I got a whole bunch for free, and the little light that says they're charging NEVER goes off. Will it hurt if they aren't all the way charged, or how long do they usually need to be charged???

all wrong. it totally depends on the type of battery , nicad, ect and the charger. trickle chargers take 8-12 hours. quick chargers take 3 hours. Never over charge your batteries it will shorten thierlife or ruin thm completely. The only way to be accurate is the get documentaion on your charger or use a volt meater to to test the voltage output to the batteries. example: when a 9v battery is fully charged it will actually read about 10.6-11 volts dc. when its at 50% it will read about 10 volts dc if your 9 volt battery shows 9 volts it is discharged and needs charged.

Since you got them for free maybe they are no good. It also depends on the battery. I have a pager for the fire department, I also have extra batteries, I leave them in there and the light stays on. The light showing the pager is charging is also on. The pager that I have uses AAA batteries. I wear it when I am not home and the batteries seem to last forever as long as I charge them at least eight hours for every 24 I wear the pager. I got a charger with a camera case once and I did not have too much confidence in that. Most reliable charges will shut down once the battery is charged.

I think I had some small ones that took 6 hours, but others may take a whole day. Perhaps something is wrong with your charger.

Usually between 12-24 hrs... Find the manual online, if necessary... Call Radio Shack...
