As long as they are NiMH batteries, the 950mAh should also work perfectly. VG

Hi, I had the same problem, I wanted to use other batteries because the originals are not available to buy. You have to buy 800 mAh or even better under that to charge the brand doesn't matter. Then scrape off half or all of the foil, it doesn't matter, you can see the blank battery, these then go into the Philips headphones for charging.

Hello,
Unfortunately not, you need AAA NiMH 900 mA batteries. I tried 950mA, but it didn't work. Like you, I am desperately looking for 900mA batteries.....!!! Let me know if you find any. Have a nice day.

Here is an explanation from a specialist as to why more Ah doesn't do any harm, but simply provides the required amperage for longer.
"Ampere is the unit of measurement for amperage, which indicates how much electrical current flows through a conductor. The capacity of a battery is measured in ampere-hours (Ah), which describes the amount of electrical charge that the battery can store. A higher Ah number means that the battery has a greater capacity and can therefore be used for longer before it needs to be recharged. Ampere-hours are also referred to as nominal capacity and indicate how long the battery can be operated at a certain discharge current. For example, a rated capacity of 10 Ah means that the battery can deliver 1 ampere per hour for 10 hours before it is discharged."

I see this in the same way as the previous writers. It doesn't matter, so no problem.

agree with hjwidmer: should work
