We have the following brief account of how the scientific use of their notebook batteries.

First of all, a popular practice in the use of electricity work for a long time, many users of laptop battery will discharge, so that can extend battery life. In fact, to ensure a good habit to use the premise of whether or not to unload the battery module to the battery life is not unduly affected. For users who do not discharge the battery, do not need to pay attention to the frequent power plug because of the short period of time appears to be inconspicuous Plug Power, will also have a battery in the charging and discharging process, the frequent charge-discharge operation will be shortened Battery life; and the battery will be on the side of the user, the best time to time (about a month or so), the battery will be carried back into laptop Sufficient, so as to maintain the best battery If the battery idle for too long, will lead to reduced capacity.

Secondly, lithium-ion batteries, there is no need to run out of electricity to charge again, this is because the lithium-ion battery is almost no memory effect. The so-called memory effect occurred in nickel chrome or nickel-metal hydride battery on the battery, which did not fully discharge the battery in the case, there would be some kind of crystallization of reaction, resulting in a temporary decrease in battery capacity, to eliminate this memory effect Can be done several full battery charge and discharge cycle, there are likely to come back to save the battery.

Another is the need to pay attention to the use of the environment, although the mobile computing experience a wide range of environmental, but at room temperature for the use of battery life to ensure that there are certain benefits, cooling the overheated environment of temperature on the laptop will be Harm. In addition, when using the transformer in operation, from the outside world on the one hand, the power supply will support the operation of the system, on the one hand, rechargeable batteries, so that the process of charging off than under the charge of the operation slow, fast if you want to charge, it would be better In the off manner.

Some users complained that some bring their own battery power display reliability is not high, in fact, the existence of these products in a special battery capacity computing chips. In general, notebook computer batteries, or the percentage of the show has a certain credibility, should be noted that from time to time, it is best to do the battery calibration operation to correct calculation of battery capacity chips possible error. Calibration work can be carried out in two ways: external power out, turn off power management in the power-saving mode, and discharge their own computer to shut down; the use of random or in the BIOS related software calibration.

In the mobile use of laptop battery life decisions, as the notebook with the lithium-ion batteries, in a non-normal temperatures, too high or too low temperature will bring a variety of questions, then the temperature is how it affected notebook battery?

1 ,0-40 ℃ are the most reasonable working environment

Notebook when in use, humidity, static electricity, temperature, etc. have an impact on it, but the lithium-ion batteries the most sensitive to temperature, excessively high or low temperature, the battery will bring negative impact to varying degrees, usually lithium-ion battery for the limits of the ambient temperature -20 ℃ ~ 60 ℃, and 0 ℃ ~ 40 ℃ is the most reasonable working environment, but to exert the potential of laptop battery performance, 20 ℃ or so is the best use of the environment.

Second, -25 ℃ the following will affect the battery life

Although the laptop battery in -20 ℃ permit the use of environment, but this will be the battery charge and discharge performance of a great Under normal circumstances, the lower the ambient temperature, the battery inside the actives activity the lower the electrolyte resistance and viscosity The higher the ion diffusion more difficult, not easy for battery charging and discharging.

For example, when the ambient temperature is below zero, the battery charge-discharge efficiency will be greatly reduced, thus charging speed will be very slow and full of electricity supply after the time and only the original 60%, when the ambient temperature falls below the minimum temperature limit (for example — 25 ℃), the battery electrode reaction rate is very low, even from the electrolyte freezing point, the battery performance may be only 10%, serious impact on battery life.

Three, 60 ℃ or more may be explosive

With the low temperature case, if the laptop battery in high temperature environment, which will affect the battery charge-discharge efficiency, but also for more serious damage to the battery, such as the use of inferior charger or charging time is too long, making the battery larger heat, When the charging temperature exceeds the maximum limit on the temperature, this will destroy the battery’s chemical balance, resulting in performance degradation of battery materials, to reduce battery life.

The same reason, the battery during the discharge time, that is, when we use the notebook, due to internal short-circuit the battery or battery design flaws, if the operating temperature exceeds the maximum limits, battery-powered ability, life receded, the situation will be serious emergence of the explosion, burning and so on.
