The battery to my Sony camcorder (battery model NP-F330) has gotten to a
point where it's no longer usable. FYI this is a lithium-ion ("InfoLithium")
type with about 90 minutes capacity. When it was new, it worked great, the
time remaining counter was accurate right to the minute. Over the years, it
got so it would show the low battery warning (and shut down shortly
afterwards) long before it was supposed to. Now at five years old, it runs
for a maximum of five minutes on a supposedly full charge. Is it time for a
replacement, or is there any way to "rejuvenate" it?

You are going to have to replace it. This rejuvenation thing does not work
well.

The batteries work with a complex chemical reaction. There is a fair amount
of chemistry involved. Basically the structure of the battery wears out. The
chemical change is not reversible.

The expected life is about 3 to 4 years. Over that period you should get
about 1000 maximum charge cycles out of any of these batteries. Whether or
not you use a battery, it will eventually degrade, and have to be disposed
of.
