Five questions of rechargeable battery knowledge

Small, lightweight and portable products like digital cameras, MP3/CD players, portable speakers and so on are becoming more mainstream of the digital family, while the batteries are also playing a role increasingly important. The higher cost can be repeatedly used in rechargeable batteries to become the first choice for many people, but the market under various slogans of the rechargeable Laptop battery is great, there is great capacity announced, there announced a fast charge, coupled with the use of different kinds of doubts, so many people scratching their heads advantages and disadvantages of rechargeable batteries. This issue, we have summarized the top five on the rechargeable battery in doubt, we want to help you buy rechargeable batteries.

Question 1: for life or high capacity?

Many people believe that the capacity of rechargeable batteries, the more the better, you can buy so often ignoring their real needs, Aspects of Intellectual Property “big” purchase. In fact, the capacity of the life cycle of the battery pack is much less than the low battery capacity. 1600 milliamps, for example when the rechargeable battery, a standard charger can be recycled under the conditions of charging more than twice 800-1000; 2400 milliamps, but the standard charge when the battery only in the cycle of less than 300 time! This is why rechargeable batteries a few times, more and more without using a why. But like the professional digital camera, flash and other high-power digital devices, a high capacity rechargeable Dell Latitude D620 battery always has its advantages.

Question 2: Charging the penalty, life shorter?

Market a lot of requests “two hours of fast charge”, “1 hour quick-charge” or even “30 minutes of quick charge” of fresh produce have been favored by many consumers, but all. In fact, the technology of fast charging, at the expense of cycle life of rechargeable batteries, the cost, such as 1850 milliamps when the rechargeable battery, the standard state of charge May be 800-1000 times more cycles load, but if we adopt the fast charge mode, then the number of cycles of loading cycles may only be 200 times less. In addition, the battery fast charge will affect the use of once, because often , are filled to capacity fast charge battery about 70% -80%, and 2000 mAh, with 2 hours fast charge mode to require the case, believes that only the load capacity of 1500 mAh. Therefore, under the condition of existing technologies fish and bear paws can not eat. To quickly save time, or a longer service life depends on their needs.

Question 3: The battery can be charged with the other nine?

Many people may know that such “common sense: If the battery is not fully the conduct charged, the hp 367759-001 battery is then that the initial state of the memory capacity, load and then use only the new load in the power of electricity as well. This increase is explained by the effect of memory characteristics of nickel-cadmium rechargeable batteries, much needed to fully discharge before recharging. But it is now more popular market is the nickel-metal hydride rechargeable batteries without memory effect, at any time to charge a supplement.

Question 4: a new battery for the first time in charge of “overload”?

There is also a famous “common sense” is a new battery charge for the first time to go through the overpayment, “the process to fill the 10 hours before the battery to reach full saturation. This is the fault of nickel-cadmium batteries, “bad”. Nickel-cadmium batteries in the past in order to reach saturation more perfect, the need to pass by “overloading” process usually takes 12-16 hours. Now, many brands like Nanfu introduced rechargeable batteries fully charged after 6-8 hours, support smart charger with voltage, time and device temperature protection, Auto-off charge until then to charge the sony VGP-BPS2A battery for more than 12 hours following the approach has no practical importance.

Question 5: The different brands of chargers can not be mixed?

Since each feeder has a fixed size of the output current, the current production capacity of the battery by its number of correspondents, not suitable for other battery capacity, so if they are mixed, then the loading process the battery is subject to burnout or may never fully charged and so on. In addition, if the charger is not an intelligent security protection against overload and other characteristics, it is very likely due to the persistence of charge the battery while the explosion “full” battery.

The purchase and proposed

So if you normally be able to learn more about some of the characteristics of rechargeable batteries and the purchase and use of knowledge, we can make better use of rechargeable batteries, protection of digital cameras, MP3 and other digital devices play a key role. On the other hand, choose the well-known brands of rechargeable products, is also a good choice. While the price may be more expensive than regular brands, but in terms of quality or reliability standpoint, well-known brands will be more comfortable with people

14 kinds of mobile phone battery charging tips

Users want to extend the effective use of battery time, in addition to the quality of the shipper must have guarantees are essential for the proper loading techniques, because the poor quality of the charger or charging the wrong methods will affect the battery life and the life cycle, following the technical support:

1. The battery factory, manufacturers have made active treatment, and conduct pre-charge the batteries have more than electricity, one of my friends said that the battery charge in accordance with the period of ‘adjustment, standby is still a serious shortage, if the battery is indeed the battery brand, then this case adjustment period should be extended another 3 to 5 times fully charge and discharge.

2. If you buy a new cell phone battery is a lithium-ion battery, then the first 3 to 5 charge time commonly called an adjustment period, more than 14 hours should be sufficient to ensure full activation of the lithium - ion activity. Lithium-ion battery without memory effect, but a strong inert, should be given to fully activated to ensure that used to achieve best performance.

3. Some automated intelligent rapid charger when the lights change direction, but it was only 90% full. Charger will automatically change with the slow loading of the battery is full. Is best used when the battery is full, otherwise it will shorten the duration of use.

4. Before charging, lithium batteries do not need special discharge, discharge improper apple A1079 battery will be damaged. Charging as much as possible to slow charge to reduce the fast charge mode, time should not exceed 24 hours. After three to five times the battery fully charged and discharged its internal chemicals will be all the “activation” for best results.

5. Please use the original or the reputation of a good brand of chargers, batteries use lithium battery charger lithium dedicated, and follow the instructions, otherwise it could damage the battery or even dangerous.

6. There are many users, often in charge when the phone open, in fact, it will hurt the mobile phone life very easily, because only in the charging process, the cell phone circuits will be the fever at that time ’s there are external phone, you may produce transient current feedback, to damage the internal parts of the phone.

7. The battery life determined by the number of repeated charge and discharge, he should try to avoid that the Dell 6Y270 battery during charging, it will shorten the lifespan of the battery. Phone battery off for more than 7 days should be the first mobile phone is fully discharged, adequate electricity and then use.

8. Mobile phone battery self-discharge exist, not when the nickel-hydride batteries, metal a day to about 1% of the remaining capacity of the discharge, lithium batteries a day 0, 2% ~ 0.3% of landfill. Charging the battery, try to use a dedicated outlet, do not leave electrical appliances such as charger and TV.

9. Although the network coverage of mobile telephony in the region, but the phone off when charging is more acceptable and appeal. At this point, you can use the phone is not connected to the transfer of functions have been transferred to the side of the landline phone to avoid the loss of calls, this method is not for network coverage mobile phone in the area of weak signal, or is temporarily unable to connect when you apply.

10. Do not expose the hp 367759-001 battery to warm or cold as a dog day, and turning the phone on the car to withstand exposure to blazing sun, or get air-conditioned room, the air conditioning blowing right places. When charging the battery a little heat is normal, but can not be Jinshou high temperature “suffering.” To avoid such situations, it is preferable to perform at room temperature during charging, and does not cover anything on the phone.

11. Nickel-cadmium (N ICD) must ensure that the battery until the battery completely without power, then in charge must ensure that the battery is fully charged.

12. If the mobile phone battery to attach too long without employment, it is best to call the maintenance department to apply to batteries for treating live, you can have a device constant DC voltage by adjusting the voltage of 5 ~ 6V, Current 500 ~ 600mA reverse battery connector. Note that the liberalization of touch, most can be repeated three times, after such treatment, re-use original charger “adjustment” charge.

13. The higher the load when it is not good, not to protect the IBM ThinkPad T42 battery from full charge circuit should be stopped immediately, otherwise the battery overheating due to heat or impact performance.

14. Dedicated lithium-ion battery charger must be selected, or they may not reach saturation, the impact on its performance. After loading, the shipper must avoid placing more than 12 hours or more in the long term without the battery and cell phone must be separated.

Talking about battery hazards

These last two years, the environmental impact of waste batteries becomes hot topic in one of the national media. Some have reported that the battery of environmental pollution is very serious, a battery can contaminate hundreds of thousands of cubic meters of water. Some even say that with the disposal of waste batteries can cause Minamata disease, such as Japan, as the danger of these reports have generated a great response, there is a lot of love for people and organizations to take measures to protect the environment or to participate in Laptop battery recycling business waste.

However, the State Administration of Environmental Protection say that does not focus on recycling of used batteries, used batteries damage the environment before the reports of the lack of scientific basis, to some extent led to deceive the masses. So, how to treat the batteries before science? This article aims to inform to the issue, to help you understand the more scientific treatment of waste batteries, better protection of our environment.

Rubbish inside the battery ultimately what contaminants

Environmental Science and Engineering, Tsinghua University, tutor of doctoral student Yong-Feng Nie, Professor, leading research group devoted to the risks and the elimination of waste batteries, research has been done. He said that in recent years, the batteries on the reports of harm to the environment, there are many, but unfortunately, these reports did not explain to readers or viewers to support his findings of the content research, there is no incentive for readers to submit their analysis process, there are no lists the actual pollution caused by the case of the dry Dell FK890 battery, only pollution “serious” conclusion.

Waste batteries containing hazardous substances, these substances through such a mechanism of release into the environment, would be the extent of damage to the environment, availability of internal and external batteries causing serious pollution cases, developed countries is how to solve this problem? with doubt, the research group conducted a survey on the depth and concluded with a number of far cry from news reports, these reports there is no practical and radical of the Office.

Professor Nie said the batteries can be divided into a (normal dry cells) of secondary batteries (rechargeable, mainly used in mobile phones, computers), lead acid batteries (mostly used in cars) three categories. Use the more the masses are more concerned by the reports of most ordinary batteries. Described below refer to a conventional hp 367759-001 battery and dry.

The batteries are made of iron, zinc, manganese, etc., plus traces of mercury, mercury are toxic. It was reported that in general, batteries containing mercury, cadmium, lead, arsenic and other substances, it is not true. In fact, the masses of ordinary dry batteries for daily use in the production process without added cadmium, lead, arsenic and other substances.

The piles of waste, mercury does not pose a threat to the environment

Low temperature volatilization of mercury is a highly toxic heavy metal. Many parts of the world also contain trace amounts of mercury in the mercury mining, refining, processing of mercury containing products, such as the measures are not confined sufficiently complete, the release of mercury into the atmosphere (steam) on the health of the operator a great influence.

May batteries contain mercury, but because it is additive, its concentration rarely. Even high-mercury batteries, mercury batteries are generally less than one thousandth of the mass. The Chinese sony VGP-BPS5 battery with the annual amount of mercury, usually in line with mercury, polyvinyl chloride, or alchemical mercury, lead and zinc mining and dressing or high emissions of mercury from companies wastewater in the year a considerable quantity of mercury. Since the battery consumption of the vast region the mercury batteries in the system of waste disposal, after the environmental impact of chemical emissions than its predecessor, the impact of mercury-containing wastewater is much smaller addition, the battery used in stainless steel or carbon steel because of the external foreskin, prevent leaks of mercury. Therefore discarded used batteries garbage scattered in life, the damage is minimal objectively impossible, as the Minamata disease caused the damage. Japan, Minamata disease is a chemical company for a few decades a large number of flows of rivers of mercury-containing wastewater, the gradual accumulation of mercury in the river downstream of the system caused.

Containing mercury, batteries are replaced by mercury-free BTP-43D1 battery

Of course, mercury, batteries, waste, after all, has a negative impact on the environment (even slightly). Thus, at the end of 1997, Economic and Trade Commission, China Light Industry Association and nine other ministries jointly issued a “restriction on the provisions of mercury batteries,” learn from the experience of developed countries require manufacturers of internal battery to gradually reduce the mercury content in batteries in 2002, domestic sales of batteries to achieve low-mercury, the mercury reached in 2006.

From practical point of view of progress, the domestic industry manufacturing the battery according to the basic “rule” requires the progressive reduction of mercury content in batteries. According to data from the China Battery Industry Association, the battery production in China to 180 dollars, exports about 10 billion euros, the annual domestic consumption of about 8 billion euros, standards Base hit a low of mercury (mercury content less than 0.025% by weight of batteries). Of these, approximately 2 billion of mercury-free standards (weight of mercury batteries less than 0.001%).
