the characteristics of lead-acid batteries and

• the characteristics of lead-acid batteries (for FM, GFM, SW series)
1. sealing: prevent the leak acid by battery for Sony np-fm50 slot cover, pole double seal design , a reliable safety valve to prevent the external air and dust into the battery inside;
2. maintenance-free: water regeneration ability, and sealing of high reaction efficiency, so the whole process of using the battery without overtime pay or adding acid maintenance;
3. safe and reliable: No acid spill, reliable self-closing safety valve, explosion-proof equipment, equipment that enables the use of race to the Sony np-fm55h battery in the whole process more secure and reliable;
4. long-life design: a computer-designed fine corrosion-resistant lead-calcium-lead alloy grid, ABS corrosion-resistant materials, use and high reaction efficiency seal ensures long battery life;
5. high performance:
1. body weigh of lead-acid Sony np-fp50 batteriest is higher than the energy , resistance is small, output power is high;
2. charge and discharge high-performance, self-discharge control of each month, less than 2% (20 ℃);
3. recovery performance is good, in deep Discharge or charger failure, short-circuit to place 30 days after the charging method so that it can still be used to restore a balanced capacity;
4. As the single battery internal resistance, capacity, float voltage uniformity is good, so the use of battery for Sony np-fp90 in float a state of equilibrium without charge.
6. temperature adaptability: the akku can be -30 ℃ ~ 50 ℃ under the safe, secure use;
7. easy to use and transport safety: Man charged the factory, no free electrolyte, the battery can be placed horizontally, and can be non-hazardous materials for water, land transport;
8. economical: Burke battery for Sony np-fr1 high performance, long life, low maintenance costs to ensure that users get the most cost-effective products.
• The battery discharge
1. the discharge termination voltage

The Sony np-fs11 battery should not be discharged below a predetermined termination voltage will cause excessive discharge, which would result in repeated over-discharge capacity of difficult to restore, in order to achieve the best efficiency and longest life, discharge should be between 0.05-3C;

2. the discharge capacity:
1. the discharge capacity and discharge current relationships: the series of batteries for Sony np-fs21 has the different capacity at different discharge rates , the greater the discharge rate, the battery of the the smaller capacity can be released.
2. Temperature effect: the Sony np-ft1 battery capacity is subject to the influence of temperature, low temperature (below - 15 ℃ / 5 ℉) would reduce the effective capacity, high temperature (higher than 50 ℃ / 122 ℉) would lead to thermal runaway and damage to the battery.

lithium-ion battery

Mobile phone xps m1530 battery is divided into three major categories on its manufacturing material: nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion battery. One nickel-cadmium batteries are the first generation of mobile phone battery, it is a low capacity, there is memory effect, requires frequent discharge to maintain capacity, and creating materials, there is environmental pollution, the current cell has been basically eliminated. Second-generation high-capacity Ni-MH Fujifilm NP-95 battery, no memory effect, manufacturing, materials, little environmental pollution, people used to call it environmentally friendly batteries. The current development trend of mobile phone battery is a lithium-ion battery, its advantages are:

1. no memory effect, no discharge, the use of a long time.
2. a high voltage. Usually single lithium-ion battery voltage of 3.6V, Ni-MH, Ni-Cd xps m1730 battery voltage of 1.2V, a difference of 3 times.
3. small size, light weight, high specific energy. Lithium-ion battery energy density of up to nickel-cadmium batteries two times. Ni-MH battery with the same volume compared to the volume can be reduced by 30%, weight can be reduced by 50%.
4. long life. High-quality lithium-ion
xps m1330 battery life of up to 1,200 times or more, much higher than other types of batteries.
5. safe and fast charging. Lithium-ion batteries due to use of special technical processing, thereby allowing fast enough within 2 hours of electricity, but also greatly improved safety performance.
6. allows a wide operating temperature range. Lithium-ion battery for Nikon EN-EL8 can work between -20 ℃ -60 ℃. High-temperature discharge performance is superior to other types of batteries.

So how to identify genuine and fake batteries? In the non-professional conditions, can use the following methods: equal-capacity battery, lithium battery for Nikon EN-EL1 than the nickel-metal hydride and nickel cadmium batteries feel lighter; dedicated lithium battery charger with the battery charge, if the process of charging the battery heat, then the is a nickel-metal hydride, nickel cadmium batteries, if no major changes in temperature, it is lithium battery; to make the battery positive and negative "instantaneous" short-circuit before use, such as theNikon EN-EL9 battery, "no power" is a lithium battery, if still "have electricity" is a nickel-metal hydride, nickel cadmium batteries.

The use of lithium batteries should be noted for a period of time ,after the battery is placed it can go into hibernation, lower than normal capacity at this time, use of time has also come to shorten. After 3-5 times rechargeable Olympus li-40b battery can be activated to restore normal capacity.

When the battery is inadvertently short-circuit when the internal lithium battery protection circuit will cut off the power supply circuit in order to ensure the safety of users will be out to re-charge the akku can be restored.

To buy lithium batteries, should choose after-sales service, international, national identity, brand batteries, take the Nikon EN-EL11 battery for example , such batteries are made of high quality raw materials, with comprehensive protection circuits, shell beautiful, wearable, with security chip, and with mobile phones with the good can be achieved Good communication results.

Battery recycling is a problem

January 21, Chung-tai 2008EV hit the domestic market first mass-produced electric car flags. Also started to manufacture the Casio np-100 battery, and has been walking in the forefront of BYD electric vehicle research and development in china as well. There are indications that new energy vehicles The technical line has been quietly shifting to electric cars, in 2010, new energy vehicles to enter the full "electric shock" era.

• Environmental protection need a prerequisite

Energy use up clean, but its manufacturing process is also clean it? At present, China's coal-based energy generation, followed by hydropower, nuclear power a very small proportion. Coal-fired power plants in the production of electricity, the emissions of carbon dioxide from Nikon en-el3 battery to be much less than the fuel cars. However, the number of electric vehicles soared, the carbon dioxide emissions is still not a small number .

• Battery recycling is a difficult issue

As we all know, the xps m1710 battery contains heavy metals, acid, alkali and other substances. In the usual process of using these substances have been encapsulated in the shell, it will not harm the environment and the human body. But when the battery was abandoned, due to the long-term mechanical or corrosion effects, making batteries and other heavy metals and acid-base leak out, it may cause serious environmental pollution problems. In addition, some after the acquisition of plant acquisition of scrap akku , only a simple removal, whichever is useful to some, but will the rest discarded into the environment. The same may lead to serious environmental pollution. If you can establish a unified recycling system for the regeneration technology is not perfect, or energy-consuming, expensive too large, it is recommended a centralized approach to deep landfill. But the best way is still using reasonable recycling Jvc bn-vf808 battery technologies to avoid waste of resources.
