Batteries INFO

Battery types and characteristics of

Nickel-cadmium battery (Ni-Cd): It is used in notebook batteries senior figures, Hp laptop battery,but because it has serious memory effect as well as the anode material used in nickel (Ni) on the environment will be toxic and cause pollution, it is notebook soon be abandoned, and replaced by the better nickel-hydrogen batteries.

Nickel-metal hydride battery (Ni-MH): It is the structure of nickel-cadmium batteries are basically the same principle, F4812A, 319411-001, Presario 2100(compaq 2100), Presario 2500(compaq 2500 battery), Presario NX9010,only the cathode into better performance, more environmentally-friendly non-toxic Nickel - Metal Hydride Materials. Although it was only a small change, but it has brought performance greatly enhanced. It also has a way to make nickel-cadmium batteries to catch up with the advantages of memory effect is not obvious, thus we do not have to hate for the memory effect of the troubles and thus more convenient to use. Although Ni-MH battery performance is very good, but with technological advances it was the quality of lighter, higher energy density lithium batteries replaced, has become a laptop battery in the history of flower of yesterday.

Lithium battery : a lot of people think that lithium batteries means that we now commonly used in lithium polymer batteries, F4812A,lithium batteries in fact, lithium-ion batteries including the (Li-MO2) and lithium polymer batteries (Li-ion) two. Since Li-MO2 battery to enter the market in 1989 when the bombing happened on fire and collapse, thus it from the people's attention quickly disappeared, replaced by safer lithium polymer batteries. Its light weight, in the same capacity under its weight of only Ni-MH batteries 1 / 2 around, so it quickly became the movement's new darling of portable devices has been used by the majority of laptop, notebook batteries are now the backbone.

Fuel Cell (Fuel Cell): fuel cells are the future of notebook battery star, it has a lot of types, including proton exchange membrane fuel cell (PEM), alkaline fuel cell (AFC) and solid oxide fuel cell (SOFC), etc. However, because of the fuel cell start-up time and operating temperature and other reasons in fact suitable for laptop use only the fuel cell proton exchange membrane fuel cell (PEM). PEM fuel cells are methanol fuel used and so on,F4812A, 319411-001, Presario 2100(compaq 2100), Presario 2500(compaq 2500 battery), Presario NX9010, by the positive and negative electrode composed of the principle of its power generation is the result of methanol to hydrogen re-enter the anode and oxygen enter the cathode, through the catalyst, hydrogen atoms into protons and electronics, by different path into the cathode,319411-001, electronic electricity generated through internal cycle, protons through the electrolyte to reach cathode, combine with oxygen and electronic hot water and after. The experts agreed that restricting commercial application of fuel cells The biggest factor is the fuel cell to use metal platinum (Pt) or platinum catalyst to do so that production costs have been high, the current fuel cell production costs in the 500 ~ 1000 U.S. dollars / kW. Studies have shown that only when the fuel cell production costs fell to 50 U.S. dollars / kilowatt level can be truly accepted by consumers. Fuel cells are the main reason for the high cost of production has yet to take shape, once mass production stage, the price of fuel cells battery will certainly be greatly reduced.

Electric car battery maintenance

At present, non-polluting electric vehicles because of their advantages such as light and favored by consumers, and mileage are the consumer to measure the length of electric vehicles, one of the main criteria for good or bad. As we all know, electric vehicle batteries are played a decisive role, F4812A, 319411-001, Presario 2100(compaq 2100), Presario 2500(compaq 2500 battery), Presario NX9010,then the electric car battery maintenance should pay attention to what problem? The following advice is for reference only.

First, when stored electricity deficit

Deficit refers to the status of electric batteries did not recharge after use. Electricity in the loss of state under sulfate, Presario 2100(compaq 2100),lead sulfate crystals attached to a very board, plug the electric ion channels, resulting in charge did not fall. Electricity losses the longer the idle state, the battery battery, the more serious damage.

Second, regular inspections

In the use of process, if the continued line of electric vehicles in a short period of time a sudden drop in mileage more than ten kilometers, it is likely that the battery pack at least one battery has appeared off grid, plate to soften, falling plate active material, such as short-circuit phenomenon . At this point, should be timely and professional bodies to check the battery repair, restoration and distribution group. This can extend the battery life relative to maximize cost savings.

Three, to avoid large current discharge

Electric cars at the starting line, manned, uphill,F4812A, 319411-001, Presario 2100(compaq 2100), Presario 2500(compaq 2500 battery), Presario NX9010, please use pedal power to help avoid a momentary high-current discharge.Presario 2500(compaq 2500 battery), Large current discharge have easily lead to the crystallization of lead sulfate, to the detriment of the physical properties of the battery plate.

Fourth, correctly grasp the charging time

In the use of process, should be based on the charging time to grasp the actual situation, the general batteries are recharged at night, the average time in about eight hours. If the shallow discharge, the battery will soon be filled and continue to charge-off charge will appear, and that leads to cell loss, fever, lower battery life. Therefore, the battery to discharge a depth of 60% -70% of an electric charge the best, according to their own actual conditions to carry out the necessary charge to avoid the harm of sexual charge.

Fifth, to prevent exposure

Electric vehicles is prohibited under the sun exposure.Presario NX9010, Environment temperature is too high will increase the internal pressure of battery automatic pressure limiting valve are forced open, a direct consequence of the loss is to increase cell volume, while the battery is bound to lead to excessive water loss decreased cell activity, accelerating the plate to soften, charging shell body fever, from drums,F4812A, 319411-001, Presario 2100(compaq 2100), Presario 2500(compaq 2500 battery), Presario NX9010, deformation such as a fatal injury.

Sixth, avoid charging out hot plug

Charger output plug loose contact surface oxidation would result in such phenomena as variable charging plug hot, heating time is too long will lead to short-circuit recharging plugs, direct damage to the charger, lead to unnecessary losses. Therefore, the discovery of the above situation, should be cleared or replacement connector oxides.
