[Tfug] Source for notebook batteries?

[Jim March]

Don,

First, a terminology issue.  Each "cell" of a multi-cell pack is
capable of acting as an independent battery on it's own, in a
flashlight or something.  Therefore it's not improper to refer to each
"cell" unit as a battery as I've done at times.

Second, if you're replacing only SOME "cells" in a multi-cell pack,
you're doing it wrong.  Chain a weaker battery in series with a
stronger one and you run several risks - at a minimum you won't get
full performance out of the new battery(s).  You also don't have the
opportunity to replace, say, 2400mAh batteries with 2600 or 3000
rated, which IS possible if you replace them all at once.
