Part 1. What Does 603040 Battery Mean?

The name “603040” refers to the battery’s physical dimensions: 6mm in thickness, 30mm in width, and 40mm in length. This compact size makes it an ideal choice for portable and space-constrained devices, while the “680mAh” represents the battery's capacity, which is 680 milliampere-hours. This means the battery can supply 680 milliamps of current for one hour, or a lower current for a longer period, offering efficient and reliable performance.

Part 2. Chemistry

The 680mAh 603040 is a lithium polymer (LiPo) battery. LiPo batteries are known for their high energy density, lightweight nature, and flexibility in design. They use a gel-like electrolyte instead of the liquid electrolyte found in traditional lithium-ion batteries, which results in a thinner, more compact design. LiPo batteries also offer better safety performance, reduced risk of leakage, and can be shaped to fit into various forms. This makes the 680mAh Li-ion battery an excellent choice for modern electronics where space and power efficiency are crucial.

Part 3. What is KC, UL1642?

The 680mAh 603040 Li-ion battery is certified with KC (Korea Certification) and UL1642 certifications. KC certification ensures the battery meets the safety and quality standards required by Korean authorities. UL1642 is a safety standard for lithium batteries, ensuring that the battery is safe to use in a wide range of applications, particularly where safety is of the utmost importance, like in medical devices and consumer electronics. These certifications guarantee that the 680mAh Li-ion battery meets rigorous safety and quality standards, providing customers with peace of mind.

The Connector Specification is Molex 51021, a high-quality connector known for its secure connection and reliability. Together, these components ensure that the battery integrates smoothly into various devices and maintains a strong electrical connection.

Part 6. How Long Can a 680mAh Battery Last?

The lifespan of the 680mAh Li-ion battery depends on its usage, environment, and maintenance. Typically, the battery has a cycle life of approximately 300 cycles, meaning it can be charged and discharged around 300 times before its performance starts to degrade. Proper care, such as avoiding extreme temperatures and overcharging, can help extend the battery’s life. If used in applications with moderate power demands, the battery can last for several years before needing replacement.

Part 7. Charging and Maintenance

To get the most out of your 680mAh Li-ion battery, it's important to follow proper charging and maintenance practices:

- Charging Voltage: The battery charges at a maximum of 4.2V.

- Charging Current: The typical charging current should be between 0.5C to 1C. This means the battery should be charged at half to one times its capacity (340mAh to 680mAh) for optimal performance.

- Temperature Range: Charge the battery in temperatures between 0°C and 45°C. Charging outside this range can damage the battery.

- Storage: Store the battery in a cool, dry place, and avoid exposing it to temperatures below -20°C or above 45°C. A temperature range of -20°C to 45°C is ideal for storage.

By following these practices, you can ensure that the battery operates safely and efficiently for the long term.

In conclusion, the 680mAh 603040 Li-ion battery is a versatile and dependable solution for a variety of applications, providing high capacity, compact size, and enhanced safety.
