STRUCTURE AND DIMENSION
HANDLING PRECAUTIONS AND GUIDLINE
1.Charging for Round Lithium Polymer Battery
1.1 Charging current:
Charging current should be less than maximum charge current specified in the Product Specification. Charging with higher current than recommended value may cause damage to cell electrical, mechanical and safety performance and could lead to heat generation or leakage.
1.2 Charging voltage:
Charging shall be done by voltage less than that specified in the Product Specification (4.2V/cell). Charging beyond 4.25V, which is the absolute maximum voltage, must be strictly prohibited. The charger shall be designed to comply with this condition. It is very dangerous that charging with higher voltage than maximum voltage may cause damage to the cell electrical, mechanical safety performance and could lead to heat generation or leakage.
The round lithium polymer battery shall be charged within 10°C~45°C range in the Product Specification.
2. Discharging for Round Lithium Polymer Battery
2.1 Discharging current:
The cell shall be discharged at less than the maximum discharge current specified in the Product Specification. High discharging current may reduce the discharging capacity significantly or cause over-heat.
2.2 Discharging temperature:
The cell shall be discharged within –20°C~60°C range specified in the Product Specification.
It should be noted that the round lithium polymer battery would be at over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over-discharging, the cell shall be charged periodically to maintain between 3.6V and 3.9V. Over-discharging may causes loss of cell performance, characteristics, or battery functions. The charger shall be equipped with a device to prevent further discharging exceeding a cut-off voyage specified in the Product Specification. Also the charger shall be equipped with a device to control the recharging procedures as follows: The round lithium polymer battery pack shall start with a low current (0.01C) for 15-30 minutes, i.e.-charging, before rapid charging starts. The rapid charging shall be started after the (individual) cell voltage has been reached above 3V within 15-30 minutes that can be determined with the use of an appropriate timer for pre-charging. In case the (individual) cell voltage does not rise to 3V within the pre-charging time, then the charger shall have functions to stop further charging and display the cell/pack is at abnormal state.
STORAGE OF ROUND LITHIUM POLYMER BATTERY
1. Ambient temperature: 23°C±5°C
2. Relative Humidity: 65±20%
3. Please activate the round lithium polymer battery once every 3 months according to the following method:
Charge at 0.2C to 4.2V, rest 5 min, then discharge with 0.2C to 3.0V/cell, rest 5 min, then charge at 0.2C to 3.9V.

Small medical devices will have a subversive impact on health management practices
Medical devices are ubiquitous in our lives, but as a sub-area of the pharmaceutical industry, its market is still relatively small, and it is not as important as drugs. It has neither a comprehensive technological breakthrough nor even a unified technology. The direction, every progress is only the doctor will pay attention. But all the development is put together, but it will have a subversive impact on the health industry, that is, each of us manages our health.
At the level of the world, medical resources are scarce. To solve this problem, we need to do the following three things: let each person get sick less; get sick as soon as possible, and treat as quickly as possible; chronic diseases can be well managed. And medical devices can help people in these three areas. At the same time, various trends also have a large market for the future of medical devices.
In terms of communitization, relevant data shows that consumers who have been to retail clinics in the United States have grown from 10% in 2007 to 35% in 2015. In 2016, the number of retail clinics in the United States reached 3,000. The community and remoteization of this kind of health service have brought about a new trend, called “instant detection.” The full name of the word, Point-Of-Care Testing, referred to as POCT, is the monitoring, diagnosis, and treatment of the site where the disease or event occurs. It requires medical devices to be miniaturized, portable, simple to operate, and low in cost.
Currently, China is moving towards a similar model of grading, but it is just getting started. China has a large population base and certainly needs more community clinics like the American Snack Clinic. Therefore, in the future, small medical devices will have a lot of room to play.
In addition to the transformation of the medical system model, the development of other specialized medical institutions has also increased the demand for medical devices. At present, the areas where capital is more focused include specialized hospitals and small medical institutions, including medical beauty, rehabilitation, community medical care, and also require a large number of instant monitoring devices and plastic surgery and rehabilitation equipment.
From the perspective of a more extended demographic structure, China’s population aging has seen the first peak of the elderly population during the “Twelfth Five-Year Plan” period, and the proportion of the elderly population has increased from 13.3% to 16%. It means that the demand for health care for the elderly has increased dramatically. The existing hospital beds and nursing capacity have been challenging to meet the needs of the elderly, and the consequent rehabilitative care for the elderly has gradually shifted to hospitals and clinics in families and communities.
The trend of the above three demand sides will promote the development of intelligent, portable and miniaturized medical device products for the detection, diagnosis, treatment, and rehabilitation care, resulting in the long-term rapid growth of medical devices.
There are many types of medical device subdivisions. In general, it can be divided into small in vitro diagnostics, small medical imaging instruments, genetic testing, rehabilitation, and high-end consumables, especially 3D printing. Here we introduce the field of application that is currently widely used and is in the rapid development phase: in vitro diagnostics.
80% of our clinical diagnostic information comes from in vitro diagnostics, which play an essential role in health assessment and disease diagnosis. Before the 1980s, laboratory testing was centralized, and all tests were performed in the laboratory before the results were returned to the patient. But now, the most common blood sugar test has been transferred from the laboratory to the immediate monitoring of patient care. We see that small medical devices have a large market space in this field. One of the markets is what we call “instant detection.” The precise definition of in vitro and immediate detection (IVD) refers to the acquisition of clinical diagnostic information by detecting blood and urine tissues and secretions in vitro. There are many ways to check IVD, which can be divided into the biochemical diagnosis, immunodiagnosis, molecular diagnosis, hematology, microbiology diagnosis, urine diagnosis, etc. Among them, biochemistry, immunity, and molecular are the most important in daily medical diagnosis.
The popularity of small medical devices reflects the new demands of the health and wellness industry, and the development of small medical devices will also change the face of the health industry. With the changes in population structure, the development of big data and Internet of Things technologies, more and smaller medical devices will enter community clinics and enter our lives. The above mentioned are just some of the more clear applications. Small medical devices are an up-and-coming market. As investors, we look forward to finding many high-tech companies with growth potential in this field.
