How to activate a battery without charging for a long time

Brand nickel metal hydride battery service life of press officials say can charge 500-1000, in fact this is only an ideal value, often short of such a life.But as long as reasonable use charger, more in-depth understanding of Ni-Mh batteries, we will still be able to let her do it "longevity".1. In general, new Ni-Mh batteries contain only a small amount of electricity, when you buy to recharged and then use.But if the battery factory time is shorter, electricity, recommend use before recharging.2. New Ni-Mh batteries typically after 3-4 times of charging and use, to play to the best performance, met many friends first charging small problems, for example, after the first charge on PP number did not imagine so much?After three to four time charge and use are solved.3. Although the Ni-Mh battery memory effect is small, still recommend recharging after each use as far as possible, and is a one-off, do not charge in a while and then filling in a minute.This is a "longevity" the important thing ah.4. When the battery is being charged, pay attention to the heat around the charger, what fan blowing too sedulous no necessary, but note that the charger don't place too much stuff around.Ordinary users in the process of using battery, battery often do not have a dedicated storage bag;After the user in the replacement battery, tend to put the battery with good, and whether or not the place where a clean, damp.The consequence of this is battery stain easily, contact easy and metal?Such as the key?Wait for contact, easy to be affected with damp be affected with damp, and these are the enemy of the battery.Suggestion: users should set up a battery special placement, and keep the battery clean.In order to avoid the problem such as power loss, keep the contact point at the ends of the battery and battery cover internal clean, when it is necessary to use soft, dry cloth gently wipe clean.5. Long time no, remember to remove the batteries from the battery, put in dry environment recommended in the card battery box, can avoid the battery short circuit.6. No nickel metal hydride batteries for a long time can deposit in a few months later, nature into a state of "dormancy" batteries, battery life is reduced greatly.If the Ni-Mh batteries have been placed for a long time, it is advisable to suggest you use first slow charger to charge.Here involves another key issue: for nickel metal hydride batteries, battery should be completely discharge and then save, or charged to save?The two completely different points of view, should adopt what kind of?Many people think that the former should be adopted, but I think it is the battery charged preservation is quite reasonable.Because: according to the test, nickel metal hydride batteries charged about 80% is the best condition of preservation.This is because the Ni-Mh battery self-discharge larger (10% - 15% a month), if the battery discharge completely before preservation, for a long time not to use, the battery self-discharge phenomenon will cause the battery over discharge, can damage the battery.Don't believe it?When you think about new buy is nickel metal hydride rechargeable batteries and electric, all of it is for this reason.Suggest: comparison, more correct point of view, and from the direction of the correct maintenance of the battery, otherwise it will backfire.7. There are a lot of friends ask you post, how to discharge the Ni-Mh?After asking many battery experts, a consistent conclusion remind friends.As far as possible not to Ni-Mh battery discharge, discharge will cause the failure of charging, the harm is far greater than Ni-Mh battery memory effect itself!8. A multimeter self-checking batteries or not.Generally Ni-Mh battery before charging, voltage below 1.2 V, full of the normal voltage at around 1.4 V.You judge, also it is easy to judge the state of the battery.9. Charger mainly divided into fast and slow filling.Slow charging flow is small, usually in about 200 ma, such as our common charging current is around 160 ma.Her long charging time, charging, 1800 mah ni-mh battery to 16 hours.Although time is slow, but the charge will be charge is enough, and does not hurt the battery.Fast charging circulation often are more than 400 ma, charging time significantly reduced a lot, 3-4 hours, you could just won everyone's favorite.Quick charge is a lot of more phyletic, the price is different.So people are often in doubt, with quick charge, why the price differs very big?Good charger especially good fast with the function of preventing overcharge protection, for our common panasonic acura charger BQ390 performed particularly well in this aspect, excellent chip software design on the battery, and the quick charge damage to the battery down to a minimum.10. The contradiction appeared: slow charge but it does not hurt the battery charging time is too long;Quick charge can save time, but has damage to the battery, even if is the world's best panasonic acura charger BQ390 also can only be good to reduce the harm degree, but cannot avoid completely.Solution to the contradiction is to buy a quick charge and a slow filling.With fast was a period of time, after 5, 10, to switch to slow charge once or twice.And thus the performance of the battery back to his best.11. When the battery is usually battery pack, is 4 and 6 together, at that time, keep the balance of each cell is very important, because otherwise one of the battery issue and affect the work of the whole battery pack.First of all to ensure the battery capacity, the best choice model at the same time to buy the same brand of batteries.Then, to keep the agreement of the capacity of the battery inside, simply put, is the electric battery or is full, or empty.If have more battery composed of several group of battery pack, can try to "hits".Concrete that is to say, will be similar to the results of the parameters such as capacity, voltage battery monomer series into a set of battery pack, caused by a lack of conditions, usually measured after a lower point of voltage and good electric voltage.12. The last talk about charge and discharge.

High-grade NI MH of charging device is - DELTAV detect the battery voltage to judge whether the battery is full.Battery charging and discharging voltage curve is a little similar, is rising faster at the beginning, then slowly rising, wait for good times, voltage began falling fast, just drop in the magnitude of the is not very big.Before common nickel cadmium battery is similar, but the pace of decline and amplitude is larger than NI - MH.And the most chargers on the market (cheaper) often used is scale voltage charge, such as old GP charging treasure equilibrium voltage is 1.4 V, was rushed to the 1.4 V a battery because there is no voltage difference, the charging is over.As a result, often is not full of batteries, especially some old batteries, due to internal resistance increases, really add on the battery voltage is lower.Often small, and the charger current charging tend to be more than 10 hours.And use - DELTAV automatically cut off the charger, being able to accurately control the charging time, so you can compare the use of reliable large current charging.Large current charging for nickel metal hydride battery damage is not everybody imagination of interests, on the contrary, the use of DC now, need large current charging more.The first is a matter of time, don't speak.Ni-mh battery has a characteristic, then, that you charge the greater the current, it can release the greater the current, DC electricity eating tigers, now have no small current, so relatively use relatively large current charging is a wise choice, can let the battery put more clean.General charging current should not exceed 1.5 C, 5 C for battery capacity, is the 1000 mah battery, not more than 1.5 A.I usually use 0.5 C to charge (my charger adjustable current).After discharge, under normal circumstances, the DC black screen to take charge and NI - MH memory effect is very small.But over a period of time after use, and to balance the cells, activate cells, to control the battery discharging termination voltage.NI MH battery - termination voltage of 0.9 V, discharge notice don't discharge, in each section 0.9 V battery can stop discharge.NI MH battery there are no nickel cadmium battery, over charge and heat are more sensitive.Charge and discharge temperature.In general, don't let the battery temperature is higher than 45 degrees.Batteries, the battery will be fever, large current with temperature should be about 42 degrees, not more than 45 degrees, otherwise life will soon be lower, the battery internal resistance will increase.Also, charge the battery temperature is higher, and after I can charge the battery for its cooling, charging money also to wait for the battery to cool.After long time need not, the best filling put a few times to activate the battery.Use at ordinary times should pay attention to keep BaoZhuangPi complete, can't there is any breakage, so as to avoid short circuit.Don't break the impact battery, don't fire, and so on.
