How to make lithium batteries live longer

How to make notebook, mobile phone lithium battery life to reach the longest?

"The more lithium batteries are discharged, the greater the battery loss will be," says Akron,

Tom Hartley, an electrical engineering professor who helped NASA study extended battery life, said: "The fuller the battery is charged, the greater the loss of the battery.

Lithium batteries are best placed in the middle of the charge, so that the battery life is the longest. "

First of all, the low power state of Gaohe has the most adverse effect on the life of lithium batteries.

The number of charge and discharge cycles is secondary. In fact, most of them sell electrical appliances or batteries

The number of rechargeable times identified is based on the 80 % discharge test.

Experiments have shown that for some laptop lithium batteries, the battery voltage often exceeds

The standard voltage is 0.1 volts, which is increased from 4.1 volts to 4.2 volts, and the battery life is halved.

If you increase 0.1 volts, the life span will be reduced to one-third of the original; Long-term low or no power

The state of the battery will cause the internal resistance to the movement of electrons to increase, resulting in the battery

The capacity is smaller. NASA's got batteries running on its Hubble space telescope.

Set the amount at 10 % of the total capacity to ensure that the battery can be recharged 100,000 times.

You don't have to update it. Battery consumption on the Hubble Space Telescope is set at 100 % of total capacity.

10, battery charge and discharge cycle up to 100,000 times

Second, temperature also has a greater impact on the life of lithium batteries(mobile phones and other small electronic devices)

For this point to be negligible). An environment below freezing point could turn lithium batteries on in electronics

The instant it burns, the overheating environment will reduce the battery capacity. So, if the pen

Electricity is used for long-term external power supply and does not remove the battery, the battery has long been in the notebook row

Of the high heat, the main thing is that the battery is in a long-term state of 100 % of the electricity and will soon be scrapped(including my own laptop battery).

From the above, we can summarize the following points to ensure the capacity and life of lithium batteries attention

Matters:

Lithium batteries do not need to be charged to 100 percent of the electricity, let alone used up.

Try to keep the battery power near half full when circumstances permit.

The smaller the charge and discharge, the better;

The factory design of GM's Chevy Volt electric car is to force the battery power to be maintained at 20

% to 80 %, and Apple's built-in battery may also use this method(including

Other laptop and electronic products increase the number of charterable discharge cycles of the battery.

Do not use lithium batteries(especially notebook lithium batteries) for long-term external power supply in equipment

On the job. Even if your laptop has good heat dissipation, the long-term 100 percent charge will wait

Murder of lithium batteries.

1. If you use an external power supply to power your laptop for a long time, or if the battery has already been charged

More than 80 %, remove your laptop battery immediately, do not need to fill the battery for normal charging,

Charge to about 80 %; Adjust the power options of the operating system and turn the electricity alarm to 20

Above %, the battery power should not be less than 20 % in normal times, and it should be required before it drops to 20 %.

Charging;

2. Small electronic devices such as mobile phones, when charged, should immediately disconnect the power cord(including charging)

Functional USB interface), which will continue to damage the battery; Keep charging. Just remember.

Fill, but do not have to fill the battery;

3. Whether it is a notebook or a mobile phone, do not let the battery run out;

4. If you want to travel, fill up the batteries, but remember that conditions allow

Charge electrical appliances at any time, for battery life, must not wait for the battery to dry;

Nowadays, people have a lot of electronic equipment, and a large part of them use lithium batteries to ensure that

Battery life is very practical. After all, the battery is scrapped and recycled, otherwise it will be on the ring.

The environment caused serious pollution.
