[AT] Digital camera batteries

[Larry D. Goss]

Not all rechargeable batteries benefit from a complete discharge before
recharging.  Many of the newer designs no longer suffer from the
residual charge problems of the old styles.  I have several chargers
that do the complete discharge routine every time -- old video cameras,
battery-powered drills, etc.  The newer chargers I have that are built
for the Li-ion batteries don't have the discharge cycle, and the
literature that comes with the hardware says that discharging isn't
necessary.

Even store managers can "get it wrong" if they don't keep up with the
changes in battery chemistry.  When in doubt, read the small print in
the flyer or on the blister pack that the batteries come with.

Charlie; I'm not positive but I think both of mine came from a small
Radio 
Shack store here in town. The guy that I talked to was the store manager
and 
he's the person who told me about the need for a full discharge BEFORE
each 
charge. These little chargers will charge either two or four batteries
at a 
time and have an amber light for discharging which turns to green on
fully 
charged batteries. (a light for each two batteries). The chargers are
small, 
about the size of a pack of regular cigarettes. Don't recall what they
cost 
but it wasn't a lot or I wouldn't have two of them.(g). That's the
dutchman 
in me.
