 2 AAA rechargeable batteries installed in the plastic casing. I decided to try it and although it took a little doing to remove the 2 existing batteries, I was able to do so. I then inserted 2 replacement rechargeable AAA batteries in the casing and placed them in the headphone. It worked like a charm. I am so glad I did a little research, read some helpful reviews, and saved alot of money by doing so? $20 for a battery...not worth it for just a little effort.

Purchased this battery to replace the original one that came with the Sony earphones. It works great! Holds its charge as advertised. And, cost is attractive. A great choice when looking for a replacement battery!

Cut old batteries out of plastic holder- the holder is in two pieces- replace with good quality rechargeable AAA batteries and put clear tape around holder- cut slot in tape at bottom of holder to allow holder to go back into compartment- enjoy!

I have found that some replacement batteries die very quickly, NOT this one. It appears to last as good as the original.

New battery with it's larger capacity has longer life than the original equipment. It is the same size so no issues with fit.

I've had my new Sony Replacement Battery installed for about 6 weeks and they are operating as they should. On the initial charge, I allowed the battery to charge for about 30 uninterrupted hours. The original battery was a nickel-metal-hydride and it lasted about 4 years. It's only been 6 weeks for this new Ni-MH battery, but so far so good.
