Weak current College】 【new battery use and maintenance of】.

As everyone in the hands of the Ni-MH battery number constantly increases, the use and maintenance of Science also gradually into the sight of public concern. We all know, brand NiMH battery life press official claim can charge 500-1000 times, actually this is only an ideal value, often up to such a life. But as long as the reasonable use charger, more in-depth understanding of Ni-MH battery, we still can let her do the "longevity".

1. in General, the new Ni-MH battery only contain a small amount of power, is leaving the factory, the factory test is on battery power!! recommended first use and then charging with a clean, begin charging! first must charge 24 small four, activate! if you do not have virtual power, more can be directly activated!!

2. new PCs Ni-MH battery usually after 3-4 times the charge and use performance to play to the best State, many of my friends first charging small problems encountered, for instance, after the first charge did not beat PP number imagined so many? in 3-4 times the charge and use it is solved. If conditional, it's best to charge for 24 hours, activate 3-4 times can extend battery life!

3. While the Ni-MH battery memory effect is small, still recommend it to every use after rechargeable, and is a one-time charge and a full, do not use for a while and then filled. This is the "longevity" important point oh.

4. the battery is charging, it is necessary to pay attention to the charger around the heat, so deliberately what fan no necessary, but it should be noted that the charger around not to place too much junk. Average user using the battery, the battery is often no dedicated storage package; users replace battery, the battery will be used to put behind you, regardless of the place is clean, damp. Such a consequence is that the battery is easy to clean, easy-to-metal contact points such as keys, and other contact, easily gets wet, but these are the enemy of the battery. Recommendation: customers should set up a private placement, the battery and keep the battery clean. In order to avoid problems such as loss of power occurred, keep the batteries from both ends of the contact points and the battery lid internal clean, if necessary, use a soft, clean, dry cloth to wipe gently.

5. long unused time, remember to remove the battery from the battery compartment that placed the dry environment recommendation into brand battery box, you can avoid short-circuit the battery.

6. long-term unused NiMH batteries will be kept for a few months later, the battery of nature into a "sleep" State, the battery life is significantly reduced. If you place the NiMH batteries have a very long time, advise you to use slow charger for charging. This involves another key challenge for Ni-MH battery, the battery is fully discharged and then save, or save live? this two completely different views, should I take? many people think should be the former, but I do think the battery charged save more reasonable. Because: it is a test, Ni-MH battery save best conditions is charged 80% of the saved. This is because the Ni-MH battery self-discharge is large (a 10%-15% or so), if the battery is fully discharged and then save that for a long time does not use the battery self-discharge phenomenon will cause the battery's discharge, can damage the battery. Do not believe that do you think about the new PCs Ni-MH rechargeable battery is not all there is electricity, which is the reason. Recommendations: more comparison, correction of errors of perspective, from the right direction to start maintenance battery, otherwise they will be counterproductive.

7. There are a lot of friends to post questions, how to discharge NiMH? asked many battery experts, came to the unanimous conclusion remind friends. Try not to discharge the NiMH battery, over discharge leads charge failure, doing harm than Ni-MH battery itself memory effect!

8. the multimeter with battery or not. General Ni-MH battery charging voltage in 1.2V before, it fills up the following normal voltage in 1.4V. All of this judgment, it is very easy to determine the status of the battery.

9. the charger is mainly divided into fast charger and slow filling. Slow charging current is small, usually around in 200mA, such as our common charging current is about the 160mA. Her charge time of long, 1800mAh Ni-MH battery charging to 16 hours or so. Time is slow, but charging will charge a foot, and does not damage the battery. Fast charging current is usually in more than 400mA battery charging time significantly reduce many, 3-4 hours to get, also won everybody's favorite. There are many kinds of fast charge, the price is not one. So we often have questions, and is why the fast charge, the price considerably? good charger especially good fast charge with the charge against excessive protection features, excellent chip software design capabilities in the battery, put the fast charge battery damage are minimized.

10. battery use generally is the battery pack is 4 or 6 series, this time to maintain the balance of each battery is very important, otherwise because of a problem with the battery section affect the whole battery pack. First of all to ensure that the battery capacity, it is best to choose the same brand of the same model at the purchase of the battery. Then, to keep the battery internal power match, simply put, is the power or battery pack is full or empty. If you have more battery composition number group battery pack, you can try the "selection". The specific means, capacities, voltage, and other parameters similar to batteries monomer in series as a set of batteries, due to insufficient conditions, typically have your finished point voltage and voltage electric punching well.

11. finally talk about the charge and discharge.

Upscale NI-MH charger uses-DELTAV detect battery voltage to determine if the battery is full. Battery charging voltage curve and discharge is somewhat similar to the start time is faster rise, rise, wait until after the slow charging, voltage drop, began rapidly declining range only. Before common nickel-cadmium batteries is similar, just drop in speed and range than NI-MH. While the market most charger (cheaper) are often used for pressure charging, such as old GP charger Po is 1.4V scale pressure, that is, when the battery ran to 1.4V because there is no voltage difference, charging. This result, often the battery is not full, especially some older batteries, because internal resistance increase, real plus in the voltage on the battery. And this charger current tends to smaller, often charging 10 more hours. To use the automatic cut off-DELTAV charger, can accurately control the charging time, so you can compare reliable use high current charging. High current charging for Ni-MH battery damage did we imagine an interest, on the contrary, the use of DC now requires high current charging. First of all a matter of time, needless to say. Then, there is a characteristic of NiMH batteries is that you charge current increases, it can evolve the current, DC are electric Tiger now, current is relatively small, therefore the use of relatively large current charge is a wise choice, you can let the battery more clean. General 5 charging current must not exceed 1.5C, C for battery capacity 1000MAH battery is, do not exceed 1.5A. I normally use for charging 0.5C (my charger adjustable current). Discharge connection, General, DC black screen after take charge, NI-MH memory effect is small. But at a period of time after use, as well as to balance the battery, activate the battery, to control the battery discharge end voltage. NI-MH termination voltage of battery 0.9V, discharge time careful not to over-discharge to each battery can stop 0.9V discharge. NI-MH battery no nickel-cadmium battery a, superfluous and high temperatures are more sensitive. Charge and discharge temperature. In General, do not let the battery to temperatures above 45 degrees. When the battery is full, the battery will generate heat, high current full time temperature should be around for 42 degrees, not more than 45 degrees, otherwise life will soon reduce the battery will increase. Also, after charging the battery temperature is high, and so on cooling is on its charging, charging money or have to wait for the battery to cool. Long time no reuse, it is best to charge and discharge it over and over again to reactivate the battery. Usually used when it is necessary to pay attention to maintain the integrity of the packaging skin can not be broken to avoid short circuit. Don't put up with impact battery, do not fire, etc.
