LiIon Battery Characteristics
Sep 03^rd, 2009, 10:08am

Hello All,

I am trying to obtain information on LiIon battery characteristics. More specifically:

1. What is the healthy voltage range ?
2. What is the lowest Voltage below which there is effectively no life left in the battery.
3. What can be assumed to be the safe turn on voltage ?
4. Battery impedance relation to charge.

I need this information and more to design a POR for supporting LiIon batteries.

If anyone can provide such information will be greatly appreciated.

Look at the INtersil battery product line for chip specs, as a starting point.
