How to replace the battery!

Hi!

iFixit does not have a dedicated guide for this specific model. With a quick search I could actually not find a guide for battery replacement either.

However, based on the product image, I would bet that the batter is on the left side (or the same side as the charging port assuming it is on the left side).

Also by looking on the product image, I don't think you'd remove the cover from the outside, but from the inside by taking of the ear pad and thus exposing the screws holding down the speaker. By unscrewing these screws, you should hopefully see a circuit board and or the battery. Warning, when taking of the speaker, the motherboard will still be attached to thin wires!

These guides are not for the same model, but at least based on exposing the battery from opening the headset from the ear pads. See JBL Tune 600btnc Battery Replacement and JBL Synchros E50BT Teardown.

Please respond if my guesses were right, or how you solved it!

If you want, you could even take a few pictures and upload for a guide!

Good luck!

cheers!
