1, Overdischarge, overload and short circuit protection.

2, The single battery possibly endures overcharge and overdischarge though the battery pack operates at normal voltage range.

3, It indicates the battery terminal voltage when the overdischarge protection started and the fire emergency luminaries can't play the role of emergency.

4, With reasonable power management, overcharge and overdischarge can be effectively avoided and the service life of lead acid battery increases.

5, Do not mix new batteries in use with semi-used batteries, overdischarge may occur.

6, Bus voltages greater than 100V preclude the use of a standard IC for overcharge and overdischarge protection.

7, The capacity of battery suffering from PCL could be restored to the normal level by both high temperature method and reverse charging after overdischarge,(http:///overdischarge.html) but it decreased quickly during cycling.

8, In this paper, the design of single chip of lithium-ion battery protector is discussed. Protection includes preventing overcharge, overdischarge and overcurrent states in the lithium-ion batteries.

9, SOC system can not only avoid the overcharge or overdischarge of battery, but also play as a important role as auto gas instrument.

10, When find battery power down during use, please switch off the device to avoid overdischarge.
