Thanks Yuriy.
Your comments prompted me to do some research.
The current is very low - somewhere around 1.2mA and by removing the jumper that controls the green element of the multi colour LED it can be reduced to 660uA. Although that doesn't sound much an AA battery apparently has a capacity of about 3000mAh giving a life of about 3 months.
I would like to do better that and I measured the current with the data lines disconnected and it reduced to 36uA which would be much better. I was wondering about automatically disconnecting the data lines and I was thinking of using a 74HC08 to do it.
What do you think.
Thanks.
Russell
