OSTC 2 2017 : Battery
Posted by: aquarat ()

If the battery on the OSTC2 2017 is completely emptied, the "New Battery" menu is shown when the device is placed on the Qi charger.

Is the battery type "Internal 16650" / Type 4 ?

Is this battery user-replaceable or is it potted in resin ? I'm just curious.

What is the maximum/fully-charged voltage of this battery ? It seems to be around 3.9V.

What is the minimum voltage of the battery (the voltage at which the battery stops supplying power) ?

Thank you

Hi,

It's potted but replaceable (Not user-replaceable) and yes, T4 16650 is the type for the new OSTC2. Full is 4,1V but nominal voltage is 3,7V. So after a few hours of use the battery will stay at 3,7V. Battery percent is based on used charge, not on voltage in all newer OSTC. Battery is is protected by software-independent protection circuity against undervoltage and the battery is disconnected from the computer at ~2,6V.

regards,
Matthias

Bonjour,

j'ai rechargé l'OSTC 2 avec l'induction, la tension est bien de 4.1v

MAIS il indique en rouge: 0% chargé

Comment remédier à cela?

I suspect that once you have recharged the battery you will have to reset the battery status by using the battery reset menu :

Settings -> More... -> More... -> Reset Battery -> New Battery -> Internal 16650

And thank you for the information Matthias.

"T4", 16650 is the right choice yes, but you don't have to set it on every charge. It's _may_ required to be set in rare cases after a firmware update only.

Matthias
