Title: LiIon Battery Characteristics
Post by ic_engr on Sep 3^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.

4.3V peak, 2.7V minimum for single cell LI-Ion

the other questions are unique to the particular battery -
time to do some research and read both battery specifications and specs for battery controllers. Look at the INtersil battery product line for chip specs, as a starting point.
