Re: Battery Voltages

[Steven Trovato <strovato@optonline.net>]

There is no hard and fast rule.  I don't save batteries that test lower 
then their "advertised" voltage.  That is, less than 9V for a 9V battery, 
or less than 1.5V for most everything else.  For some uses like smoke 
detectors, I will only use new fresh batteries.  For others, like kids toys 
that are likely to be accidentally left on, I'm much less concerned.  If 
the robots eyes only blink for 4 hours instead of 8, I can live with that!
