Battery bp-hp550-11/2.4v 550mAh does not hold a charge, can I use regular AAA batteries, if not where can I walk-in and purchase new ones

Even though you can use regular AAA batteries (that you would have to replace often), there is a huge convenience factor with using the charging cradle that comes with the Sony headset. A solution I found was that I ordered some 550 mAh AAA batteries through Ebay (they came from England and cost me $8 total for four batteries). To make the charging cradle work with the new batteries installed in the Sony headset you MUST use the bottom part of the plastic battery holder piece on the BP-HP550-11 battery pack (all you need to do is peel off the BP-HP550-11 label and the bottom half of the plastic battery holder piece slips off of the Sony batteries). Then just slip in the new AAA batteries into the plastic battery holder bottom and then insert into the headset. The reason why you must use the bottom of the battery holder plastic piece is because the plastic piece pushes on a little switch. This switch activates the charging mechanism inside the headset to enable the cradle charger to charge the batteries.

NOTE: I am not an electronics expert so I do not know if there would be any problem using other rechargeable AAA batteries (with higher mAh ratings). So I decided to be safe than sorry and ordered the 550 mAh batteries through Ebay.

Since many Sony headsets use the BP-HP550-11 battery pack, I assume your battery pack is the same. If not, I assume whatever battery pack your headset came with, it is some type of plastic holder that holds two batteries together.

Sony has some special case they put around the original 2 batteries to hold them together.

You don't need to buy special batteries. You can put regular AAA NiMH in.

To remove the compartment cover on the headsets make sure you hold down the pressure button on the left headphone to release the cover. Mine has the words "PUSH" on them.

With the cover removed you can then see the original BP-HP550 sony battery. Which you can remove and put 2 regular AAA batteries in.

You can actually use two regular dry AAA batteries to power these headphones, the only thing is that you will not be able to charge those batteries with the charging station that comes with the headphones.
