## Main Question or Discussion Point

I have 2 batteries for my mobile, and forget which one is new and old.

The standard volt is 3.6 V, and I measure the voltage using any standard electric meter.

Battery A has 3.86V

Battery B has 3.77V

Does anyone have any suggestions on whether it is possible determine the new battery based on measured volt or not?

Thanks in advance for any suggestions :>
