OSTC 2TR battery problem?

Post by silver111 »

So far I have had no problem with my OSTC 2TR computer and its battery (permanently installed).

Yesterday I was diving and started diving with 27% battery. After several dozen minutes, the computer turned off and it could not be turned on. Normally 30% of the battery should be sufficient for 2-3 dives. The computer, however, without warning, shut down.

After connecting the charger at home, the computer asked if a new battery had been installed and asked to choose. I chose option 1 - the battery is what it was.

Maybe I have the wrong type of battery set in the menu?
OSTC 2TR 16906 computer 3.16 - T0 battery type?

Please let me know what could have been the reason for turning off the computer?
I have never dived below 30% before but I did not see anything extraordinary about it because so far the battery has dropped by 2-4% for 1 hour of diving.

in the range of 30-99% everything is ok. The battery level drops slowly during the dive.

Hi,

Setup from the Reset menu -> Reset battery to the correct T4 type and recharge the unit overnight as recommended in the manual, Page 44:

For all OSTCs with rechargeable batteries
(OSTC2, cR and OSTC plus when using the
recommended 3.7 V LiIon battery), the OSTC
must be fully charged after each reset/reboot,
restart after an empty battery or insertion
of a new battery (OSTC plus only).
The displayed battery capacity (in percent)
is only correct when the OSTC has been
charged until the battery indicator was
highlighted in green during charging. Depending
on the model, this can take several
hours.


Note
If the battery of the OSTC was discharged,
the OSTC should be charged overnight (at
least 6 hours), regardless of the percentage
value displayed. It is important to set the
correct battery type in such a case, even for
OSTCs with a permanently installed battery.

Regards,
Matthias

Hi.

I did as you wrote above. I did a battery reset in the menu and then charged the computer for 8 hours. in the morning the situation was like this: the battery percentage shows yellow then green 100%. the charger lights up green and when the indicator turns green on the computer, the charger LED goes out for a moment. anyway, see what it looks like - I recorded a video. should it be like that and is everything okay now? ostc2tr battery type T4.

it is the same on the 2A USB charger and the xiaomi powerbank
