The composition of laptop battery

Laptop battery

Use rechargeable batteries for notebook computers is relatively one of the advantages the desktop, it can greatly facilitate the environment in a variety of laptop use. Introduced the first battery is nickel-cadmium battery (NiCd), but this battery has a "memory effect", each charge must beDell original inspiron 1525 Battery discharged before, very easy to use, soon to be nickel-metal hydride battery (NiMH) are replaced, NiMH is not only not "memory effect", and the weight per unit can provide 10% more power. The most commonly used battery is lithium-ion battery (Li-Ion), it is no "memory effect" compared with NiMH, get more weight per unit of electricity prices twice as high than the NiMH.Dell inspiron 6400 Battery Under the same weight, the three battery is 1:1.2:1.9 ratio. There is also a battery called polymers, very high capacity, small size, most used in Apple Computer. Currently the batteries used in notebook computers are three main points: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; them generally expressed as: Nickel cadmium NI-CD, Ni-MH NI-MH, lithium LI. Purchase or replace the battery when the laptop for many users, the "batteries" may be unfamiliar. At the outset, batteries and battery are two concepts. A battery is slightly larger number than the thumb, cylindrical, about 7-8 cm high, voltage 3.6v small units, professional, it is called is called 18650, Sanyo and Samsung is the largest producer. Batteries like a small battery, in series combination, we see that the battery was. Then talk about how to judge the battery is several cores: one way: unplug the battery number of contacts to see him, there is some core of a few. But it is the "minister" means. We take a look at "Cao Chong" is how, Hp dv1000 Battery "said as" follows: take a look at the nominal number of your battery v, such 14.4v, then divided by 3.6 by 4, then proved to be four batteries together in series. Then look at the capacity of the battery block, for example 4400mAh, then prove that the two groups mentioned above, the series battery,

because the small battery capacity is 2000-2200mAh, or even more, and together the two groups can be reached 4400mAh. According

Laptop batteries by the case, Dell original inspiron 1525 Batterycircuit boards and batteries, belonging to lithium-ion battery. Ordinary people talking aboutAcer travelmate 2420 series Battery batteries means the number of batteries within the battery, mAh refers to the capacity of notebook batteries. Mainly by the protection circuit board (or secondary protection),

and the capacity indicator circuit composed of two parts, on the laptop battery charge and discharge and safety management. Laptop battery standby time determined mainly by the mAh value. In general, the more the batteries, mAh greater the longer standby time. Notebook battery life mainly to measure the charge and discharge times, the quality of the products qualified for the 500-600 times normal. Therefore, the effective use of laptop battery within a period of 2 years,Hp dv6000 Battery the battery will expire
