Can you add an image of the holder?


Sorry hit the wrong button will send a photo


having trouble with the photo


Are you using the correct battery? There is a thinner battery which looks like the same battery but its not! The size of the battery is 20mm diameter x 3.2mm thickness.

Make sure you have the correct battery using a caliper to measure (use some electrical tap on the top as you don't want to short it out.

You need the BR2032 battery there is also a CR2032 which is physically the same. BR2032 and CR2032 are not exactly interchangeable.

BR2032 has a very low discharge rate per year and can last up to 7 years.

However, I read that BR2032 maintains a constant voltage (3) for quite some time and the degrades rapidly when failing.

The CR2032 has a more gradual degradation in voltage over time.

The CR2032 may be more accommodating to colder temperatures than BR2032.

The circuit that these are designed for may differ due to the different expected characteristics of the battery.

Aslong as the battery is making a good electrical connection you could use kapton tape or electrical tapes to help hold it down

If they don’t work you could try conductive silver epoxy but you would have a hard time replacing it again if you were to do that

Hopefully this helps

Any questions please ask
