Ni-MH battery also has memory effect, nickel-cadmium battery is not clear. The most obvious memory effect of a lithium laptop battery

.

       No memory effect means that can be recharged several times, and even spent on each charge and not be hit too. Therefore the use of nickel-metal hydride batteries, generally do not consider the direct discharge and recharge.

       Of course, to extend the service life from the point of view, the charging and discharging about 30-50 times, you can do a depth of discharge to return to maximum capacity.

       AUDIOPHONE said that if the discharge is not so simple, then a small light bulb, until the light can not. Done so often over-discharge, but damage the battery.

       As we all know, a Ni-MH battery voltage is rated at 1.2V, just full of electricity when it is actually more than the value of, in general between 1.4-1.5V. With the use of voltage will gradually reduce, in general the use of occasions, when the voltage lower than 1V, it can not use basic, such as WALKMAN, CD
       DISKMAN, MD, MP3, DC, and so on. You can test their own "run out of power" is the number of battery voltage.

       However, if the occasion is the use of low-voltage, low current of the discharge will continue to use. We are talking about the depth of the discharge voltage means a general decline to between 0.85V-0.9V. Through low-voltage, low current discharge, this value, nickel-metal hydride batteries (including Ni-Cd) will be able to return to maximum capacity, to extend the service life. However, if the discharge continues, once lower than 0.8V battery may result in irreversible damage, but the impact on dell Latitude D620 battery , dell TD175 battery , dell TC030 battery

 life. That is why AUDIOPHONE method is not recommended, because you can not control the voltage to a certain value on the automatic cut-off. By the same token, nickel-cadmium batteries and nickel-metal hydride batteries are not recommended for the remote control like a small electrical current.


       Battery deep discharge of a better way is there to buy discharge of the functions of a special charger or electrical release. The easiest way is to AUDIOPHONE can, but must always use the value of the voltage reading table, once the danger to the region immediately to stop.


       If the series is, these simple battery voltage value multiplied by the number on it.

       Let me now turn to the batteries do not have to look long-term preservation and restoration methods. Attention, because of nickel-cadmium batteries and nickel-metal hydride batteries of different characteristics, the leaves of different methods of preservation. Nickel-cadmium batteries to be used to save electricity, so before you buy a new nickel-cadmium batteries is no power, the need to re-own. In general, using the correct method of charging, the charge is likely to take a 3-5 times in order to put the battery back to top form. The nickel-metal hydride batteries to be stored for a long time ago, the charge should be 80% (that we should count ourselves), and then save. That is why now buy a new nickel-metal hydride dell Inspiron 700m battery , dell G5345 battery , dell F5136 battery , dell D5561 battery , dell D7310 battery

dell Inspiron 9300 battery , dell G5266 battery , dell D5318 battery , dell U4873 battery , dell G5260 battery power came back somewhat, because manufacturers have been pre-charge, the turn-around time is too long to prevent the transport, electricity and batteries affected. Long-term preservation of the nickel-metal hydride batteries, first used more than electricity, and then the right way to take charge 2-3 times will be able to return to the top.

       Said again on the charge. In fact, the most difficult to master is the correct charge.
       From the charge current to charge, fast charge and there is the difference between a slow charge.
       Judging from the way of charge, charge current and pulse charge the difference.

       A lot of people have this kind of problem, whether slow or fast filling good and sufficient good.
       That we first take a look at what is filling fast and slow what is necessary and sufficient.
       With a nominal capacity of the battery 1C, in the 0.1-0.2C charge current charge for the slow,> 0.2C for the fast charge,> 0.8C for the ultra-fast charging, <= 0.05C the trickle charge is . To a 1400MAH the Ni-MH battery, for example, the charge current 140MA-280MA between slow to charge, and 280MA of the same charge current, battery 700MAH a while is filling fast. This shows that the fast charge or slow charge is a relative concept, and the capacity of the

       To return to the previous question, what is good or fast slow good? ! In fact, this is no fixed answer. Many people think that slow, and that will hurt the battery charge faster. Fast battery charge will hurt you? The answer is yes, but not because a lot of people think of "high-current battery charging harm." High current is at best an accomplice, the real reason is that fever, due to the high current caused by heat. The high temperature on the battery life significantly. Therefore, high current is not terrible, the headache is how to solve the heat problem.


       Having said that, it is necessary to introduce charging current and pulse charge of the concept. In the slow-charge, basically all the chargers are using the current method of charging, this design is simpler, easier to achieve. And because of the slow-charge current range, and will not cause the battery overheating. In the fast charge current issues, and then use the current method can not be avoided no doubt that the issue of batteries overheating, so the current method was abandoned. Pulse is replaced by the way, from the wave on, we can see that the charge current output is not a straight line, but sine wave. Crest, the current maximum, and then immediately into the trough, almost no current. The purpose of this design is to enable the battery has a recovery time, thus reducing the heat generated by high-current, so that the battery fever control in an acceptable level. Now the market to see more than 100 yuan rapid charger, the basic use of this method. But this type of charger is also used to determine the slope of voltage or delta law judge to determine whether the battery is full, full of once automatically transferred to the trickle charge, over time in order to avoid high-current sony PCGA-BP2NX battery , sony PCGA-BP2NY battery , sony PCGA-BP2R battery , sony PCGA-BP2V battery , sony VGP-BPS5 battery , sony PCGA-BP71 battery


Toshiba batteryof harm. Well-known example is the comparison of netizen each other's strong recommendation of cattle KN5060 charger. The charger in the major electronic markets have basically can take between 65-70, is not very sophisticated work, the results are good, belonging to the high cost of the product.


       Pulse mode to produce rapid charger is good, but for some abnormal requirements, such as rapid 1 hour charger, than that used 1C at this time to the ultra-fast charge current for charging too on the pulse of the law. Now the international community to adopt a basic law is to increase pulse depolarization combination. In short, the pulse is on the basis of law, when a sine wave of the upper half completed, the insertion of a short-term negative voltage of the cosine waves, is too large to offset the enormous heat of the current (depolarization), so that the battery Heat under control. This approach generally more professional in the charger, such as the model used by professional players on the use of chargers. Charger can do this kind often used 2C-3C on the current charge for the battery.

However, time is money point of view, rapid charger savings brought about by the time the effectiveness of injury than the battery life of about 10% of the much larger losses. That is why the rapid charger is very popular.


       Finally, chewing gum to talk about the battery. Many MP3 players on the MD player that you do not use the battery you chewing gum, or else the two of us playing time will be how much worse.
       This concept is wrong, gum cell battery is only a form, the essence remains the nickel-metal hydride batteries. In other words, a 1350MAH of chewing gum and a battery 1350MAH the No. 5 player Ni-MH battery effect is the same, there is no difference. In fact 5 nickel-metal hydride batteries have been 1800MAH capacity battery than chewing gum. Gum battery production, as far as possible in order to Walkman devices so thin, 5 battery specifications do not thin, and the 7-capacity battery specifications and Taiwan small, so small before Japan come up with this approach, not because of gum battery The capacity is particularly great. Chewing gum and batteries also have a nickel-metal hydride and nickel cadmium difference between the early nickel-cadmium batteries are also chewing gum but only 600MAH, not the current 7 Ni-MH battery large 750MAH
