Although lithium-ions have provided us more additional functions, it seems that lithium-ion laptop battery has brought us more potential dangers according to its features. When we criticize the manufacturers about battery accidents, we just haven’t really considered about how much potential safety hazard exists in it.

Looking back into history, we can see that Ni-mh and Ni-cd are far away from what we required from lithium-ion laptop battery. Whether in capacity, charge time or shelf life, lithium-ions have really given us a lot of convenience and efficiency to our work and life. With high energy density, laptop has become a real member of portable electronics instead of only changes in size.

As a rechargeable battery, Toshiba laptop battery can last for nearly two to three years by average. Even if only one-year warranty is available to users by free when purchasing, lithium-ion laptop battery lifespan should be determined by recharging cycles which is related with its capacity. However, with time goes by, more internal resistances emerge inside the cells and other circuits, which will cause overheat or overloaded.

There’s no denying for laptop battery that in the process of power supply, electricity energy is produced from lithium cobalt oxide, lithium oxide or other materials in electrolyte. Especially before nanotechnology has been used, pure lithium is very reactive, which may lead to explosion inside the cells. If it were not for hydrogen gas and lithium hydroxide inside, pa3399u 2brs will be at risk of serious accidents like electric shock or fire.

Therefore, it is really not easy for lithium-ion laptop battery to be so stable and durable as we expected. When Toshiba laptop battery becomes to be with higher energy density and output power, we should pay more attention to its performance and security when purchasing a new replacement pa3399u 2brs.
