Couple months ago i got myself used AKG T912 headphones. They can be used with regular battery or rechargeable.
Question is how whey prevent from recharge a single use battery when someone stuff it inside.
Answer is a third contact for recharge touching body of battery.
To be able use rechargeable battery, it need to have striped part of battery body to allow third pin contact – and then be recharge.
So if You fit rechargeable battery inside AKG T912 and they not charge – check for contact to body.
On pictures bellow You can see how it works.
Thank you so much Sir, this helped me revive the old headphones sitting unused for like 7 years with completely dead old batteries.
I was going crazy last night wondering why it was not charging my new batteries.
Thank you thank you thank you
Hi Dear
I am facing the same problem with my AKG K912 headphones. I love the headphones but cannot recharge them. Can I use a standard rechargeble battery and “remove” a part of the insulation cover towards the Negative Contact so the side contact of the rechargeble battery? Will it work??

Yes, that’s what I done! Regular Eneloops + stripped insulation.
Thank you, very helpful!
Hello all, I’m still stuck, I cannot charge or tune. Both red lights are off, however power on the cradle is on and power on the headset is on too. Please help.

Thank you, very helpful!
A big big THANK YOU, that’s really saved me. Very helpful. Cheers from Italy.
Same in AKG K915. You’re great, man!
Great tip! I managed to make contact with the charging pins by wrapping a small piece of aluminium foil around the bottom of the battery, bridging the negative contact with the charging pin. Might try this instead.
