Hello i have several sensors and tags that run on CR2032 Batterys. When i receive them they work fine with the factory battery. But when the are empty and i replace them the battery status says 1% for the new battery. It does work for a short while and then it gets emtpy again.
I tried differend brands, like duracell and Varta but no difference there.
it drives me crazy.
Does someone have a simmelar problem and hopfully a sollution.
Or does someone have a glue what i am doeing wrong?
Those watch batteries are also very sensitive to the oils on your hands, when I replace them I never handle the top or bottom directly - either carefully on the sides or with gloves or tweezers if needed. Although I don’t know that I’ve ever heard of batteries dying so rapidly as a result of poor handling, generally it might shorten their life but your situation seems extreme.
What devices? Who makes them? Perhaps the devices themselves have a flaw.
A higher capacity CR2032 woud be a CR2045! (the last two digits are the thickness)
Seriously though, cost seems to be a proxy for capacity. Cheap CR2032 don’t last, with the possible exception of IKEA multipacks which are fairly good.
Another issue is some cells have a bitrex coating to reduce the chances of a child suffering major intestinal damage, but this coating can be an insulator. Some cycle power meters didn’t work at all with some brands - without sanding off the coating.
If you search you can find the monster IKEA 5-button remote thread with the hack fix of a 2x AA battery holder and soldered wires. Very high capacity alternative!
I ended up by buying LIR-2032 rechargable batteries. They should have less capicity then one time batteries but the last longer in my case because the have almost no voltage drop until the are empty.
