<h4>The composition of laptop battery</h4>

Laptop battery is from batteries cells, control circuits, such as charging and discharging circuit components, while the quality of batteries for notebook battery the overall effect is the greatest.

At present the majority of notebook computer batteries are based on industry-standard batteries, generally divided into two kinds of cylindrical and square. Cylindrical-shaped batteries batteries bigger than 5 size, while the square of the size of the batteries is roughly equivalent to the size of a Zippo lighter.

<h4>How to determine the number of battery cells?</h4>

The current capacity of the mainstream of batteries: cylindrical for the 3.6 ~ 3.7V/2000 ~ 2200mAh, square for the 3.6 ~ 3.7V/1800 ~ 2000mAh, so the battery in the end use of the number of batteries, can be inferred according to the above figures, such as the IBM battery ThinkPad T60 battery and thinkpad T61 battery 10.8V/4400mAh, then it is the number of batteries 6, using a three-string, and two ways, namely: the three energy-saving core series to be 3 X 3.6V = 10.8V, the two sets of series after the batteries in parallel and then get 2 x 2200mAh = 4400mAh.

The IBM battery ThinkPad T40 battery and thinkpad T42 battery to increase battery 10.8/6600mAh, then the number 9 on batteries, using a three-string, and three ways, namely: the three energy-saving core series to be 3 X 3.6V = 10.8V, the two groups after the batteries in series and then parallel to be 3 x 2200mAh = 6600mAh.

Generally speaking, the greater expansion of the difference between battery and standard battery is that an increase of the number of batteries connected in parallel to increase capacity.

Overall, the laptop battery theory should be used in digital cameras and rechargeable batteries(thinkpad t60 battery,thinkpad t61 battery) almost. The number of batteries in a single volume the greater the more its long battery life.

<h4>Laptop battery Certification:</h4>

1, CCC Certification: CCC certification, which means “China Compulsory Certification”, the English name “China Compulsory Certification”, abbreviated as 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 safety certification mark is regarded as the manufacturer to open and entered the European market passport. CE on behalf of European unification (CONFORMITE EUROPEENNE). Any affixed with “CE” mark of the product can be sold in the EU member countries, not required to meet the requirements of each member, thus achieving the commodity in the EU member states within the scope of free circulation.

In the EU market, “CE” mark is a compulsory certification mark, whether within the EU production of products, or products of other countries, in order to free circulation in the EU market, must be affixed on the “CE” mark to indicate product in line with the EU “technical coordination and standardization of the new approach” directive basic requirements. This is a product made by EU law a mandatory requirement. EU member states must be based certification bodies can issue certificates.

3, other (environmental class certification) Summary: In the notebook authentication options above, if the words behind the CE certification preferred option may, after all, Europe’s stringent testing of electronic products in China stronger than some (personal view), of course, and if not, CCC certification is required.
