Acer 4750g how to set the battery to charge to 45 before charging, now the default is 95.

In fact, you don't need to adjust it, I know you're worried about the impact of multiple charges on battery performance, in fact, don't worry, I found you some information on the encyclopedia, you can take a look. I believe that the vast majority of consumers have heard that the life of lithium batteries is "500 times", 500 times of charging and discharging, more than this number of times, the battery will be "at the end of life", many friends in order to be able to extend the life of the battery, every time the battery is completely exhausted before charging, so that the life of the battery really has a prolonging effect? The answer is no.

The life of a lithium battery is "500 times", which refers not to the number of charges, but to a cycle of charge and discharge. A charging cycle means that all the battery power is used from full to empty, and then from empty to full, which is not the same as a single charge. For example, a lithium battery uses only half of its power on the first day, and then fully charges it.

If it is still the case the next day, that is, it will be charged half of it, and a total of two charges will be charged, which can only be counted as one charging cycle, not two. As a result, it can often take several recharges to complete a cycle. With each completed charge cycle, the battery capacity decreases a little.

However, this reduction in power is very small, and high-quality batteries will still retain 80% of their original capacity after multiple cycles, and many lithium-powered products will still be used as usual after two or three years. Of course, lithium batteries still need to be replaced after the end of their life. The so-called 500 times means that the manufacturer has achieved about 625 rechargeable times at a constant discharge depth (such as 80%), reaching 500 charging cycles.

80%*625=500) (ignoring factors such as the reduction of lithium battery capacity) And due to the various effects of actual life, especially the depth of discharge when charging is not constant, so"500 charge cycles"Serves as a reference to battery life only.

Mine is associative, you can tune it, haha, you don't know, I can't help you, God.

Maomao, you're a fool, aren't you...

It should be battery protection, or the battery will be charged frequently, and the number of charges will be greatly reduced, but you can also turn it off, generally the original system or software will have battery protection.

Normal. Today's laptop batteries generally have circuit protection devices, which means that the battery has reached 95%-99% saturation voltage when you start using the power supply. At this point, your laptop detects that the voltage difference is very small, so it will reduce the charging current to prevent the charging current or voltage from being too large and causing damage to the battery.

You need to set it in the power manager, you may have the default upper limit of about 95%, just change it.

The general notebook computer can be charged to 100% under normal circumstances, and now some laptops are equipped with power management, according to the charging and discharging characteristics of the lithium battery, maintaining 80-95% of the power after charging can make the lithium battery maintain a long life, according to this, many power management software, set the charging mode that can be customized by the user.

You can view the relevant settings in the power management properties.

Acer laptops have good ePower Management battery management software, which is great for extending battery life.

You use a professional software, conduct a discharge test, and recover.

This does not affect. Lithium batteries have little to no memory effect. So it doesn't matter how much you put it in.

Secondly, there is no need to worry about the number of charge and discharge. For example, if you charge at 50 percent this time, you will charge at 50 percent next time, and add up to 1 charge. So there's no need to worry about anything else.

No, it can't be set up in the computer at all. This is probably possible in the BIOS. Everyone else is talking nonsense. If it is set in the system settings, why does the computer still charge at 95% when the computer is turned off?

Acer go to the control panel and have the power settings inside to check it out.

There's no way around this, you have to pull out the battery, and that's how I am.

Click on Control Center in the Start menu, click on the battery option in Power Management, and change it to your desired state in the Advanced Settings after Activating the battery care function.

Generally, it is okay to keep the power at 5% or 10%, but do not use it all up and recharge, so that the battery is easy to die. If there is an external power supply, it is best to remove the battery, one can reduce the number of battery charging and discharging, and the other can reduce the impact of radiation, and a large part of the computer radiation comes from the battery. However, it is best to install the battery and discharge it every few weeks to keep the battery alive.

Many of my friends' batteries can only be used for ten minutes because they are not good.

My Lenovo thinkpade420 can be set in the control panel - power manager - battery maintenance, the value can be set arbitrarily, it is recommended to start charging at 5% and end charging at 100%. I usually plug in the power supply, but the battery is not unplugged, I am afraid that a sudden power failure such as a power outage, will hurt the book, so the setting should relatively reduce the number of charging and discharging, and the battery will be less damaged.

It's best to remove it when not in use, otherwise the more you use the battery, the more you can't store it.

It's still the default of the computer.

The lithium battery is activated at the factory, and the 12-hour ultra-long charging is completely unnecessary, 8 hours is enough.

A normal full charge takes just over 2 hours. In the future, it is necessary to disassemble the battery and put it directly on the book to prevent the damage to the book due to sudden power failure, and the battery is not so fragile. Don't be too particular about it in the future.

The first charge is the same as a mobile phone, it takes 12 hours to be fully charged, and the last two times are 12 hours.

Regardless of whether the lights are on or not, some machines have fast charging technology. Generally, the battery needs to be fully charged before the first three uses. Not in the future.

You can see if your notebook is in the following situations:

1. When the NB battery is lower than 95%, the charging function will be activated, and the battery will stop charging when it is charged to 100%.

2. However, when the NB battery level drops from 100% to between 99-95%, it will not be charged when the power adapter is connected, and it will not continue to charge until the battery level is lower than 95% and the power adapter is connected.

3. If the NB battery is charged to 97% when the battery level is 94%, unplug the power adapter and connect it to continue charging to 100%.
