Experts tell you the correct way of using the lithium battery -
Understanding memory effect
Experts tell you know the correct way of using the lithium-ion batteries memory effect article battery memory effect refers to the reversible battery failure, namely the performance of the battery can be reactivated after failure.
Memory effect refers to the battery for a long time through specific work cycle, tend to keep this particular automatically.
The first definition in nickel cadmium battery, bag of cadmium nickel battery no memory effect, sintering type battery memory effect.
Now the nickel metal hydrogen (
Commonly known as nimh)
Battery is not bound by definition the memory effect.
Because modern nickel cadmium battery technology improvement, the memory effect has been greatly reduced, and the other a phenomenon to replace the definition, nickel-based batteries' lattice change, usually, nickel cadmium battery comprehensive influence by these two effects, while nimh batteries is only affected by 'lattice change' memory effect, and the nickel cadmium battery for small effect.
In practice, the method of elimination of memory effects have strict specifications and an operating process.
Improper operation will be counterproductive.
For nickel cadmium battery, the maintenance of normal is deep discharge on a regular basis: the average use for a month (
30 or loop)
A deep discharge (
Discharge to 1.
0 v/per day, foreigners called exercise)
, common use is to use photovoltaic cells or use the means such as shutdown can reduce the formation of the memory effect, but this is not exercise, because the instrument (
Such as mobile phone)
1 is not used.
0 v/only to turn it off every day, must be special equipment or line to finish the work, but luckily many of nimh battery charger with this function.
For no nickel cadmium battery to exercise for a long time, because the cumulative memory effect, can't reply in exercise capacity, then you will need to deeper discharge (
A foreigner said recondition)
With a small current, which is a long time for the battery discharge to zero.
4 v each section of a process, need professional equipment.
For nickel metal hydride batteries, exercise on the frequency of about once every three months can effectively relieve the memory effect.
Because the cycle life of nimh battery is below the nickel cadmium battery, with little recondition this method.
Bring about suggestion 1: every time there is no need to charge the battery before discharge, and it is harmful, because useless shorten the life of the battery.
Bring suggest 2: use a resistor connect is the cathode of the battery discharge is not desirable, can't control current, easy to 0 v, even lead to series of battery cell polarity reversal.
Bring 3: can consider to use lithium-ion batteries, lithium-ion battery has no memory effect.
Electric car lithium-ion batteries, lithium batteries will choose.
A focus on electric lithium battery research and development and sales of manufacturers.
