It simply means that section of bad batteries before charging full, discharge it first had finished, but this time the capacity of other batteries are not being fully utilized. Core of a saving over charge / over discharge will not cause the d620 laptop batteries   battery monitoring circuit that is full / End of release. For example, when charging other batteries began charging close to full pressure of time, that section of bad batteries may have to 4.30V or even higher voltage, resulting in overcharge damage, while others are fully satisfied.

Interest, courage and ability friends can try to open the battery pack, believe in the multimeter's help, you can quickly find the damaged batteries (abnormal voltage). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product. d620 laptop batteries
