Can the ordinary battery be charged?

It depends on the situation.

Traditionally, ordinary batteries usually refer to No. 5 and No. 7 ordinary zinc-manganese batteries, also known as dry batteries and carbon batteries. These batteries are disposable and cannot be charged.

However, most of the batteries we often come into contact with in our daily life are lithium-ion batteries. Therefore, when ordinary batteries are interpreted as lithium-ion batteries, most ordinary batteries can be charged.

If you want to charge your battery, you'd better distinguish whether it is a rechargeable battery or not.

Lithium batteries are divided into two categories: non-rechargeable and rechargeable.

Non-rechargeable batteries are called disposable batteries, which can only convert chemical energy into electrical energy at one time, and cannot restore electrical energy to chemical energy. Such batteries typically contain lithium in a metallic state.

A rechargeable battery is called a secondary battery (also called a storage battery). Lithium-ion batteries do not contain lithium in the metallic state and are rechargeable. It can convert electrical energy into chemical energy and store it. When in use, it converts chemical energy into electrical energy. It is invertible, such as the common lithium-ion mobile phone batteries on the market.

How to identify whether it is a lithium-ion battery?

Most Lithium-ion batteries will have some form of printing on them which contains either the words “lithium-ion”, “Li-ion”, “Li-po”, “Lithium-polymer”, or some other variation of “Li” to denote the chemistry. If the battery is rechargeable and has “Li” or “Lithium” printed on it, you can safely assume that it is a lithium-ion battery.

How to charge Li-ion battery?

The new lithium-ion battery can be unplugged and used when it is fully charged. Generally, it will be fully charged in 2-4 hours. Do not charge it for more than 8 hours to 12 hours, or it will harm your battery.

Lithium-ion battery activation does not require special methods. The battery has been activated before leaving the factory, just use your battery normally.

When the mobile phone battery is too low prompt, you should try to start charging in time. Lithium-ion batteries are the most vulnerable to damage in the event of over-discharge.

Lithium-ion batteries should also avoid overheating. When charging, if your heat dissipation is poor and it gets hot when charging, it is best to take off the case while charging. It is not recommended to use the mobile phone while charging. Even if you want to play while charging, it should be safer when the battery is half (that is, about 50%).

Some misunderstandings about the use of lithium-ion batteries.

1.A newly purchased lithium-ion battery needs to be fully charged and discharged three times before it can be fully activated, and the first charge should last for more than ten hours.

In fact, lithium-ion batteries have no memory effect, and generally can be fully charged in 2-3 hours, which is enough. If the first three charges and discharges of a new battery can really reach 12 hours or more, it will cause great damage to the battery, which may cause the battery to swell or even burn. Fortunately, both the mobile phone and the charger have protection circuits.

When the battery is charged to 100%, it will automatically cut off the power, and it will not continue to charge when it is plugged into the charger. However, it is better to unplug the charger at this time, in case the battery is overcharged in the charger protection circuit. That will cause serious damage to the battery material, affecting the capacity and life of the battery.

2.The laptop should be unplugged when fully charged.

Most notebooks also use lithium-ion batteries, so do you have to unplug the battery when the computer is fully charged?

If you use a laptop for work, it is best to keep it plugged in to reduce the loss of overcharging and discharging the battery. Because during the charging process, if the battery is full, the laptop will be powered directly by the power supply, not the battery. But before going to bed at night or when not in use for a period of time, you should unplug the power supply to let the battery get a certain rest, and also to prevent accidents.
