Dangers of waste batteries
A button battery can pollute 0.6 million liters of water, which is equal to the amount of water consumed by a person throughout his life. A battery rotten in the ground can make 1 m² of the land lose the use value, so it is not too much to describe a waste battery as a "pollution

Check for software problems
In general, many computer brands such as Dell, Lenovo, Sony, etc., will be equipped with their own notebook power management software. If some kind of "battery protection mode" is enabled, the power management software can prolong battery life by detecting that the user uses AC power to prohibit battery charge and discharge.
So, if y
Android Battery Management System1. Overview
With the rapid development of mobile smart devices, the battery endurance has greatly induced the purchase choices of consumers, the rationality of the Power Management in the android system directly affects the battery endurance, it is mainly used to monitor the battery sta
Use rechargeable batteries
Using rechargeable batteries is one of the advantages of laptops relative to desktops, which can be used in a wide range of environments with laptops. The first battery to be released was Ni-CD battery (NiCd), but this kind of battery has "the memory effect", each charge must discharge before, the use is very inconvenient, soon was rep
Do you often encounter the following situations when you have a love book? Meeting presentation ppt When the notebook is still 30%, but suddenly encounter no electricity embarrassment? The key moment in the game suddenly encounter battery power? Notebook just bought back less than a year time battery but frequent strike false power? Important issues such as business and office notebook but the time is getti
Maintenance Method:
Maintenance method One, minimize the number of batteries used
Battery charge and discharge times directly related to life, each charge and put a one-time electricity, the battery will consume a small part of life, so it is recommended when there is an external power supply as far as possible plug in external power, do not use battery power,
Generally divided into: 1, 2, 3, 5, 7, of which 5 and 7 are particularly commonly used, the so-called AA battery is 5, and AAA battery is 7! Both AA and AAA indicate the battery model.
For example:
AA is what we call battery 5. The general size is 14mm in diameter and the height is 49mm;
AAA is what we call
Q: Does the cell phone charge have any effect on the battery?
A: The answer is yes, while fast charging can improve the efficiency of cell phone charging, but also has an impact on battery life. As for why, we will introduce the following details here, with the answer attached here first.
Q: Is the cell phone charged well or slow?
A: If you look at it from the experience point

"The more the lithium-ion battery discharges, the greater the loss of the battery," said Tom Hartley, a professor of electronics engineering at NASA, which Akron the space agency's research to extend battery life, saying, "The more you charge the battery, the more the battery
This article illustrates the Android implementation of a dynamic display of battery status, power and charge, and is a very common feature in the development of Android applications. Share for everyone to use for reference. The specific methods are as follows:
Use the battery on the Android system to listen and the battery picture of the system is as follows;
Computer now has become a daily necessities of life, then how much do you know about computers? The following small series for you to organize some common computer hardware knowledge, quickly to learn!
Computer hardware, including all the physical parts of a computer, to differentiate between the data it contains or executes and the software that provides instructions for the hardware to complete the task. Computer hardware mainly includes: chassis, motherboard, bus, power, hard disk, storage c
The ion battery protection circuit includes overcharge protection, overcurrent/short-circuit protection and over discharge protection, requiring overcharge protection, high precision, low power consumption, high voltage and 0 volt charging characteristics. The principle, new function and characteristic requirements of these three kinds of protection circuits are introduced in detail in this paper.
Lithium battery
In our laptops, there is one thing that is particularly noteworthy, and this is the battery. With it, we will not in the unexpected power outages, hard code out of the text will not be lost. But what's slightly different with other hardware is that you need to always take care of your batteries. For example, the battery should be properly cycled charge and discharge operation, to minimize some depth dischar
First, the new notebook does not need to activate, also do not need to charge the first three times 12 hours deep fill deep, this is mainly lithium battery principles and characteristics of the decision. The battery design has the power to protect, it is impossible to completely run out of electricity, of course, can not overcharge.
Second, the life of the laptop
※ Standard Maintenance ※
The maintenance of lithium batteries is very important to keep the batteries in the current state of the electronic moment. Cheenerio advises you not to use your laptop power all the time. Ideally, use your laptop battery when you go out and go back to the office and use the power to recharge it. This will keep the battery current flowing. On the other hand, if you use a desktop co

Laptops are now particularly popular, both outdoors and indoors, especially outdoors, where laptops are powered by batteries. For a long time, we will find that the battery's endurance is not as long as the beginning, before it can be used for 3 hours, now only 2.5 hours of endurance. What's going on?
Shorter endurance, not a problem with the battery itself.
For batteries that use less than 1 years, the duration of the
