I bought an OSTC plus at the last Boot exhibition (Ser. No. 16425).
It works well, i love it.
But now I have problems with the supplied internal 14500 AA LiIon battery.
I recharged it to 100% (i like the inductive charger very much).
After a few minits of diving an alert comes up, "battery capacity only 3%".
But the computer keeps working, even over a 90 minute dive.
I have seen this during the last three dives.
What do you think, should it be a defect of the LiIon battery or is that another problem?
