OSTC2 battery issue (drop off power. lack of internal battery)

[MaliC]

Guys,
I can't find on forum.
Anybody can help?
OSTC2, fully charged (after 12h of charging) shows full battery (99%). In two hours I'm starting diving, and I have 0% of battery. I can easily do dive, as I do for 3 days with such alert with 0% on my computer. I reboot, reset battery, for one dive is even 100%, then 85%. When I do battery reset, sometimes I have T4 - internal battery, but some times I can't choose such option.

soft 3.12 HWOS, same was on version 3.01 (my previous upgrade).

Thanks,
MaliC

Hi Malic,

Where did you find release 3.13, the latest available on the web site is 3.12 ! Or maybe you talk about legacy OSTC's (Mk2, 2C, 2N) ? In this case, you're not on the right forum...

Best regards.

You're right. 3.12. My bad. Edited above.
