The addition of functions such as taking photos, games, and surfing the Internet has made the mobile phone a must-have for thousands of people. The mobile phone accessories that have emerged as a result have become the focus of consumers, especially as the battery for mobile phones. The original electricity price is expensive, and the domestic battery is mixed. How to buy a battery with excellent price and excellent performance, this is to start from the structure of the battery.
The mobile phone battery is composed of three parts: lithium ion battery, protection circuit (PCM), and outer casing. The quality of the battery determines the life and endurance of the battery. The way to understand the battery is very simple: the information on the battery cover and the battery can be removed at a glance.
We chose Hong Kong Hongtian Wisky brand gold collar partner battery to interpret the battery knowledge:
First of all, the appearance of the commercially available mobile phone battery is smooth and complete, the logo is clear and complete: model, nominal voltage, rated capacity, positive and negative poles and production date. This is just the surface data. We need to know the actual brand model and performance parameters of the battery. You need the next step of disassembly.
When we carefully tear open the battery pack, some letter marks will be found on the aluminum shell. For example, the gold collar partner battery on the right side of the figure is TMB. What does this letter cell mean?
The TMB marked on the gold-collar battery cell is actually the brand of the battery. At present, most of the mobile phone batteries use lithium-ion batteries. Domestic brands are well-known: TMB Tianmao, BK BAK, BYD BYD, LS Tianjin Lishen, among which TMB is the most widely used battery for brand batteries. It is characterized by high battery capacity, standby time and original power, and high cost performance.
The quality of the battery mentioned above has a direct relationship with the endurance of the mobile phone, but the battery itself also needs both internal and external protection: the outer casing structure of the low-temperature and low-pressure injection molding process has improved the "outside", advanced low-pressure injection molding process technology. Use imported materials to maximize the capacity to maximize the battery, so that the battery meets the requirements of insulation, moisture, water and chemical corrosion. The "inner" off PCM protection board is used to prevent the battery from overcharging, overdischarging or overcurrent damage to the battery. The Hong Kong Hongtian Wisky brand battery in the picture is a high-end brand lithium battery protection IC, the advantages of which are It has played a great role in ensuring the overall quality of the battery and the protection of the mobile phone.
In addition to the gold collar partner, the WISKY brand has another flash battery.
Summary: To choose a mobile phone battery with long standby time, good quality, comprehensive after-sales and good value for money, you can start with the construction of the battery to understand. Hong Kong Hongtian Wisky brand battery from Tianmao TMB battery, as well as high-end brand lithium battery protection IC, to the shell material and advanced production technology, can be regarded as the high-quality representative of the domestic mobile phone battery brand, and the original brand battery In comparison, the biggest advantage is the high cost performance. For friends who want to buy more than one battery, Wisky brand battery is undoubtedly a good choice.
