Good day guys,
In my new circuit, I will need to often replace the coin cell CR2032 battery.
Since sliding the battery into the flat holder request each time some force, I am afraid that the holder soldering points will break after some time.
Thus the question : what is your favorite CR2032 and what is the best known way of fixing it flat firmly to a PCB ?
Glue ? Screw ? Soldering ?
Thank you
I guess that depends on which battery holder you choose. Also remember that most applications that use a CR2032 expect the battery to last a long time and therefore fewer insertion/removal cycles.
The ones that are simply bare metal "clips" require the PCB to provide the other battery contact which could over time start to wear the copper away.
I would stick with one of those horizontal plastic/metal ones with a simple retaining clip as used in a lot of PC motherboards.
Thank you. Any experience with those ones ? Are those strong ? Or crap ?
If they are solid enough than I may just glue the plastic
That will not be easy.
The flexible and slippery plastic is difficult to glue, thought rubber cement may work.
To be honest, they look like cheap crap. They appear to rely on the plastic catch on the lid to keep them closed so the coin cell keeps touching the battery contacts. If the plastic catch breaks/fails, then the coin cell escapes into the innards of your project - where you will have a nice piece of conductive metal coming into contact with all sorts of things it shouldn't!
PTH instead of SMD.
Perhaps a better question is why you're using a frequently replaced coin cell instead of a battery with longer life?
I was kind of expecting that question 
This is for a wearable project. Tiny / flat format needed.
Maybe describe your project. What devices does it have and how long you would like it to run for on a single 2032.
