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 laptop 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 its best.
3. Although the Ni-MH 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” an important point.
4. Rechargeable battery, charger should pay attention to the surrounding heat and not to put too many chargers around the debris. The battery contacts to avoid oxidation. If the application of oxidation of paper or cloth wipe, do not sandpaper or grinding wheel, or else they will lead to more serious oxidation.
5. Not for a long time, remember that the battery cell from the warehouse out, under dry conditions, the recommendation into the battery box, to avoid short-circuit the battery contacts and oxidation.
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 presario battery life. If the nickel-metal hydride batteries have 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. 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 Presario 900 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 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. Charge for a long time to the 1800mAh Ni-MH battery to 16 hours or so. Although time is a bit slow, but will charge the full charge is enough, and do 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, such as the period of hot-selling LCD Panasonic BQ-830 smart charger rapid charger in this regard was especially outstanding.
10. Slow injury does not charge the battery charge time is too long, however; fast charge time can be saved, but the batteries have hurt, even if the surface is the best of the best the world can only be a good charger to reduce the extent of damage, 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 Presario R3000 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 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 finished after the charge voltage and power good voltage on 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 think much, on the contrary, now that the use of small electrical appliances, and more high-current charge. The first is a matter of time, do not have to speak. Then, Ni-MH asus battery has a characteristic that you charge the greater the current, it can release the greater the current, electrical 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. 0.5C can be used to conduct charge. Discharge, under normal circumstances, after the black electrical charge can be taken up, NI-MH little memory effect. But after a period of time, as well as to balance the use of batteries, battery-activated, 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, the A2 battery internal resistance will increase. After the battery charge a higher temperature, cooling, and so on before use.
Battery for a long time do not have to re-use, the best sufficient to reactivate the 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. Do not tempering the impact of the battery, do not burn.
