Replace rechargeable battery in wireless AKG T912 headphones

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.

    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??

    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.
