Identify faulty soldered PCB Lithium button cell replacement battery
Can someone please make a professional guess as to what battery voltage and type (rechargeable or not) I need to replace the dead battery on this circuit board?
I cannot make out any info marked on the existing battery. It got a little scratched up by me when I cleaned the corrosion off it to try and get it working again.
I am pretty certain it is the battery that enables the device to remember the clock setting, as this is the fault with the camera.
The battery is approx 7.0mm diameter and 1.5mm thick. It reads 0.47V on my multimeter.
I understand these cells are often 3V and rechargeable type but I want to be sure.
The circuit board is from a wildlife camera trap (sometimes known as a Scout Camera) about 5yrs old, powered by 12v DC.
Es esta una buena pregunta?

As this one is soldered in, does that mean it is the rechargeable type?
