[SOLVED] Help needed identifiying this JST(?) connector?

[bLindWebber]

Hi there!

I got the Ora GrapheneQ headphones from a friend, with a dead battery and I wanna replace it.

I took out the old battery, however I'm not sure what connector this is.
At first glance it looks like a JST connector but I measured the pin pitch to be around 0.75mm and the JST SH is the smallest I could find (with 1mm).

Connector front side

Connector back side

Connector with 1mm sliding caliper

Any ideas?
Thanks, bLind

Welcome to the forums, newcomer!

Considering you can't find the connector, why not splice the old connector onto the new battery? I'm assuming that the new battery only came with wires/leads.

Hi, thanks!
I have considered that, and if no one knows what connector that is, it's the only option besides replacing the female counterpart on the board as well.

However, it would still be interesting to know what connector I'm dealing with here, plus soldering those super thin cables often is a bit of a flub.

Can you take a picture of the battery its self, any make or model number on it?
Can you take a picture of the socket in the headphones?

Have you tried email customer service about a battery replacement or to see what the plug is.

according to one of their documents

Battery Replacement
The battery can be replaced by an qualified electronics professional. The battery is located
in the Left ear cup. The headphones use a standard 3.7V, 510 mAh LiPo battery with a socket
terminal.

I have contacted support, they have not replied (yet).
The battery has a number on it, but I couldn't find anything connected with it.

looking at the battery connector more, those wires are just pressed in. You could just buy a battery without connectors and press the wires in, reusing the same plug.

Do you have a picture of the battery itself, with the wires. Preferably with some kind of number on it?

If you're really patient, check out the connector library on Digikey to see if it'll pull up something. Typically they'll have mechanical specs like pin spacing so it should be somewhat easy to narrow down.

Thanks for the tip!

Digikey might also have a battery that would work. Even if the capacity isn't exact, as long as voltage, physical size, and connector is the same, it should still work.
