do sys 11 go through batteries quicker than other machines? cos my sys 11 games seem to go through them twice as fast as my old gtb and ss bally
That's strange, are you talking about both of them or just 1?
I have had my swords of fury for a few years now and only change the batteries once every 12 months, and they are still at 1.5 volts each when tested after i remove them.
If it is just one then it could have had the ram replaced with the incorrect type or a faulty diode on the cpu board. Or the batteries could be nearly dead when you install them.
