The battery is a small object, but the pollution is also extremely serious. Before entering the theme, let's talk about science popularization (Baidu Encyclopedia):

In recent two years, the impact of waste batteries on the environment has become one of the hot topics in domestic media. Batteries pollute the environment seriously. One battery can pollute 60000 cubic meters of water. Some even said that waste batteries could cause hazards such as Minamata disease in Japan with the disposal of domestic waste, and that a section of No. 5 waste battery could make one square of land waste, etc. These reports have caused great repercussions in the society, and many environmentalists and groups have carried out or participated in activities to recycle waste batteries.

A button battery discarded in nature can pollute 600000 liters of water, equivalent to a person's lifetime water consumption. China consumes 7 billion such batteries every year. It is understood that 96% of the batteries produced in China are zinc manganese batteries and alkaline manganese batteries, whose main components are heavy metals such as manganese, mercury and zinc. No matter in the atmosphere or deep underground, the heavy metal components of waste batteries will overflow with the leachate, causing pollution of groundwater and soil, and will seriously endanger human health over time. Mercury, cadmium, zinc, lead and chromium were identified as hazardous wastes in the National Catalogue of Hazardous Wastes in 1998. The calculation result of 600000 liters of water pollution is based on the assumption that all the heavy metals in the button battery are dissolved in water and evenly distributed in the water. But in fact, it is very difficult for heavy metals to dissolve in water, let alone evenly distributed in the water. The actual possible pollution is far less than the maximum value calculated in theory.

Next, we will introduce a pollution-free and sustainable Shuerbo USB rechargeable lithium battery.

First of all, I got four battery packs of Shuoerbo 5 USB battery this time. What I saw was the battery case and the striking words of Lei Feng's computer trial.

The front side of the battery package introduces the brand, slogan and main functions of the battery: 1.5V constant voltage battery, one hour fast charge, no memory effect, and No. 5 USB fast charge battery.

Detailed parameters of this battery are marked on the back of the package, rated input voltage/charging current: 4V/500mA, external to internal battery charging time: 1-2hr Output no-load voltage: 1.5V ± 0.2V, rated output current: 1A, battery capacity: 1.5V/1200mA ± 10%. Overall service life: ≥ 5yr.   Overall dimension: 14.2X50mm, overall weight: 14g.

The front design of the battery is very simple and generous without any redundant design, which proves the high-level design of this battery again.

The three-dimensional feeling of the battery is that the bottom is very flat, and there is no convex design.

Each battery is designed with nylon rubber band to hold the battery positive pole cap, so as not to lose the cap. The design is very careful.

The USB side on the top of the battery is designed as a universal interface, and the nylon rubber band connection is also very reasonable without any burrs.

From the perspective of appearance and size, the shape design of Shuoerbo 5 # USB fast charging battery is exquisite and compact, which is no different from the ordinary 5 # battery. There are one positive and one negative electrode at the top and bottom. But when we look closely, we find that the positive and negative electrodes can be pushed away. It can be seen that it is a standard USB interface, through which we can charge this USB charging battery.

The content of each cell of Shuo Erbo No. 5 battery is 1200 MAH. If it is not an empty label, the capacity is very good. Compared with the content of 600~700 MAH of ordinary No. 5 battery, it is about twice the level. As the battery cell of the Shorebo battery is lithium battery, its weight is much lighter than that of the ordinary No. 5 battery.

The battery USB port is the positive pole above and the negative pole below, which is simple and easy to distinguish.

The Shuo Erbo 5 USB fast charging battery can be plugged into the USB interface of the computer. The mobile phone charging head, USB socket, and mobile power supply can all charge it. It does not need a charging stand, which is convenient and quick. It has overcome the limitation that charging batteries must be equipped with a special charger.

The charging speed of the notebook USB is basically consistent with the described charging time.

Summary, In the test, I felt that the Shuo Erbo USB fast charging lithium battery is more durable than the ordinary battery. In addition, the Shuo Erbo USB fast charging lithium battery uses the low discharge technology. For products with low daily use frequency, the battery can better lock the power and extend the use time.       

The USB fast charging battery of Shuo Erbo innovates to use lithium battery as battery cell. The advantages of lithium battery and better optimization of internal structure enable Shuo Erbo to maintain constant current status in a wide voltage range, and has obvious advantages in charging time and convenience. If the home is mainly composed of dry batteries and Ni MN batteries, and the battery consumption is relatively large, Shuerbo's fast charging battery is undoubtedly a very good alternative.

Shuerbo USB fast charging battery is an innovative product that everyone can think of but can't do. Not only can it save the user's use cost, but also because of the safety of lithium batteries compared with alkaline batteries containing mercury, the Shuo Erbo USB fast charging battery can also be more environmentally friendly. It is a battery responsible for the environment, and it is worth trying. In addition, the cap connector can be designed better, and the cap and internal connection will be a little loose. I hope it can be improved.
