A very old memory, here. Nicads used to be shipped some how
factory discharged. You'd have to leave em on charge for a
full day, and then use them. They shelf life for many years,
with the factory "setting".

I bought them new, but they may have already sat on the
shelf for months,
right?

Most all battery chargers have a light on it that indicates charging status.
Do you think that if it takes 8 hours to charge a battery that the battery
using public will put it on a charger, and then stay up for eight hours
until the wee hours in the morning to shut it off? No. They have an
automatic shutoff that will stop charging when it gets fully charged. Same
with cell phones.
Think about it. If this was a big problem, we would have heard all about it
by now with exploding batteries or burning houses.
Yes, NiCd are bad about memories. But the thing that causes memory problems
is if you partially discharge it, and then charge it, that is where it
develops memory. I have used a rubber band on the trigger to keep it on and
drain the battery completely. Use the thing until it just won't turn a
screw or even turn with your hand holding the chuck, you want it to be that
weak. And next time, buy a NiMh battery drill, which you can recharge at
any state of depletion with no memory effects.
If you have doubts, call the cell phone provider and see if your phone is
one that needs special treatment.
I'd say no.
