Laptop battery is a battery, control circuit, such as loading / unloading system components, while the quality of batteries for laptop battery overall effect is greatest.
Battery Battery, generally people speak 4CELL, 6cell refers to the number of batteries in the battery.
Currently the majority of notebook batteries computer are based on industry standard batteries, generally divided into two kinds of cylindrical and square. Cylindrical-shaped batteries in the battery a little bigger than 5 (see text of the first picture), while the square of the size of the batteries is roughly equivalent to the size of a Zippo lighter.
Parameters to determine how the battery is more carrots?
The current capacity of the mainstream of batteries: cylindrical for the 3.6 ~ 3.7V/2000 ~ 2200mAh, for the 3.6 square 3.7V/1800 ~ ~ 2000mAh for the battery in the end use of the number of batteries can be deduced from the above figures, such as the IBM ThinkPad T40/T41 standard battery 10.8V/4400mAh, then it is the number of batteries 6, using a chain of three, and two ways namely: energy saving three core series to 3 X 3.6 = 10.8 V, the two sets of series After the dell inspiron 6400 battery in parallel, then get 2 x 2200mAh = 4400mAh.
The IBM ThinkPad T40/T41 increase 10.8/6600mAh battery, then the number 9 on the batteries, using a chain of three, and three ways, namely: energy saving three core series to 3 X 3 6 = 10.8 V, the two groups once the batteries in series and then parallel 3 x 2200mAh = 6600mAh.
Generally speaking, the greatest expansion of the difference between the battery and the standard battery is that increasing the number of batteries connected in parallel to increase capacity.
Globally, the theory of laptop battery should be used in digital cameras and rechargeable batteries almost. The number of batteries in a single volume the higher and its battery life.
The practical application of theoretical knowledge
For example, the brother bought this TPOS R51 laptop battery, the rated capacity greater than 7200mAh, Voltage: 108000mV, the number is 9-cell batteries. Three sets of three, and in accordance with the model, you can calculate the dell laptop battery capacity 3.6V/2400mah.
Certification of laptop battery:
In addition, the laptop battery behind the label has a number of regulatory safety certificates, usually after a bit, the next figure (Sony laptop battery original) as indicated.
1, CCC certification: CCC certification, which means “China Compulsory Certification”, the English name “China Compulsory Certification”, abbreviated to CCC. CCC certification mark of “CCC”, the National Certification and Accreditation Administration Committee in accordance with “Administrative Regulations for Compulsory Product Certification” (The People’s Republic of China State Administration of Quality Supervision, Inspection and Quarantine Order No. 5) developed.
2, CE certification. CE mark is a registered safety certification is considered the manufacturer of open and entered in the passport of the European market. EC on behalf of European unification (Conformité Européenne). Any affixed with CE mark products can be sold in member countries of the EU, not required to meet the requirements of each member, thus achieving the goods in the states of the EU in the framework of free movement .
In the EU market, “CE” mark is a registered certification required, either in the EU production of goods or products from other countries to free movement within the EU market, must be affixed to the CE mark indicating that the product in accordance with the “EU coordination and standardization of the new approach” Directive on the basic requirements. It is a product manufactured by Community law a mandatory requirement. The Member States of the EU must be based certification bodies can issue certificates.
3 other (environmental certification of generality)
Abstract: In mobile authentication options above, if the words behind the preferred option for CE certification in May, after all, rigorous testing in Europe for electronic products in China more powerful than some see (personal) course and if not, CCC certification is required,dell inspiron 9300 battery,dell inspiron 9400 battery.
