    OK, I see in the TPS61200 datasheet that there is a hysteresis on undervoltage lockout threshold. So, the possible scenario is following: battery discharges down to 2.6 v, the device turns off, then the battery voltage goes up to 3.2 volts since there is no load.

    Am I right?

    I just checked the unit I have received and found that it has 3.2 volts cut-off voltage, not 2.6 as written here. When battery level is below 3.2 volts there is zero at Vcc. That is very good since 3.2 volts is best cut-off voltage for battery I have.

    I still curious how that may happen.

    OK, replying to myself. This looks like SAW filter.

    What is inside this metal thing?

    Pretty sophisticated devices

    That is why credit card skimmer kit would be a great idea.

No public wish lists :(
