Where can I find data or a web site on batteries in general.  I'm looking to
spec in a battery to power a Pic and a bunch of other electronics for about
20 hours.  The current consumption of the parts would be about 300mA/hour.
What would be the ideal battery?  Also can anyone direct me to some
companies that do fast charger IC's as well as gas gauges for batteries.
And any parts that you may recommend.

Thanks
DW
