Re: [Phys-l] lithium batteries



According to these people, lithium-ion batteries are best stored at 40% charge:

The newer A123 lithium nanophosphate batteries are best stored at higher levels of charge, about 95%.

The A123 cells are fantastic: best cycle life with highest discharge and charge currents. I built a cyclemotor that uses them:

Who stores all of his alkaline and zinc/carbon batteries on the fridge shelf, where they last at least twice as long. See Fig 14.2.E in Horowitz and Hill's "The Art of Electronics."

New to me. I'll query the PHYS-L crew

According to the Canon instruction book, a lithium battery wears
itself out by being charged. they recommend DISCHARGING a battery and
then storing it (when for a long time) and charging it the day of use.
Just the opposite of Nicads.
