Now, not only laptops of different brands of batteries can not be General Motors, together with the brand, different models of cell laptops, it is hard to be generic. laptop battery, “exclusive”, so that consumers will indeed buy a new cell laptop that was a waste of time.
It is understood that the laptop battery life is not the time to calculate, but according to the number of battery charge and discharge of their operational lives. laptop nickel-hydrogen batteries used in general can be 200-300 times charge-discharge, lithium-ion Hp 342661-001 battery charge and discharge is generally 350-700 times. According to a survey conducted in March shows that most of Shanghai’s laptop users to replace the laptop for 1-2 years frequency. The industry is estimated that under normal circumstances, after the user change the laptop, original laptop batteries can continue to use for a long period of time.

In this regard, the explanation is that cell laptop manufacturers for different consumer groups, tailor-made products have a personality.
