Matthias, thank you to tell me if it is possible to explain what happened with the first and the second battery,
[left][/left]
- How is it possible to test the battery capacity, not just the voltage?

- Why Diving Total : 49605 on my logbook?
[left][/left]
- Why my logbook is emptied? My OSTC3 was connected to my PC.

For info, already reported on a topic of Yeti42, I don't find very making safe from a mechanical point of view to have only one net of threading of just one turn on the battery lid for a diameter of approximately 12 mm
The lid's threading which is an important point for security of the sealing of the OSTC3 will deserve to be improved,

What do you think for this point, can you do an action on this issue?

Thank you in advance for these responses, Regards.

Hi,

Looks more then a hardware issue to me, this has nothing to do with the firmware 1.41, sorry.

Can you please contact us directly: info@heinrichsweikamp.com ?
