Just wondering what the typical initial voltage is of a new aa or aaa nicad battery before the first time you charge it. I just bought some and the voltage ranges from .9 to .99 volts which seems too low to me, I know it is very bad to let batteries full to this voltage normally but what about when they are brand new, are these voltages ok then,as anybody else measured the votlage on new batteries before charging them for the first time. I wonder if the ones I bought have been on the shelf too long.
what is typical voltage of new nicad?

May be fully discharged. New NiCds don't mind being near 0 V.

There's nothing wrong with discharging nicads all the way. The problem is with batteries (cells in series); there will always be one cell weaker than the rest and when it gets discharged to zero, it'll then get charged in reverse from the others ramming current through it.
I was once told that NiCd batteries should come fully discharged and have a much longer shelf storage versus once they receive their initial charge. I do not know if this is indeed true or not, but it seemed to make sense to me. I do know that fully charged and fairly new NiCd batteries will fully discharge on their own without any external current drawn over a period of
2-3 months.Bob
Thanks to both of you for those helpful replies.
They don't charge 'em cause the process time to do so would bring the production line to a crawl. There are probably other secondary issues. mike
