Where to get the battery?

2025-11-21 14:09:53 Ask

Hi!

I bought this "mini keychain" but it didn't come with a battery and apparently it doesn't even turn on without one: what kind of battery should I buy? Any advice about where to buy it?

Ok, let's summarize now that I have registered... ????

  1. How many mAh should the battery have?
  2. What is the maximum size?
  3. How many pins the connector should have? Is it a " JST 2pin connectot" or does it have another name?
