Charging a rechargeable device
Neo’s rechargeable batteries use Nickel Metal Hydride (NiMH) cells.
NiMH cells can be charged about 500 times. Fully charged batteries
can power the Neo for 60–150 hours (or even much longer),
depending on use. (Note, however, that fully charged batteries that
are never used lose their charge in about a month due to the self-
discharge effect.)
