Like a dummy i did not seperate my new batterys there the ryobi 18 volt batterys. Is there a fast way to see which batterys are in the best shape?
Some brands date stamp them also, that is date of manufacturing but that isn't necessarily a way to know for sure.I’m guessing that you can’t tell the old from the new.
most tool batteries have serial numbers on them. You should at least be able to
figure the production order by the numerical sequence.
Thanks don’t know of any way to actually ch cl capacity without taking them apart.
That may work but there may be varying voltages enough that it may take longer to notice any discernible difference.Assuming that there is no way to tell the old from new by looking at them (same markings and no scuffs or scratches on the old ones), you can charge them all up and check their Voltages after charging and after a week or so to compare self discharge.
