Sanwa Gemini Battery problem..

[chris_exeter]

I've just bought a brand new Sanwa Gemini II transmitter howver the battery seems to die VERY quickly.. from what I have experienced so far in practise I just cannot see the transmitter lasting for a whole meeting.

Is this normal and do most people have two fully charged transmitter batteries or do you think there is a fault in the transmitter battery?

Thanks in advance!
