Battery for notebook is important, a direct impact on the portability of laptops, so the battery test not only observe the appearance but also to use specialized software for testing. Some brands such as IBM, SONY are equipped with specialized software to detect the frequency of the IBM ThinkPad T60 battery charging, while the HP notebook can detecte charging times in the BIOS. Through these post-test software or BIOS, if you found the battery charged more than 3 times, then the battery is used, the user may require dealers to replace.
To the other brands can not detect the frequency of hp PB992A battery charging, we can through a special software to test - Batterymon. You need to install the software, the installation file is relatively small, only 400 KB.
Batterymon can detect the battery’s total running time (theoretical value), can detect the battery power, as well as the remaining duration, we should notice that the capacity of new Laptop battery should not be higher than 3%.
After finish testing these projects, the following click on “information” in the “battery information”, you can detect some of the specific information of the battery.
Here you should look out the data in “design capacity” and “full charge capacity” columns are the same or not, for a new Dell Inspiron E1505 battery, the design capacity and full charge capacity should be the same. My notebook had been used over half a year, there are differences between the fully charged capacity and the design capacity is a normal phenomenon.

For the high incidence of various types of notebook computers caught fire, explosions, industry experts said that the notebook computer batteries overheating caused fire and explosions occurred at home and abroad constantly.
The fierce competition in the market to force notebook makers to seek ways to lower the costs, while the notebook computer once with the “bad” battery, easily lead to overheating, fire phenomenon, and even greater accidents and losses.
So, when using a laptop, user should how to avoid an explosion incident? In this regard, experts said, consumers need not be over worried about the Laptop battery, most of the brand notebook computers are able to ensure safety. User should take preventive measures, to pay more attention in the following areas:
First of all, we must choose well-known brands of products, and check on manufacturer related qualifications.
Secondly, always pay attention to maintenance of the Dell Latitude D800 battery, do not covet a moment to choose a cheaper second-hand battery.
Finally, the laptop loaded the battery and at the same time connected an external power source may happen dangerous. Therefore, as far as possible to avoid using the notebook on a soft cloth, sofa and so on, and do not use directly on the legs, do not let the hp F4812A battery overcharging to avoid overheating batteries cause a risk, if necessary, match a special cooling pad.

Why Laptop batteries are also consumed after laptop turned off and cut off the power supply?
The appearance of this phenomenon is due to the characteristics of a computer, please check the following reasons:
1. After the computer shut down, the laptop battery will provide power for RTC functions.
2. The power switch is not only the power line switch, but also power supply switch of the control management, the signal sent to the power switch function.
That is, the management of the power supply controller connecting the Dell Latitude D410 battery and power adapter alway in a galvanization state, so there are electricity consumption.
The run of micro-computer circuir even send a message will consume battery power.
VAIO batteries, not just the battery, but also added built-in micro-computer to monitor the battery status (battery remaining capacity and charge and discharge current value, the temperature of the battery group, etc.), and at regular intervals send a signal to the computer functions.
Therefore, the hp Pavilion dv4000 battery loading in the computer will definitely consume electricity, even put out there will be electricity consumption except natural discharge. Thus, even cut off the power supply, battery consumption is normal.
