With the shape of the vastly different notebook computers, batteries to cater to its shape change, there are rectangular (like bricks:)), cylindrical type. Since the Sony laptop  battery there is this difference, so they can not be universal, and sometimes even the same family are not into. Such as the IBM X2 and the X3 series. Moreover, many placed the location of the battery are also different, and sometimes can be done when the notebook’s feet with.

The size of the pool size is directly related to the use of laptop time. Its size mainly from the marked mAH battery mAh) and voltage multiplying the results of a few volts to judge. Battery life is not solely determined by the capacity of the sony VGP-BPS2  battery with the use of the environment and hardware configurations are closely related, and how many batteries are also related to the general number of the battery core 4-6Cell, batteries of the same Under the batteries more than the capacity of the battery, the more natural, less batteries, the battery capacity of the naturally less. That said, the battery capacity, we have to look at some additional features battery. If you are Samsung or a DELL laptop user, you may notice that their battery will have a row of small lights, when the press next to the push button, a small light will stop blinking, you may not think that this is only a battery ornaments It is a role is used to display the sony VGP-BPS2B  battery capacity, it comes from the first creative player. Some low-cost LCD display Walkman absence of windows, so we used the same methods with which to display the remaining battery capacity, which do not boot, remove the battery capacity will be able to understand the function, I feel very convenient. Now only DELL (L400-era began), Samsung and other models used a small amount of this approach.

In addition, we should not ignore the weight of the sony VGP-BPS2A  battery, which directly affects the laptop’s overall weight. Ultra-thin machines generally small in size and the battery would be more, rather than the relatively large number of mainframe, which will be more on batteries, such as the above to see a full range of IBM battery.

laptop battery from 3 to 6-pin or 8-core-core, from 23 to Qi Babai hundred or even thousand dollars, usually normal use of the life in two years or so! This notebook computer users is a big loss!

If we can designed a notebook computer plug-in battery pack, you can use regular V battery-powered, it will be a good choice!

This battery box, there are two design ideas:

1 may be based on different models of dell C1295 battery is designed to correspond to the size of the laptop when necessary to replace the proprietary batteries, open the box, you can put a specific amount of 5 batteries.

2, can be designed into a real plug-in batteries, is equipped with the same laptop power adapter plugs directly into the notebook DC power interface.

Laptop DC voltage is generally between 12v to 20v, current at about 1.5a. General six-cell battery power in the 4800mah. General 5 batteries (rechargeable type) voltage of 1.2v, city, price of 16 yuan a. This is equipped with 10 such as rechargeable batteries, also 160. Even if the life expectancy, replacing them can accept! More importantly, such a dell GD761 battery is readily available to sell! If we are in special circumstances, but also with ordinary non-rechargeable batteries temporary spare!

By design, the only technical difficulty is the battery box must be configured to current control circuit (chip) that can provide the necessary stability for notebook current! It takes another configure a dedicated charger, or directly converted to use laptop power adapter comes with charger!
