Mephisto Senator - Button cell (battery)

Hi,

I would like to ask users of the Mephisto Senator module (and also Magellan) if you have problems with the internal button cell. In four Senator modules that I have had the opportunity to inspect, the button battery was totally discharged, dead. When I check the standby consumption, I find that it is very high, between 20 and 40 mA, depending on the module. In the circuit powered by this battery, there is an electrolytic capacitor, but in no case was this capacitor faulty, there was no leakage (of electricity, I mean) except for a few microamperes in one of the cases studied. A preliminary analysis of the circuit shows a poor design. I would like to know if what I have seen are isolated cases, or if you have also seen this behaviour, where the button cell runs out of power very quickly. Thank you!
