Phone lithium battery and its proper use
Durable goods belonging to the Li-ion laptop battery, so precious is not, we can be of calm, with no need for the expensive original Wall Décor & Hangings usually have a common brand to the Wall Décor & Hangings, the price of 15-20 yuan, save A direct charge to rely on mobile phones. Wall Décor & Hangings are filling fast (2-3 hours) and slow filling (10 hours up and down) of points, if the battery charge more quickly to choose better.
In addition, due to the characteristics of lithium batteries do not need to discharge and charge-off operation. Battery life depends entirely on how much of an effective charging time. In other words, even if you only use up half of the start of the charge has no impact on battery life.
1, awareness of memory effect
Battery memory effect refers to the irreversible failure of the battery, that battery failure can be re-back performance. Memory effect refers to a specific cell for a long time subjected to the work of the cycle, automatically keep this particular trend. The first definition of the nickel-cadmium batteries, nickel-cadmium batteries of the bag there is no memory effect, there are inspiron battery-sintering memory effect. And now the metal nickel hydrogen (commonly known as Ni-MH) batteries from the memory effect of the definition of restraint.
Nickel-cadmium batteries because of modern technology improvements, the memory effect has been substantially reduced, while the other is to replace the definition of the nickel-based batteries is the "lattice" is usually the case, the nickel-cadmium batteries by the two The effect of the combined effects, and the Ni-MH battery only by the "lattice" memory effect, and impact than the nickel-cadmium batteries for small.
In practice, the way memory effect on the Elimination of strict norms and operation of a process, improper operation would be counter-productive.
For nickel-cadmium batteries, regular maintenance is a deep discharge on a regular basis: the use of every month (or 30 cycles) to carry out a deep discharge (discharge to 1.0V / per session, foreigners call it exercise), usually used up as much as possible is the use of BAT1194 Or shut down, and other means can be used to alleviate the effects of memory formation, but this is not exercise, because the equipment (such as mobile phones) will not be used 1.0V / per session before the shutdown, it is necessary specialized equipment or line to complete this Work, but fortunately many of the Ni-MH battery charger with all the features.
For a long time not to carry out the exercise nickel-cadmium batteries, because of the cumulative effect of memory, can not restore the capacity for exercise, then you need to better discharge (called a foreigner recondition), which is a very small current to the battery for a long time 0.4V to discharge each of a process, the need for professional equipment.
For Ni-MH battery, exercise carried out by the frequency of about once every three months to ease the effective memory effect. Ni-MH battery because the cycle of life is far lower than the nickel-cadmium batteries, with almost no recondition this method.
Recommendation 1: Every time charge of battery discharge before it is not necessary, but also harmful, because the battery life short by a senseless.
Recommendation 2: The next resistance of a battery is negative for the discharge is not desirable, the current can not control, easy to put off 0V, and even led to the series of batteries U1544 polarity reversal.
2, the battery you need to activate
The answer is the need to activate the battery, but this is not the users do. I visited the lithium-ion battery manufacturers, lithium-ion battery factory in the past go through the process as follows: lithium-ion battery electrolyte impart SHELL - Seal - into, that is, charging voltage, and then discharge, so for a few cycle, so that Full infiltration electrode electrolyte, fully activated in order to meet the requirements of capacity, the activation process is - at capacity, is testing the capacity of the battery to select a different performance (capacity) batteries are classified, the level of cell division, such as matching capacity . So out of the lithium-ion battery to the hands of users had already activated.
We used nickel cadmium batteries and nickel-metal hydride battery is activated into the case after the factory. Some of the batteries need to activate the battery in the process of opening, re-activated after sealing, that process may be only batteries manufacturer to complete.
Here there is a problem that is the factory of the battery cell to the hands of the user, this is sometimes a very long time, is short on a long six months, this time because the 3R305 electrode materials will be passive, so the manufacturer recommends that first-time Battery for the best 3 - 5 times completely filling the process of release in order to eliminate passivation of the electrode material, the maximum capacity.
In 2001 the promulgation of the three on the nickel-metal hydride and nickel cadmium and lithium-ion batteries in the national standard, and its initial capacity of the testing are clearly defined, the battery can charge 5 deep deep release, once in line with the requirements To stop the trial. This is a very good explanation of this phenomenon I am talking about.
So called "second-activated" can, first-time users of the "new" C1295 charge as much as possible to carry out several deep-release cycle.
However, according to the author's test (for lithium-ion battery), the storage period in the 1 - 3 months of the lithium-ion battery, and it's Fang deep charge deep processing cycle, the capacity is almost non-existent.
