Product – battery solutions, JiaJing l requirements
Can you really not familiar to battery, necessary to make up.
Also have memory effects nimh batteries, but no nickel cadmium battery. The most obvious effect of memory is not lithium batteries.
Memory effect is not obvious, multiple charging, means that even after use rechargeable and are unlikely to dozens of influence. Therefore, when used nimh batteries can generally don’t consider discharge and direct charge.
Of course, prolong service life Angle, 30-50 times in charge, can do a depth discharge, to return to the maximum capacity.
The AUDIOPHONE not discharge so simple, said a small bulbs, until no light can. So often, but excessive discharge damage cells.
Everyone knows that a quarter of nimh batteries rated voltage is in full in the first 1.2 V, when electricity is more than the actual value, generally in 1.4-1.5 V. With the use of, voltage will gradually decrease, in general, when the voltage 1V below, you can use, such as DISKMAN CD, MD WALKMAN, MP3, DC, etc. You can test the “finished” how much is the battery voltage.
But if the use situation is low voltage, small current will continue to use discharge. We say depth discharge generally refers to voltage drops to 0.85 V – 0.9 V. Through the low voltage, current, the value of discharge, nimh batteries (including nickel cadmium) is the biggest capacity can be restored to, prolong service life. But if we continue to discharge, once there than 0.8 V may cause irreversible damage to cells, but is influenced the battery life. This is why AUDIOPHONE methods are not recommended because you can’t control, voltage to a certain value will stop automatically. Similarly, nickel cadmium battery and nimh batteries are not recommended for remote small current appliances.
For battery depth discharge of good method is to buy the charger is discharge or the special function of the appliances. The most simple method is AUDIOPHONE can use the method, but must often read voltage, once the dangerous area to immediately stop.
If it is series, simple voltage value multiplied by the number of cells.
For a long time to preserve and restore the battery. Attention, because the nickel cadmium battery and nimh batteries, so save method of different characteristics in different leaf. Nickel cadmium battery is will use to save electricity, so everyone before buying new nickel cadmium battery is basic without electricity, need oneself to heavy. Generally speaking, the correct method of charging, probably need filling 3-5 times to let the battery restore to the best. But to long-term preservation before nimh batteries, should be charged to the 80% (the people should calculate), and then save. This is why now buy new nimh batteries electricity back a bit, because manufacturers have beforehand, prevent transport charge turnaround time is too long, and battery affected. Long-term preservation nimh batteries used in more than you will finish, again with correct methods were 2-3 times can be restored to the best state. (meal, hoho) continue!
Say again about the problem. Rechargeable In one of the most difficult charging is correct.
Charge from charging electric current to fast, slow rechargeable battery and the difference.
From charging ways, persistence and pulse of rechargeable battery flow.
Many people have such problems, whether good or slow quick charge is ready.
We first come to see what is what is slow and fast filling.
With a battery of nominal capacity for 1C, in 0.1-0.2 C for slow filling, charging current > 0.2 C > 0.8 for quick charge, for super fast charging of C, < = 0.05 C is Juan flow charging. In a day 1400MAH nimh batteries, for example, charging electric current in 140MA – 280MA between to slow, but also the battery charging electric current, 280MA for a quarter of the battery are 700MAH is fast. Thus, fast or slow filling filling is relatively concept, and the capacity of the battery itself has greatly.
Back to the previous question, what is good or slow? ! Actually it is not fixed. Many people think that fast, slow filling can damage cells. Filling can damage cells faster? The answer is yes, but the reason and not many people thought of “large current rechargeable battery” damage. Current, at the real reason is an accomplice is calorific, due to the large current caused by heating. High temperatures have great influence to the battery life-span. So say large current is not terrible, headache is to solve the heating problems. Now I say things – rechargeable batteries, and hope to help.
Product – rechargeable batteries belong to ni-mh battery (NI fd-mh nimh batteries battery) as an important part of family, has no-replacing function nimh batteries charging for a long time, and memory effects. Below are some problems for people who may help
1, nimh batteries have memory effects?
There is, but very small. Memory effect is not obvious, multiple charging, means that even after use rechargeable and won’t have too big effect, therefore, when used nimh batteries can generally don’t consider discharge and direct charge.
2, how to eliminate the nimh rechargeable batteries, memory effects?
Ni-mh battery charge about once every three months to deep discharge with discharge function, usually to discharge charger 1.0 V] can effectively relieve memory effects. If three months without discharge, actually your loss also have no, most 1 dollar a year section battery, you care? Discharge not necessary, can not.
Three time, before discharge battery?
Each time to recharge batteries before discharge is not necessary, and is harmful, because the battery life meaningless cut short.
4, new battery how to use?
Battery factory to the user, the time is long, sometimes one month, a half year, this time, because the battery may passivation, so the electrode material factory first used batteries are 3 ~ 5 times the best filling process, in order to completely eliminate put the electrode materials, the maximum capacity of the passivation. So suggest you use new batteries for the first time as far as possible a few times, put circular deep filling out [in battery first run, the MP3 sound listen on motionless] or discharge function of new battery charger light [because]] – a inside have electric charge, so again about three times. The new battery charging fever may be bad for the first time, after using a few times back to normal, may also appear in DC without full picture of no electricity, because it hasn’t activate the rechargeable battery charger, went in after charging indicator plucked charger plug on start charging again, so repeated 1-2 times, it can solve the above problem.
5, battery for long-term preservation before filling much electricity?
Ni-mh battery to long-term preservation before, should be charged to the 80% (the people should calculate), and then save. This is why now buy new nimh batteries electricity back a bit, because manufacturers have beforehand, prevent transport charge turnaround time is too long, and battery affected. Long-term preservation nimh batteries used in more than you will finish, again with correct methods were 2-3 times can be restored to the best state.
6 what is fast and slow filling and what is filling?
Fast or slow filling filling is relatively concept, and the capacity of the battery itself has greatly. With a battery of nominal capacity for 1C, in 0.1-0.2 C for slow filling, charging current > 0.2 C > 0.8 for quick charge, for super fast charging of C, < = 0.05 C is Juan flow charging. With a 2000MAH nimh batteries, for example, charging electric current in 200mA – 400mA between to slow, but also the battery charging electric current, 400mA for a quarter of the battery are 1800mAh is fast and our charger is 400 ma, charging electric current slow for long-term use rechargeable batteries.
