Lithium battery cannot be placed for a long time without application

Since buying it when buying a camera two lithium batteries a battery has been not willing to use, when to charge out today found that the charger is not bright lights flash or two, no way to charge, how do ah, look at it later on the Internet search I found that my battery has been scrapped, I feel bad, ignorant. . . . . .

Brothers, then there are hands inside lithium battery, and remember to charge ah, or over-discharge, they never charge does not go, the equivalent scrapped, and that distressed ah. . . .

It turned out that we have been wrong! Here are lithium" batteries maintenance method.

All along, how do you charge the iPhone, iPod touch, and iPad? Is it better to wait until the battery is running out and recharging? Do you want to charge for 12 hours on the first charge? Does charging often reduce battery life? My mobile phone is connected to the computer every day. Will it break early?

In order to solve the above problems, I specially sort out this article today and hope to help everyone:

Conclusion:

1. The device using lithium battery, the first use does not need to charge for 12 hours, this is not necessary!

2. Charge at any time, it has no effect on your device, because the lithium battery is not afraid of you charging, I am afraid there is no electricity!

3. The battery is exhausted, please charge it as soon as possible. If the time is too long, the battery will not be able to sleep!

Types of batteries:

First of all, we must first understand that there are many different types of batteries, and the iPhone, iPod touch, and iPad use "Li-ion lithium-ion rechargeable batteries". Generally, we buy them at convenience stores. Primary battery], common are alkaline batteries, manganese dry batteries, silver oxide batteries, mercury batteries, etc. These batteries can only be used once, after the power is used up, it must be discarded and recycled!

The other is [secondary battery], which is called a rechargeable battery. Common types are nickel-cadmium batteries, lead-acid batteries, nickel-hydrogen batteries, lithium-ion batteries, fuel cells, and so on. But just look at it, you don't have to take notes, because the real battery classification is more than that!

In this article, I will use the "Li-ion lithium-ion rechargeable battery" for iPhone, iPodtouch, and iPad to share the usage:

Lithium battery can only be charged and discharged 500 times? It’s right, it’s wrong, it’s wrong!

In some international research data, the number of charge and discharge is really limited, which is correct! But this must be structured in the case of running out of power, that is, if you charge the battery (4.2 volts) and then continue to use it (3.6 to 3.7 volts), if the power is getting lower (3V~2.5V), then A weak current warning will start, and if it is lower than 2.5V, the battery will be depleted and automatically turned off. This action is called deep discharge (from 2.5 volts to 4.2 volts).

According to the experimental data according to foreign countries, the number of deep discharges of excellent lithium batteries can reach more than 500 times. In other words, although the action of deep charge and discharge (full, depletion) is not good for lithium batteries, such a The number of actions and life is also up to 500 times or more, but it depends on the design and quality of the battery (if you save the brand, your battery still has its own reasons), but it is certain that... The more times you run out of time, the time for your battery to return to the west will come early!

However, according to the characteristics of the lithium battery, if the voltage inside the battery is low to some extent, then the lithium battery will be self-closing, and the real-time is not broken, because the voltage is already below a certain limit, and the battery can not afford to sleep. The state of death (this is now called a false fault)!

So you will find out, if your mobile phone battery or digital camera battery has not been used for a long time, how can the battery not be charged? Or is the lifespan getting shorter and shorter? In fact, this is because the battery is exhausted, causing the voltage to be too low to allow the lithium battery to start, which in turn causes the battery to fail early (because the voltage is lower than the voltage, the battery can no longer start the charging process)!

This kind of situation most often occurs on the battery of a digital camera. Many people will buy more batteries for digital cameras, but sometimes these batteries are not used often, plus the usual neglect of charging, so one does not pay attention, These batteries are discharged in such a way that when the battery is below a certain voltage, the battery is scrapped (so nothing to remember to take the battery out and charge).

Good batteries will have a "charge management IC" to limit the charging and discharging voltages to ensure that the battery does not exceed the safe voltage (overcharge) and the battery will explode. It will also be detected by the IC to avoid less than 2.5 volts. Keep the battery from running out due to exhaustion. But if you have a battery that is almost out of power, and you are not charging quickly, then the battery will still be eaten up slowly by the built-in management IC. When the voltage is lower than 2.5V, your battery will be scrapped.. ...

If the lithium battery is not charged for a long time, it will be broken.

Excessive charging. This problem is solved in many devices when it is fully charged. Therefore, you don't have to worry about this problem! But another problem is actually that everyone should pay more attention to it, that is... Don't put the battery completely dead!

I often hear people say that it is recommended that "it is best to run out of battery power, it is best to use it after charging off," but this is completely wrong in the world of lithium batteries! When the iPhone has a 20% power warning, it is ready to be charged. If the lithium battery is over-discharged, it may cause the battery voltage to be too low, causing the battery to sleep in a hibernation state, and the battery will be scrapped early. !

When the new battery is used for the first time, it does not need to be charged for 12 hours. The

new battery needs to be charged for more than 12 hours. In fact, it is the continuation of previous nickel batteries, such as nickel-cadmium (Ni-Cd) and nickel-hydrogen (Ni-MH) batteries. Saying, but technology is improving, after the lithium battery, in fact, there is no need to do this action! Even excessive charging and discharging are harmful to lithium batteries.

Many products (mobile phones, digital cameras,special) will require you to fully charge for more than 12 hours when you use it for the first time. In fact, it is for "safety" because these products are shipped from the factory until sales. To the user's hand, this process may take several months, and these batteries may be lost due to the slow loss during this time, so in the original description, you are usually advised to connect first. Charger, and to charge more than 12 hours, in fact, is to avoid playing when you get the device, then if you play the battery below 2.5V, then the battery is bad! Therefore, the original factory will ask you to charge for 12 hours, in fact, in order to avoid the user's "handwork" that the battery is exhausted.

Most of the chargers or devices (mobile phones, digital cameras, notebook computers, etc.) will automatically stop charging after the battery is fully charged, and the protective device that is turned off under weak current to avoid damage to the battery. But there are some cheap batteries or chargers that "may" not do this (cost), so be sure to pay attention when using it. If the battery is full, take it off and don't have to keep it on the charger. It doesn't make sense. And if the battery is dead, just take it down and don't continue to use it, so as not to cause the battery to run out, so the battery will hang!

If you want to charge it, try to keep it in a state of electricity. This is right.

So, in general, don't let your battery run out of power! This is the best protection. Plug in the charging cable and transmission cable at any time. It has no effect on the battery. The characteristics of the lithium battery itself determine that it has almost no memory effect, so even if you have 80% of the power, you can boldly charge it. After the battery is fully charged, it will automatically stop charging, so your battery will not overcharge and will have no effect on the battery!

In other words, the lithium battery is not afraid to charge at any time, but is afraid of no electricity! When the battery is low, you should charge it as soon as possible or replace the battery. Don't let it run out completely (for example, the battery of a digital camera, don't try to shoot it completely, it hurts).

If the lithium battery is not powered, and it will not be used for a long time or charged, it will cause the lithium battery to fail because it is too low. It is often used when the lithium battery is exhausted. Its life expectancy is at least less than half, so don't be careless.
