Default Voltage chart for nimh ?

Is there a voltage chart anywhere which shows the remaining charge percentage for 24v nimh batteries ?
If not, does anyone know roughly what voltages they should read from full to empty ?

Full tends to vary according to the charger, but a safe full reading is from 1.45 to 1.5 volts per cell. The danger level is 1.55 volts

Empty as far as usefulness is concerned is about 1.2 volts per cell, their nominal voltage

They can be taken down to about 1.05 volts per cell, but at below 1 volt damage can occur.

Cheers Flecc.
That all seems to tie in with the readings I'm getting from my multimeter and the indicator lights on my bike with full being around 28.5v and empty around 24v.

That's perfectly normal. When brand new a 24 volt battery will charge to a bit over 29 volts, but soon settles below.
