Batteries are inseparable from our current life. It can be said that most of the electronic products needed in life need batteries. Small as mobile phones and watches, large as cars, yachts, and even satellites and space stations in outer space need battery equipment. There are many advantages of battery, so let's not say more here. Its biggest disadvantage is not the power problem, but the environmental pollution problem. So the society is calling for the use of rechargeable batteries to reduce environmental pollution.

There are many types of batteries, including alkaline batteries, alkaline zinc manganese batteries, cadmium nickel batteries, nickel hydrogen batteries, etc. according to the type of electrolyte; According to the working nature and storage mode, it includes: primary batteries, i.e. batteries that cannot be recharged, such as zinc manganese dry batteries, lithium primary batteries, etc; Secondary battery, namely charging cell, such as nickel hydrogen battery, lithium ion battery, cadmium nickel battery, fuel cell, etc; The third category: according to the positive and negative materials used in batteries, it includes: zinc series batteries, such as zinc manganese batteries, zinc silver batteries, etc; Nickel series batteries, such as cadmium nickel batteries, nickel hydrogen batteries, etc.; lead series batteries, such as lead-acid batteries, etc; Lithium ion battery, lithium manganese battery; Manganese dioxide series battery, such as zinc manganese dioxide battery, alkaline manganese dioxide battery, etc.

Recently, a Shuo Erbo USB rechargeable lithium battery came into my view. The advantage of lithium battery is that it has no memory effect and can be charged at any time. It uses USB interface for charging, which means that the battery can be charged at any time in any environment. It is no longer necessary to charge the battery with home power like the previous rechargeable battery.

This Shuerbo USB rechargeable lithium battery is commonly referred to as No. 5 universal battery, and each package contains four batteries. On the outer package, the product features were briefly introduced, including 1.5V constant pressure, one hour fast charging, no memory effect, etc.

The back of the package introduces the basic information of the product. Of course, the most important thing is the battery capacity. Although the capacity is slightly lower than some nickel metal hydride batteries, it should also meet the needs of use because of its fast charging.

Remove the outer package. Inside is a plastic box. The lid of the box is very tight, and it can only be opened with great force. If it is a girl, it may be difficult to open it. It is estimated that the purpose of this design is to make it easy to carry and avoid being affected by moisture or extrusion.

The color matching of Shuerbo USB rechargeable lithium battery is quite different. The bright orange upper cover and the silver body are easy to attract people's attention.

A layer of transparent plastic is sandwiched between the upper cover and the body, which can display different colors when charging.

The upper cover and the body are connected by a section of rubber band. The purpose of this setting is that the rubber band has a certain elasticity, which can meet the requirements of USB charging ports of different shapes. However, the author is worried that the rubber band is not wear-resistant enough after a long time of use, so everyone should pay special attention when using it.

The metal sheet protruding from the upper cover should not be considered as decoration, which is a very important design. It is the positive connection point of Shuerbo USB rechargeable lithium battery. If it is damaged here, the battery will be basically discarded.

Each battery has a fixed and unique factory code at the bottom, and problems can be reversed.

The author uses the ANKER fast charging system power supply to charge with the Q3 and Q1 interfaces respectively. The first charging time is basically the same, which is about 40 minutes. Due to the different residual power, the charging time is naturally different. It can be seen from the photo that the five charging ports can only charge three batteries, so you should also consider the location of the charging ports when choosing a charger.

The power light is red when charging, and the green light is on after charging. Fast charging can make up for the low battery. Unless users with special needs are picky, most users are suitable for this battery.

The voltage measuring instrument is used for special test. The current is obviously large when the battery is charged. The longer the charging time is, the smaller the current will be. The current will be zero after the battery is fully charged, which indicates that it is equipped with an intelligent chip to ensure charging safety.

summary

This Shuerbo USB rechargeable lithium battery can be charged quickly in one hour, which makes users feel safe to use, meets the needs of most users, and the charging protection function is far more than the ordinary rechargeable batteries on the market. The most important is the lithium polymer battery cell, which is environmentally friendly and durable, can be recharged more than 1000 times, and has the characteristics of no memory effect, which greatly improves the life and use efficiency of the battery.
