How to judge the quality of 18650 lithium battery

As follows:

1. False capacity:

Currently, China's 18650 battery technology has a capacity of 2200, and many sellers falsely state that low-capacity batteries have a capacity of 3000 or 3200. attract customers consumers, etc. to deceive consumers and obtain more benefits.

2. Reconditioned Batteries:

Reconditioned batteries come from disassembled foreign batteries, obtained through some illegal channels, and then reconditioned and marked with fake capacity. These batteries are very dangerous for consumers. This involves carrying a timed explosive with you, and consumers are asked to keep their eyes peeled for consumption.

3. Copycat Battery:

I think everyone knows the word copycat. Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material. a non-aqueous electrolyte. In thebatteries in solution, the chemical properties of lithium metal are very active, making the processing, storage and use of lithium metal very demanding on the environment. Manufacturers of counterfeit batteries may completely ignore these requirements, which can lead to danger at any time.

Consumers should pay attention to the above conditions when purchasing LED flashlights. Buying from a regular manufacturer of powerful flashlights is guaranteed.

How many years does a cell phone battery last? Before answering the question, let’s understand the evolution of cell phone batteries.

In the age of feature phones, it is not uncommon for mobile phones to have a full battery life of 2 to 3 days or even more. However, in the era of large-screen smartphones, battery life is reduced. cell phones suddenly fell to one day, evennot a day.

Cell phone batteries were originally made of nickel-chromium. ? In addition to the short battery life and long charging time, the memory effect of nickel-chromium batteries is also very serious, making it impossible for users to recharge at any time. Various batteries followed, and eventually lithium batteries appeared. In 1992, the lithium-ion battery that Sony had been developing for many years finally entered commercial use.

Lithium batteries still have very good autonomy in the era of smartphones. However, once the smartphone is turned on, the battery life is increasingly insufficient due to the rapid development of large screens, powerful processors, and memory. and other electronic components.

Composition of the cell phone battery: compared to cell phones, the most important elements regarding bLithium-ion ateries are actually two points: good safety performance and long service life. The lifespan of lithium-ion batteries is generally 2 to 3 years. Generally, it can be used more than 500 times, or even more than 1,000 times.

How long can a cell phone battery last?

How to extend battery life of mobile phones: Try to charge your mobile phone as much as possible at ordinary times, and charge it as soon as possible when used at less than 10 % ; avoid environments with excessive temperatures. If you want to extend battery life better, besides fast charging, the most direct way is to use a power bank. There are many power banks on the market today. For example, the fast charging secretary power bank is very suitable for users. Secretary Bao Supports traditional fast charging protocols such as PD, which can fully charge your phone faster. At the same time, the built-in cord design makes it easier to go out.
