It's not at all straight forward. See http://focus.ti.com/lit/an/slaa287/slaa287.pdf

Mark,
None that I know of but weight wise wouldn't it be the same as
carrying three spare sets of batteries?
Or someone of this list could go green (maybe even get a govt
grant) and design a lite weight solar panel that one could unfold
and charge a battery.

Well just as an exercise in thinking out of the box, is there a
product
out there where you can say take the battery out of say a Canon
digital
SLR, where you can put the battery in the device and have it hooked
to a
regular lantern type of battery and have it recharge the battery for
your camera. The big 6volt lantern batteries come to mind but maybe
the
old 9 volt cells would work better. Yeah I know there are car
chargers,
but what can you use to recharge when you away from both power and a
car. Be real handy on a back packing trip or say when working some
event where you might need to recharge one battery while using
another.
Anyone know of such a product???
