The internal structure of laptop batteries an

• The internal structure of laptop batteries

Notebook computer Dell inspiron 6400 battery are generally made of the shell, battery, charge and discharge control and protection circuits (to prevent over-charging and over-discharge), etc..

Talk about battery pack as a core component of notebook computer akku . General laptop battery is 10.8V or 11.1V, and a single cell can not meet the requirements of notebook PC batteries and are based on so many single cells in series and parallel component of the battery pack (pictured is the use of two sets of three parallel and in series after the to form a battery group). As we often see in the Sharp md-mt831 battery shell of 3300mAh, 4400mAh and so refers to the capacity of the battery, which is indicative of the current on the battery discharge can be used for one hour, for example: 4400mAh lithium battery can discharge current 4400mA for one hour . Therefore, the value the bigger the better to prove it can work longer.

To charge and discharge control and protection is responsible for the Casio np-100 battery charge and discharge control and protection, and it works principle is that, because the lithium battery in the charging process is very close to the full voltage will drop slightly 1:00 pm Therefore, this control circuit to detect a situation that when the battery is already full, and protection circuit is also working to cut off power supply in order to prevent overcharging; discharge the battery voltage is basically stable and unchanging, the remaining battery power only rarely, when a sudden drop in only, when the control circuit detect this situation is that the battery for Jvc bn-vf808 power ran out and inform the protection circuit cut off power supply to prevent excessive discharge the battery life shortened.

• battery DIY

Because the current laptop battery prices(such as Dell vostro 1500 battery )are generally not cheap at between 600 to 2,000 yuan, the price can be described as stubbornly high, many often have to use the battery notebook users a headache. In fact, a battery life does not mean the end of the battery completely useless, because the general is just its internal battery pack or failure caused by aging, while the circuit part of the generally intact so long as you are willing to play about the spirit of DIY you can save not little money.

It can be sure to have a little physical knowledge and bold but cautious ,when you replace battery for Jvc bn-vf823 pack by yourself , that is to dare to open the battery hands, hands they need to be careful not to damage the circuit or else you do not want to buy some of the new Du Bu Xingle. In fact, this is very simple, in the post-open the battery cover you can see the internal battery pack and circuit, when you carefully look at your Samsung sb-lsm160 battery pack and parallel mode (what? You do not know how to look.) and the use of battery type, model and number, about these after going to buy back the battery electric market, the battery needed to monomer, and a lithium battery monomer is generally 20 to 35 yuan. Buying the battery monomer should be noted that simply have to buy the same brand, same model, same batch of products, because the experiments show that a number of battery strings in parallel when using the battery for Canon nb-71 ,due to subtle differences in monomer monomer will advance to a battery failure thereby affecting the work of the entire battery pack, so be sure to note.

After buy Fujifilm np-95 battery back,it is necessary to take off the old battery from the battery group, one by one electric soldering iron down, and then go back to new as is welding, but to remind what is the electric soldering iron temperature should be high, so that the welding process can be used a very short period of time and battery contacts, or a result of high temperature Ershi shortened battery for Jvc bn-vm200 life and performance. Finally the case with the 502 like the glue seal is good, loaded back on to test if the laptop is no problem, then congratulations you're done!

How temperature have impact on notebook battery

When using mobile , the battery decided to notebook life, as the too high or too low a temperature will bring a variety of problems for laptop with a lithium-ion xps m1730 battery , in the non-normal temperatures,then how the temperature affect the laptop battery?

1. 0-40 ℃ is the most reasonable working environment

it have an impact on using notebooks, such as the humidity, static electricity, temperature, and so but the lithium-ion Dell xps m1330 battery on the temperature is most sensitive to high or low temperatures, too high or too low a temperature will have negative impact on normal circumstances the battery, Lithium-ion battery limits of the ambient temperature is -20 ℃ ~ 60 ℃, while the 0 ℃ ~ 40 ℃ was the most reasonable working environment, but should play a laptop batteries performance potential, 20 ℃ or so is the best use of the environment.

2. -25 ℃ below will affect the battery life

Although the laptop battery allows -20 ℃ environment, to use, but this will be the battery charge and discharge performance impact is very large, usually, the ambient temperature, the lower, the vostro 1500 battery inside the active material of the activity the lower the electrolyte resistance and viscosity The higher the ion diffusion more difficult, the battery charge and discharge is not easy.

For example, when the ambient temperature is below zero, the battery charge-discharge efficiency will be greatly reduced, thereby charging rate will be very slow, full of power after the power of time and only had about 60%, when the ambient temperature falls below the minimum temperature limit (for example, -- 25 ℃), the battery for Sony np-fh100 electrode reaction rate is very low, the electrolyte may even consider freezing point, the battery performance may be only 10 percent, seriously affecting battery life.

3. 60 ℃ and above may explode

With the low-temperature case, if the laptop battery ,Sony np-qm71d is used in high-temperature environment, it is same to affect the battery charge and discharge efficiency and battery damage is more serious, such as the use of low-quality charger or the charging time is too long to make the battery heat large, when the charge temperature exceeds the maximum limit temperature, it will destroy the battery for Fujifilm np-95 within a chemical balance, causing the battery to the material performance degradation, the battery life reduced.

By the same token, the battery during discharge time, that is we use the notebook, because of the battery internal short circuit or Nikon en-el8 battery design flaws, if the temperature exceeds the maximum limits of battery capacity decline in life receded, serious situation will have seen an explosion, burning and other accidents.
