Care and Feeding of Lithium Ion Camera batteries

[Mike]

Hi, I recently bought my first digital camera, Olympus C-7000 Z, and spare
battery.
The Olympus lithium ion battery is part #Li-12B the spare lithium ion
battery is Digital Concepts BP-Li12B.
According to the Digital Concepts battery packaging it's a 1300Mah battery.
I believe the OEM battery
is rated somewhere around 1100Mah. The spare battery rated at1300Mah damage
the camera?
Should I keep the batteries charged or let them run down?

Any suggestions for keeping the batteries in top shape and extending their
life,
Is this the correct news group to post this message?

Thanks,

Mike
