WILLIAM T about one year.
GEORGE T From Wikipedia - The most common consumer grade battery, about 80% of the lithium battery market. Uses inexpensive materials. Suitable for low-drain, long-life, low-cost applications. High energy density per both mass and volume. Can deliver high pulse currents. Wide temperature range. With discharge the internal impedance rises and the terminal voltage decreases. Maximum temperature limited to about 60 ?C. High self-discharge at high temperatures.
I would expect a decent shelf life since I have used the original battery in my Sol for about 3 years and it is still functioning. However, I do see some signs that the battery is loosing some of its power. Hence, about a year ago I bought a back up just in case.
EDMOND J Well, my experience is with one battery. I put it in my computer last Summer and it was about 2 years old then. It showed up as full on the computer at that time so I would think at least 3 years. (It is about 1/5 used now). I really should get another one just to have one in case I need it.
