The No. 5 battery is the earliest battery that many children contact. I remember that the battery pack used in the electrical experiment in primary school was the No. 5 battery. Although many digital products, such as mobile phones, have built-in batteries, the home's various remote controls, alarm clocks, wireless mice, etc. still need No. 5 batteries. No matter in the past or now, No. 5 battery is closely related to our life. Early on, because I thought it was too wasteful to use ordinary batteries only once, I began to use rechargeable No.5 batteries. Recently, a new type of No. 5 battery was discovered, which is the Shuerbo USB rechargeable lithium battery.

Shuerbo No. 5 battery is a lithium battery with USB fast charging technology, 1200mA, 1.5V constant voltage and current, one hour fast charging, and no memory effect. The outer package is mainly orange, giving people a feeling of full energy. It is huge and rich - technology lights up life.

According to the main parameters and indicators on the paper cover, the Shuerbo battery can be fully charged in 1 to 2 hours under the 5V/500mA charging environment; The output voltage is about 1.5V, the current is 1A, and the battery capacity is 1.5V/1200mA, which can meet the general use scenarios; The service life of the battery is more than 5 years, and it can be recycled for 2000 times. It has the same size of 14.2 * 50mm as the ordinary No. 5 battery, but its weight is only 14g. Open the paper wrapped package above, and there is a frosted plastic box inside, in which the Shuoerbo battery is installed. This battery storage box can be recycled, which is more careful than the packaging of ordinary batteries.

Open the plastic storage box, and four Shuo Erbo No. 5 batteries are neatly packed in the box. The main color of the batteries is also full of energy orange plus technical silver, which is very beautiful. Some parameters and identifications are marked on the battery for convenience.

This is the main body of the battery. Energy orange, technical silver and high-end black form the three main colors of the battery appearance. There are a lot of orange on the left side of the four batteries below the battery. It seems that the battery packaging was a bit careless.

Compared with ordinary batteries, the size of Shuo Erbo is the same, but its weight is much lighter than those of the two models on the right. The GP Super Super 20g, Nanfu Energy Shaped Ring 24g, and Shuo Erbo are only 14g. The lighter the size and weight of the same battery, the lighter it will be when used, especially in a wireless mouse.

The orange battery cap on the Shorebo battery can be opened. After opening, a rubber band connects the battery cap and the battery body to prevent the battery cap from being accidentally lost. However, the service life of this rubber band is unknown, but it can be assured that the absence of this rubber band does not affect the normal use of the Shorebo battery according to observation, because in addition to the rubber band, In fact, the orange battery cap has a metal connected to the battery body to transmit current. The connection of this metal part to the battery body is the key to normal use.

Referring to the pictures on the official website of Shuerbo, this is the structural section diagram of Shuerbo battery. It can be seen that lithium battery accounts for the majority, and the core part is in the USB socket. The USB only power management chip provides the entire battery with overshoot protection, short circuit protection, leakage protection, over-voltage protection, over temperature protection, and over-current protection, so as to enhance the efficiency of battery use and make the battery safer and longer.

There is a standard USB interface on the top of the Shorebo battery, which is used to charge and input power. In this way, it is not necessary to use a special charger like the ordinary charging No.5 battery. It is very convenient to use the USB socket on the home computer, the charger for mobile phones and tablets, and the mobile power supply to charge at any time.

In this way, there is also a ring under the Shuo Erbo battery, and the orange ring at the bottom echoes with the battery cap.

When Shuo Erbo battery is plugged into the charger, a circle of red lights lights up unexpectedly. No wonder that Shuo Erbo battery's wrapping paper is printed with "Technology lights up life", which should echo a little. This kind of light display of charging status is also very intuitive and beautiful.

In half an hour or so, the light of one battery turns green again, which is full. The battery is almost not hot during charging, which makes people feel very safe.

After another half hour or so, the second battery was also full. Maybe the two batteries had different reserved power before they came out, so the charging time was different.

Actually, it can be used normally in my wireless mouse. Because the Shuo Erbo battery is much lighter, the wireless mouse also saves much effort.

To sum up, Shuerbo's battery: 1. It is convenient to charge without special charging equipment; 2. Fast charging speed, saving time; 3. Light weight, easy to use; 4. Long battery life and many cycles; 5. Constant voltage and current, no change in voltage and current during use; 6. Intelligent security chip, safe and durable. Therefore, this battery is very safe and convenient to use, and the overall cost is not high. It is planned to replace all the batteries at home with Shuo Erbo USB fast charging lithium batteries in the future.
