How to The impact of temperature on the laptop battery

Although the laptop battery to allow use in -20 ? environment, but this will impact the battery charge and discharge performance of a great general, the lower the ambient temperature, the battery inside the lower the activity of active material, electrolyte resistance and viscosity The higher the ion diffusion more difficult, not easy to charge and discharge the battery.



For example, when the environmental temperature is below zero, the battery charge and discharge efficiency will be greatly Acer as07b41 battery reduced, so the charge rate will be very slow, full of electric power supply time after only about 60% of the original, when the environmental temperature is lower than the minimum temperature limit (for example - 25 ?), the battery electrode reaction rate is very low, even from the electrolyte freezing point, only 10% of the battery performance may seriously affect battery life.

Guangdong Xia on October 10, 2008 purchased the computer model, to December 2009 can only use the battery less than 5 minutes. Lenovo customer service on the computer's battery Xia was detected, said the quality of the battery no problem, but when asked Lenovo to show him Xia test report, the association said they can not be provided to consumers.

Liaoning Ip is the February 2009 purchase of the computer, in June 2010 issue of the battery suddenly, the computer shows remaining battery power and 90% of the time the computer is automatically shut down, plug in the power turned on the battery's remaining Acer aspire 5520 battery capacity was found only 4%.

Guangzhou Cheng on Jan. 31 2009 purchased the computer models, in May 2010 there have been similar problems, the battery can only use about 10 minutes, and in charge when the battery directly from the 50% Skip to 100%.

Shenzhen, Mr. Wong was March 14, 2009 to buy a computer, in April 2010 found that the battery problems, repair stations told him the battery is consumable, so he bought a new battery, Mr. Wong was very dissatisfied with requirements battery testing, test results are: no external power supply, power consumption, the remaining 30% in electricity alarm and automatically shut down and a range of up to less than 20 minutes. In the external power supply while charging the battery charged up to 40% jump 100%, obviously the battery, great loss, not the actual storage capacity.

Consumers just over four hundred representatives of consumers, and other consumer problems are very similar with the four above, are basically post with one year warranty on the battery when the problems mentioned above.

Many consumers also to the editors that they have a computer within the warranty period had already seen such a problem, Lenovo is happy to give consumers replace the battery, but as long as one period of insurance is simply nobody, and the replacement of the new Acer aspire 5920 laptop battery will appear the same problem.

These consumers associate manufacturers to reflect the problem, exactly the same response given by manufacturers association, said that because of consumer misuse leading to shorter battery life, and consumers that "Is the country so many problems because of consumer batteries caused by improper use of it? "Obviously, this argument is difficult to convince people.
