metal hydride battery of new products has accelerated the procurement of all heat

Many friends through the Ni-MH battery and battery box CRAB brands, with labels for different products purchased more than match the nickel-metal hydride batteries.

Has introduced many domestic and foreign manufacturers use nickel-metal hydride battery of new products has accelerated the procurement of all heat, of course, her unique "qualities" such as energy density, charge more often, memory effects are small, non-mercury cadmium and other harmful Metal series of advantages and achievements of the Ni-MH battery position in the market continues to climb.

With all the hands of the NiMH battery a steady increase in the number of scientific leap into the use and maintenance of our attention has gradually come to sight. As we all know, brand Ni-MH battery life can be charged according to the official claim that 500-1000 times, in fact, this is a good value, often failed to produce such life. But as long as a reasonable use of the charger, and more in-depth understanding of nickel-hydrogen batteries, we can still do her "longevity."

1. In general, the new nickel-metal hydride batteries contain only a small amount of electricity we purchase to charge first and then re-use. But the relatively short time if the battery factory, power is adequate, recommended first use and then 

 

 recharge.

2. Buy a new nickel-metal hydride batteries generally go through 3-4 times the charge and the use, performance can play to the best state, many of my friends encountered the first charge a small problem for example, after the first charge did not imagine the number of PP film so much ah? In the 3-4 times after charging and the use of all solved.

3. Although the Ni-MH battery memory effect is small, still recommend you try to recharge after each use, complete, and is filled with one-time, do not charge for a while and then used for a charge. This, however, "longevity" Oh, the important point.

4. Charging the battery, charger around to pay attention to the heat, too deliberate in what is no need for the fan blowing, but note that the charger should not put too much junk around. Ordinary users to use the battery in the process, often without special storage battery pack; users to replace the battery, the battery will be used to conveniently put away in nature, regardless of where the place is clean, wet. This result is the battery get dirty easily, easily contact such as keys, and metal  contacts, easy to damp, which are the enemy of batteries. Recommendation: Users should set up a special place point the battery and keep the battery clean. To avoid power loss and other problems, to keep the battery contact points at both ends and the internal battery DELL Laptop Battery HP Laptop Battery lid clean and, if necessary, use a soft, clean dry cloth graze.

5. A long time when not in use, remember to remove the battery from the battery compartment, placed in dry conditions recommended by the battery box into the card, to avoid short-circuit the battery.

6. Long Ni-MH battery unused in storage a few months later, the battery naturally into a "sleep" state, the battery life greatly reduced. If Ni-MH battery has been placed for a long time, I suggest you start with a slow charge is appropriate to charge. Another key issue involved here: the nickel-metal hydride batteries, the battery should be fully discharged and then save, save, or charged? These two very different perspectives, what it should be used? Many people think that we should adopt the former, but I think that save the battery charged is reasonable. Because: It has been tested, Ni-MH battery to the best conditions for preservation is 80% charged. This is because self-discharge NiMH battery is larger (10% -15% a month or so), if the battery is fully discharged and then saved a long time do not use the battery self-discharge phenomenon will cause the battery over discharge, will damage the battery. Do not believe? Do you think about the new Ni-MH rechargeable batteries to buy is not all there is electricity, which is the truth. Tip: compare, correct the erroneous views, starting from the maintenance of the battery in the right direction, otherwise it will backfire.

7. There are a lot of friends posting asked how to discharge Ni-MH? Asked experts in various cells, results in a unanimous conclusion to remind friends. Do not try to nickel-hydrogen battery discharge, over-discharge may cause charging failure to do so against much larger than Ni-MH battery memory effect itself!

8. Multimeter self-test battery is full or not. General NiMH battery before charging, the voltage at 1.2V below the normal voltage of 1.4V after full around. We to judge, also very easy to judge the state of the battery IBM Laptop Battery SONY Laptop Battery.

9. Chargers divided into fast charge and slow charge. Slow flow of a small charge, usually around 200mA, such as our common charge current is about 160mA. Her long charging time, charging 1800mAh Ni-MH battery to 16 hours or so. Although time is a bit slow, but very full charge will be sufficient, and not to hurt the battery. Fast charge current is usually in the more than 400mA, the charging time was significantly reduced number of 3-four hours can handle, and won everyone's favorite. Many kinds of fast charge different prices. Therefore, we often have questions about charging the same fast, very different then the price Why? Good charger, especially with a good fast charge are protected against over-charging function, for example, we commonly Need Panasonic BQ 390 charger is particularly outstanding in this regard, excellent software design capacity of the chip in the battery, they to damage the battery fast charge reduced to a minimum.

10. A conflict: Slow charge the battery but the charge does not hurt too long; fast charge can save time, but has hurt the battery, even if the surface is the World Need the best Panasonic BQ390 charger only very good level of harm reduction , but not totally avoided. Contradiction can be resolved is to buy a quick charge and a slow charge. Charge with a fast charge time, for example 5.10 times after the switch to slow rechargeyour batteries once or twice. This performance of the battery again to return to top form.

11. Battery used battery usually means four or six together, and this time, to maintain the balance of each cell is important, or else because of a battery problem has affected the work of the entire battery pack. First of all, the battery capacity to ensure consistent, the best choice to buy the same brand of the same type of battery at the same time. Then, the internal battery power to maintain consistency, simply, is that electric or battery is full, or are empty. If there are more and more composed of groups of battery cells, can try to "select" look. Specific means, the capacity, voltage and other parameters similar to the battery cells in series into a set of batteries, due to inadequate conditions, in general, what is done and the measured point and good electrical impulse voltage and the voltage on it.
