How to rechargeable batteries
Rechargeable Battery

A limited number of charge rechargeable batteries with charger. The market generally sell on the 5th, the 7th, but there on the 1st. Benefits of rechargeable batteries is economic, environmental, power enough for high-power, long-term use of electrical appliances (such as Walkman, electric toys, etc.). Charging the battery voltage is lower than the same type of disposable batteries, AA batteries (the 5th charging) is 1.2 volts, 9V rechargeable battery is actually 8.4 volts. Charging times can now generally around 1000. At present, only five categories: nickel-cadmium, nickel metal hydride, lithium ion, lead accumulator, lithium iron.
Steps / methods

Timing control
When using 1.25C charge rate, the battery 1h be sufficient; When using 2.5C charge rate, 30min be sufficient. Therefore, according to the capacity of the battery and the charging current, it is easy to determine the time required for charging. This control method is the most simple, but due to the initial state of charge of the battery is not exactly the same, and some lack of battery charge, and some battery overcharge, therefore, only the charge rate is less than 0.3C, it allows the use of this method.
Voltage Control
In the voltage control method, the most likely to be detected is the highest voltage of the battery. Voltage control law is used:
The maximum voltage from the charging characteristic curve can be seen, when the battery voltage reaches the maximum value, i.e. the battery is fully charged. During charging, when the battery voltage reaches a predetermined value, should immediately stop fast charging. The disadvantage of this control method is: the highest voltage battery is fully charged with the ambient temperature, the charging rate change, and the maximum charge voltage of each cell there are differences in the battery pack, so this method can not be very accurately determine the battery has enough charge.
Negative delta voltage increment due to the negative battery voltage and the voltage of the battery pack is absolutely nothing to do, but also affected by environmental factors such as temperature and charge rate, so you can more accurately determine the battery is fully charged. The disadvantage of this control method is: the battery voltage negative increment, the battery has been charged, so the higher temperature of the battery. Also after the nickel-metal hydride battery is fully charged, the battery voltage to go through a long time before a negative increment, the overcharge is more serious. Therefore, this control method is mainly used in nickel-cadmium batteries.
Voltage zero incremental NiMH battery charger in order to avoid negative voltage increments wait for too long and damage the battery, usually 0V Control Act. The disadvantage of this approach is: fully charged before the battery voltage may vary within a certain period of time is small, resulting in a premature stop rapid charging. For this reason, most nickel-metal hydride batteries are used highly sensitive detection of fast charger when the battery voltage drops slightly, immediately stop fast charging.
Temperature Control
To avoid damage to the battery, the battery temperature is too low can not start fast charging, the battery temperature rises to a predetermined value, you must immediately stop fast charging. Temperature control methods are commonly used:
The maximum temperature during charging, typically when the battery temperature reaches 45 , should immediately stop fast charging. The battery temperature and the battery may be assembled together by a thermistor to detect. The disadvantage of this method is the long response time of the thermistor, the temperature detection with a certain lag, while the maximum operating temperature of the battery and the ambient temperature. When the ambient temperature is too low, after fully charged, the battery temperature does not reach 45 .
In order to eliminate the environmental impact of temperature, temperature control method can be used. When the battery's temperature reaches a predetermined value, immediately stop fast charging. In order to achieve temperature control, the thermistor must be two, respectively, to detect the battery temperature and the ambient temperature.
Temperature change rate of nickel metal hydride and nickel-cadmium battery is fully charged, the battery temperature is rising rapidly, and the rate of rise T / t basically the same, when the battery temperature rises 1 per minute, shall immediately terminate fast charging, this charging control method, in recent years, come to be widely used. It should be noted, due to the temperature dependence of the resistance of the thermistor is not linear, and therefore, in order to improve the detection accuracy of the thermistor should try to reduce the impact of nonlinearity.
The lowest temperature when the battery temperature is below 10 , the use of high-current fast charging, it will affect battery life. In this case, the charger should automatically transferred to trickle charge until the battery temperature rises to 10 , and then transferred to fast charging.
Integrated control
These various control methods have advantages and disadvantages. In order to ensure that in any case, be able to accurately control the battery charging * state, the current fast charger usually include timing control, voltage control and temperature control integrated control method.Laptop Akku

How to identify the cell phone battery quality is good or bad
1 Comparison of the size of the battery capacity. General 500mAh Ni-Cd battery or 600mAh,
Nickel-hydrogen batteries, but also 800-900mAh; lithium-ion cell phone battery capacity is generally between 1300-1400mAh, so time after fully charged lithium-ion battery is about 1.5 times using nickel-hydrogen batteries, nickel cadmium batteries 3.0 times. If you find that you have purchased a block of lithium-ion cell phone batteries no longer working hours and provisions on brochures or, it may be fake.
2 see the plastic surface and plastic material. Genuine battery wear surface evenly, using PC material, no embrittlement phenomenon; counterfeit batteries no wear face or too rough, using a renewable material, easy to rattle.
3 All genuine mobile phone batteries, the appearance should be neat, no extra burr, the outer surface has some roughness and comfortable feel; inner surface is smooth feel, the light can be seen fine vertical scratches. Cell phone battery electrode with the same width, the corresponding position marked under the battery electrodes [+], [-] mark, battery charging electrode of the same material as the insulating material and the shell, but not one.
4 For the original battery, its battery surface color texture clear, uniform, clean, no scratches and damage; battery symbol should be printed on the battery model, type, rated capacity, standard voltage, positive and negative signs, factory name. Smooth feel to be on the phone non-blocking, elastic fit, and the hand with a good, reliable lock; hardware pieces no scratches and black hair green phenomenon. If the phone battery with the above phenomenon we buy does not comply, can initially concluded that it is fake.
5 Currently, many mobile phone manufacturers also from their own perspective, through efforts to improve the level of technology to improve fraud difficulty phones and accessories to further curb the spread of the phenomenon of parallel fake. General formal requirements of mobile phone products and accessories must be consistent in appearance. So when we bought the phone if the battery installed, you should look carefully control the color of the body and the battery pan, if the color and brightness consistency, is the original battery. Otherwise, the battery itself is dull dull, it may be fake batteries.
6 observed anomalies charge. In general, there should be genuine mobile phone battery internal overcurrent protection device, resulting in excessive current in the case of an external short circuit, automatically cut off the circuit, so as not to burn or damage the phone; lithium-ion battery also has over the line, when using non-standard electrical , AC electric current is too large will automatically cut off the power supply, resulting in the charge does not enter, in normal circumstances, the battery can be automatically restored to the conduction state. If we in charge of the process, found that the battery severe fever or smoke, or even an explosion, indicating that the battery is certainly false.
7, a closer look at security signs. NOKIA words such as hidden under stickers printed diagonally, is one of the tricks. Flawless clarity is the original product; dim pale counterfeit products. If you take a closer look, it may find the manufacturer's name. For example, Motorola batteries, it's anti-counterfeit trademarks are diamond-shaped, and from whatever point of view, can flash a three-dimensional effect, while Motorola, Original and printing and clear, then, would constitute genuine. On the contrary, once the color of dull, lack of three-dimensional sense of vague words, there may be a fake.
8 measuring the charging voltage of the battery block. If the counterfeit lithium-ion cell phone battery block with nickel-cadmium, nickel hydrogen batteries block, it must be composed of five single cells, a single battery charge voltage is generally not more than 1.55V, the total voltage of the battery block does not exceed 7.75V. When charging the total voltage is below 8.0V battery block is likely to be nickel-cadmium, nickel hydrogen batteries. laptop batteries

Buy cell phone batteries look "3C" sign

Song diligent said battery manufacturing process is very precise, generally small factory custom-made cell phone batteries, protective shell internal pressure relief device is not set, the battery in the long-term use or charging process, prone to hot phenomenon, serious and even when the explosion occurred . In addition, custom battery more for refurbished products, rechargeable batteries even after their useful life is very short, so consumers buy such products outweigh the benefits. compaq laptop batterie

Business sector to remind consumers to buy mobile phone batteries should look for the "3C" certification mark, but also check the battery's rated voltage, rated capacity and other information. Meanwhile, the consumer is best to a regular cell phone store to purchase brand batteries, and require businesses to issue invoices for future rights used. If you find businesses for sale "three noes" mobile phone batteries, consumers can report to the relevant departments.dell laptop batterie Industry profits spawned custom battery business

Song engaged in mobile phone repair years of diligence that the phone battery OEM business seemingly low prices, in fact, there are huge profits to be made.

"Custom-made cell phone batteries are mostly old batteries refurbished. Piece of old phone battery recycling price of about $ 3, after a few hands, then the price can turn into the market ten times." Song diligent says that after recovery, the old buyers batteries for about 10 yuan per block wholesale prices to the battery refurbished processing point, the latter then the original battery casing removed, remove the batteries, which can be used to recharge batteries, re-dusting, polishing, and put the new shell, so that a "new battery" was born, its priced at 40-60 yuan. acer laptop batterie

Song diligence that vendors claiming to produce their own cell phones, in fact, mostly from underground battery factory in the south. Custom-made cell phone battery greatest demand is parallel phone vendors, original battery before many parallel phone sales, comes out will be vendors, resale sold the retail market and earn more profits. After that, the business of custom battery into the box and then posing as the original battery.

Mobile phone battery can be tailored? It should also be carefully chosen

Today, mobile phone battery OEM business in the streets quietly. But many consumers reflected some businesses custom-made cell phone battery power consumption quickly, and the use of prone hot phenomenon. Insiders said that the streets selling customized mobile phone batteries, product quality without security, there are security risks.

Custom battery more as a "three noes" products

"I thought picking up a cheap, did not expect to buy the battery quality is so poor." Public ػ said in mid-June, he spent weeks in the vicinity of King City Plaza 40 yuan a piece of custom-made cell phone battery, available two weeks after the discovery, every dial phone battery began hot, due to worry about the battery will burn the phone, had abandoned.

Yesterday, in the vicinity of Zhou King City Square, there are many banner of "custom-made cell phone battery" signs of traders. A vendor introduced an ordinary mobile phone battery to be custom-made 40 yuan, if the custom 1800 mA or larger capacity battery, you need 60 yuan.

"As long as a day to do a battery raw materials are all imported materials, poor quality than the original battery." Traders from the bag and pulled out a cell phone battery that this battery is someone else yesterday customized HTC (G14) mobile phone batteries, "This mobile phone original battery less have more than 100 yuan of money one, but then as long as 50 yuan custom. "

Reporters found that a lot of custom-made cell phone batteries, neither marked above the rated voltage, rated capacity, nor the manufacturer, date of manufacture, etc., belong to the "three noes" products.
