- More than likely, if the manufacturer tells you that you shouldn't fully
- discharge your batteries, they aren't NiCd batteries. The NiCd should be
- fully discharged before recharging again. However, and this may be what
- the manufacturer was really warning against, they shouldn't be DEEP-
- discharged. What happens, as I understand it, is that when you have more
- than one battery in the battery pack, you get reverse charges, and that
- destroys the batteries. There are some ways to bring them back to life,
- but they are risky and have very low success rates, and I don't even know
- what they are. Your best bet is just to bite the bullet and buy a new
- battery pack, and chalk it up as a learning experience.
