A lot of friends through the Ni-MH battery and laptop battery box CRAB brands, with labels for different products for more than a match for the purchase of nickel-metal hydride batteries.

A number of domestic and foreign manufacturers continue to introduce the use of nickel-metal hydride battery of new products we have to speed up the procurement of heat, of course, her unique “quality”, such as energy density, the number of charge, a small memory effect, non-cadmium mercury and other harmful Metal advantage of a series of achievements have a nickel-metal hydride batteries in the market rising.

With everyone in the hands of the nickel-metal hydride batteries in the number of continuous increase in the use and maintenance of science gradually into the line of sight of the concern in the past. As we all know, brand Ni-MH battery life according to the official line is that the charge can be 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 Ni-MH battery, we can still do her “longevity.”

1. Under normal circumstances, the new nickel-metal hydride batteries contain only small amounts of electricity, we must first purchase and then charge for use. However, if the battery factory relatively short time, the electricity is enough to recommend the use of first and then charge.

2.’s Purchase of the new nickel-metal hydride batteries generally go through 3-4 times the charge and the use of performance in order to play the best, a lot of friends met for the first time charge of the minor problems, such as charging for the first time after the shooting did not imagine the amount of PP You so much? In the 3-4 times charger and use after all be solved.

3. Although the Ni-MH hp battery memory effect of the small, we still recommend the use of as much as possible every time after the end charge and is full of one-time, I will not be sufficient for a moment and then charge. However, this “longevity” Oh, that’s important.

4. Rechargeable battery, charger should pay attention to the surrounding heat, too deliberate what the fan is no need to blow, but bearing in mind that the charger is not to put too much around the debris. Ordinary users in the use of batteries, the batteries are not the exclusive use of storage bag; users to replace the battery after the customary battery placed at random, regardless of whether or not the release of the place clean, damp. The consequences of such a battery is easy to dirty and easy contact with the metal such as  , and other key contacts easily damp, and these are the enemy of batteries. : Users should set up a special cell to place, maintain and clean the battery. In order to avoid problems such as loss of electricity to keep the battery at both ends of the contact point and the internal battery lid clean and, if necessary, use a soft, clean dry cloth graze.

5. Not for a long time, remember that the battery cell from the warehouse out, under dry conditions recommended card into the Pavilion DV4000 battery  box, to avoid short-circuit the battery.

6.’s Not a long-term nickel-metal hydride batteries will be stored in a few months later, the battery into the nature of a “dormant” status, significantly reduce battery life. If the Ni-MH battery has been placed for a long time, I suggest you first slow to carry out sufficient charge is appropriate. Here is another key issue involved: Ni-MH battery, the battery is fully discharged and then save, or save live? These two very different point of view, it should be adopted? Many people believe should be the former, but I think a more reasonable to preserve the battery charged. Because: It has been tested, Ni-MH battery to preserve the best condition that charged about 80% of preservation. This is because Ni-MH battery self-discharge of a larger (10% -15% in a month or so), if the battery completely discharge and then preserved for a long time not to use, the battery self-discharge phenomenon will result in excessive discharge of the battery, Will damage the battery. Do not believe it? What do you think of buying a new nickel-metal hydride rechargeable batteries is not all there is electricity, which is the reason. : More compared to rectify the wrong point of view, from the start in the right direction maintenance batteries, or else they will backfire.

7. Have made many friends in the post asked how the Ni-MH conduct discharge? The expert asked about the number of batteries, reached the same conclusion to remind friends. Do not try to nickel-metal hydride batteries, rechargeable lead-off put the failure to do so against much larger than their own Ni-MH battery memory effect!

8. Multimeter battery is full of self-test or not. General in charge Ni-MH battery, 1.2V voltage below the normal voltage in full after about 1.4V. We judge this, it is easy to judge the status of the Presario V2000 battery .

9. Charger can be broadly divided into fast and slow-filling charge. Slow flow of small charge, usually around 200mA, such as our common charge current is 160mA or so. Her charge for a long time and charging the 1800mAh Ni-MH battery to 16 hours or so. Although time is a bit slow, but the charge would be sufficient enough and did not hurt the battery. Fast flow usually charge more than 400mA, charging significantly reduce a lot of time ,3-4 hours you can get, and everyone’s favorite to win. Many types of fast filling, the prices vary. So often we all have doubts, are filling fast, and why the price is a big gap in it? Good charger in particular are filling fast with a good anti-over-charge protection, for example, we the Panasonic common charger Need BQ 390 in this regard was especially outstanding, excellent software, chip design capabilities in the battery charge, Also quick to charge the battery for damage to a minimum.

10. There is such a conflict: Slow injury is not sufficient battery charge time is too long, however; fast charge time can be saved, but the batteries have hurt, even if the world is the best surface of the Need for Panasonic BQ390 charger can only be good to reduce the extent of injury , But can not be completely avoided. This contradiction can be resolved is to buy a quick charge and a charge slowly. With sufficient speed and sufficient period of time, for example, at 5, 10, Chong Chongdian slow to switch to one or two. This will also return to the performance of battery-top condition.

11. Batteries are generally used battery, that is, 4 or 6 series, this time to maintain the balance of each cell is very important, otherwise, because of a battery problem affected the entire battery pack. First of all, to ensure that the battery capacity, the best choice of the same brand of the same type of battery at the same time to buy. Then, to keep the internal battery power, said simply, is that the Armada E500 battery  power is either full or empty. If there are more cell group composed of a number of batteries, you can try to “select” look. That is specific to capacity, similar to parameters such as voltage battery series into a single set of batteries, due to inadequate conditions, under normal circumstances, let us test after the end point of voltage and power good voltage washed it.

12. To talk about the final charge and discharge.

The high-grade NI-MH battery charger using a detection-DELTA V battery voltage to determine whether the battery is full. When the battery voltage discharge curve and a little bit similar to the beginning of a more rapid rise, followed by the slow rise until sufficient good, fast start and voltage drop in the rate of decline is not great. Before commonly used nickel-cadmium batteries are also similar, but the decline in the speed and range than the NI-MH are great. The largest number of chargers on the market (that’s less expensive) is often used in value-charge pressure, such as Po-old GP is the 1.4V charge voltage value, that is, into the battery when the 1.4V voltage in the absence of the poor, charging the end of . Such an outcome is often not the battery is full, especially compared with some of the old battery, due to increasing resistance, the real increase in battery on a lower voltage. This charger current and often smaller, often have to charge more than 10 hours. The use-DELTA V automatic cut off of the charger, because it can accurately control the charging time, it can be more reliable to use the current charge. Current nickel-metal hydride rechargeable batteries for the damage we did not imagine the stakes, the opposite, the use of DC now, more high-current charge. First of all, is a matter of time, do not have to speak. Then, Ni-MH Armada M700 battery  has a characteristic that you charge the greater the current, it can release the greater the current, DC power is a tiger, not a small current, relatively speaking, therefore, the use of relatively large Current charge is a wise choice, can increase battery _ clean. 5, the general charge current should not exceed 1.5C, C for the battery capacity is 1000MAH batteries, not more than 1.5A. I normally charge for use of 0.5C (my current adjustable charger). Discharge, under normal circumstances, DC after the black screen will be able to take charge of, NI-MH little memory effect. But after a period of time, as well as to balance the battery cell activation, to control the discharge of the battery voltage termination. NI-MH battery voltage of the termination of 0.9V, the discharge time careful not to over-discharge, on each battery 0.9V when you can stop the discharge. NI-MH battery has not tough nickel-cadmium batteries, the charge had been released and are more sensitive to high temperatures. Charge-discharge temperature. In general, do not let the battery temperature higher than 45 degrees. The battery is full, the batteries will be fever, a high current when the temperature should be about 42 degrees and not more than 45 degrees, otherwise life will quickly reduce the battery internal resistance will increase. In addition, the battery charge after a high temperature, cooling, and so only after their charge, the money would also charge the battery cooling, and so on. Not long after the re-use, the best sufficient to reactivate the Armada V300 battery  release several times. The use of normal time to pay attention to maintaining the integrity of packaging paper, there can not be broken in order to avoid a short circuit. Not tempering the impact of the battery, do not fire, and so on.
