Strange battery voltage on 2N

[plut0nium]

Hi,

I own an OSTC 2N for a few months now (#5008), running with firmware 2.50.

Looking at battery status today (display voltage instead of battery icon, CF31), I get realy stange value for battery voltage: 4.68V
This seems very high for a Li-Ion cell to me.

Is this a software bug ? and ADC error ? or will my OSTC explode shortly ? ::o

Thanks,
Ch.
