The proper use of lithium-ion batteries.

The proper use of lithium-ion batteries.
The proper use of lithium-ion battery should note the following points:

To avoid the use of harsh conditions, such as: high temperature, high humidity, long hours under the summer sun exposure and so on, to avoid the battery Laptop Battery into a fire;

Installed, remove the battery, should ensure that electrical appliances in a power-down state; the use of temperature should be maintained at between -20 ~ 55 ℃;

Avoid prolonged battery "placement" to stop using the electric appliances in China;

The use of lithium-ion battery

1, how a new battery charging,

The use of lithium batteries should be noted that a period of time after the battery is placed into hibernation, lower than normal capacity at this time, use of time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycles the Latitude D820 battery can be activated to restore to normal capacity. As the lithium battery's own characteristics, its decision is almost no memory effect. Mobile phones so users of the new lithium battery in the activation process does not require special methods and equipment. Not only the theory that, from my own practice point of view, from the outset on the use of standard method of charging that "activation" approach is the best.

For the lithium battery "activate" problem, many say is: recharge time must be more than 12 hours, repeated three times to do in order to activate the battery. This "The first three charging more than 12 hours to charge" was obviously from the nickel battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that a beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics are very big difference, but also very clear to tell you that I have gone through all the serious official stressed that technical information and charge-off will discharge lithium batteries, especially lithium liquid ion TD175 battery causing great harm. Accordance with the standard charge and therefore the best time and the standard method of charging, in particular, not to carry out more than 12 hours of super-long charge.

In addition, lithium batteries or the charger will automatically stop after the battery is full charge, there is no electricity nickel charger for 10 hours of the so-called "trickle" charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change and the quality of fail-safe, so your battery will be a long-term at the brink of danger. This is also another charge against the chief reason.

In addition, another aspect can not be ignored is the lithium battery is also not suitable for over-discharge, over-discharge of lithium batteries is also very unfavorable.

2, normal use should be when to start charging

Often see this argument, because the number of charging and discharging is limited, so phone the battery should be used up as much as possible recharge. But I found one on the PC764 lithium-ion battery charge and discharge cycle test table, on the cycle life data is as follows:

Cycle life (10% DOD):> 1000 times

Cycle life (100% DOD):> 200 times

DOD is the depth of discharge in which the English abbreviation. Can be seen from the table may be the depth of charge and discharge times, 10% DOD cycle life than when the 100% DOD for much longer. Of course, if the actual charge equivalent to the relative total capacity: 10% * 1000 = 100,100% * 200 = 200, the latter a full charge and discharge, or better than some, but in front of friends do say that some of the amendments: Under normal case, you should have a reserve 312-0386 battery power is left in accordance with the principle of charging run out of charge again, but if your battery in your first two days can not be expected to persist throughout the day, when they should start on time charge, of course, if you are willing to back the charger to the office again a different matter.

Run out of battery power and then filling the remainder of the principle is not want you to go to the extreme. And long, like charging a widespread view that "as far as possible the battery power runs out." This is really just practice on nickel batteries, The purpose is to avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone battery warning appears, still do not charge to continue to use the example has been used in automatic shutdown. The results in this case, cell phone charging and starting later in the no response, had to give customer Latitude D620 service overhaul. In fact, this is because of the battery caused by excessive electrical discharges in low voltage, so that does not have the normal charge and the boot and conditions.

Personal proposed mobile phone battery at full power to maintain the state of Georgia, when the power began to charge when dissatisfied ,2-3 hours or less is appropriate.

By lithium-ion battery electrolyte can be divided into sub-liquid lithium-ion battery and polymer lithium-ion batteries, polymer lithium-ion battery electrolyte is a gel will not flow, so there is no leakage problems, more secure.

Rechargeable lithium-ion batteries should not be too full of not use to no electricity. Did not run out of RC107 battery charging will not damage the battery
