Nickel-cadmium Batteries Can Be Reused In More Than 500 Charge And Discharge, Very Economy

First, the nickel-cadmium batteries (Nickel-Cadmiun Batteries) features

1. Nickel-cadmium batteries can be reused in more than 500 charge and discharge, very economy;

2. Resistance is small, for large current discharge, discharge voltage when it changes little, as the DC power supply is an excellent quality of the battery;

3. Because the use of fully enclosed, so there is no electrolyte leakage phenomenon, but also completely without added electrolyte;

4. In contrast with other types of batteries, nickel cadmium batteries can withstand overcharge, or let go of power, simple operation;

5. Nor will place a long time under the performance deterioration, when fully charged is able to resume after the original property;

6. Can be used in a wide temperature range;

7. Because it made use of metal containers which have mechanical robustness;

8. Nickel-cadmium batteries in under very strict quality control to be manufactured, with very good depends on the quality of sex. Dell Inspiron 1300 battery dell D820 battery Dell gd761 battery Dell kd476 battery

With all the hands of the Ni-MH battery is constantly increasing number of scientific leap into the use and maintenance are increasingly concerned about the line of sight to everyone. As we all know, brand Ni-MH battery life can be charged at the official claim that 500-1000 times, in fact, this is a good value, often less than this life. But as long as a reasonable use of the charger, a more in-depth understanding of the nickel-metal hydride batteries, we can still do her longevity.

1. In general, the new nickel-metal hydride batteries contain only small amounts of electricity, we purchase and then charging after the first use. But the relatively short time if the battery factory, power is adequate, it is recommended first use and then recharge.

2. Buy a new nickel-metal hydride batteries are generally 3-4 times the charge to go through and use to play to the best performance, charge a lot of friends for the first time encountered a small Dell pc764 battery Dell Inspiron 640m Battery Dell Latitude D800 battery Dell Inspiron 600m batteryproblem, for example, taken after the first charge did not imagine the number of PP so much? In the 3-4 times after charging and use have been solved.

First, the lithium battery introduced

Lithium into two categories: non-rechargeable and rechargeable. Non-rechargeable batteries as disposable batteries, it can only be a one-time chemical energy into electrical energy, electrical energy can not be restored back to chemical energy, such as lithium manganese dioxide batteries. Rechargeable batteries as secondary, which is commonly known as lithium-ion battery (LI-ion). Lithium-ion battery cathode of lithium-containing transition metal oxides, carbon anode is a material such as graphite, etc., containing lithium salt electrolyte is an organic solution. Both positive and negative cells or in the battery separator, the lithium ions in the form are to exist. Batteries at work, the lithium ion in the positive and negative electrodes and electrolyte ACER LC.BTP00.006 Battery APPLE A1175 battery APPLE A1189 battery ASUS A32-F5 Batterymembrane in the directional movement. When the battery is charging, the cathode of lithium ion to the electrolyte release, this process is de-embedded; negative ion from the electrolyte in the inhalation, the process is embedded. The battery discharge process and the situation is reversed, this time charging and discharging the lithium ion intercalation and deintercalation from the process as like a rocking chair swaying, it was the image of said lithium-ion battery as a rocking chair batteries.

Lithium-ion batteries and nickel-metal hydride battery, has many advantages. Lithium-ion

battery memory effect does not exist; the same capacity, the volume is very small; use voltage of 3.6 V, is the nickel-cadmium batteries, nickel metal hydride batteries 3 times; can be used in wide temperature range (-20 ~ 60 ) , and Ni-MH battery (0 ~ 50 ). While lithium-ion battery self-discharge rate is relatively low. Self-discharge rate refers to the period of time, do not use the battery in case of loss of power automatically percentage of total capacity. Usually at room temperature, Ni-MH battery from 25% to 35% per month, while the lithium-ion battery is only 5% to 8% per month. But lithium-ion batteries are also some people are not satisfied. Such as: lithium-ion batteries have life, usually two years, and do not use the state in the storage period of time, some of its capacity will be permanently lost. Lithium-ion battery anode material from the factory has already begun its failure in history, different temperature and battery fully charged state, its impact is different from Table 1 data (capacitance accounts for the remaining percentage of the original capacity) of column.
