CELL 2000 mAh Single Cell Lithium-ion Rechargeable Polymer Battery

A 2000 mAh Single Cell Lithium-ion Rechargeable Polymer Battery is a higher-capacity, lightweight, and versatile battery commonly used in portable electronics. Here’s a breakdown of its key features:

1. Capacity:

• With a 2000 mAh (2 Ah) capacity, this battery can supply 2000 milliamps (2 amps) for 1 hour, or a lower current over a longer period. This makes it suitable for devices that require moderate to high power consumption for extended periods.

2. Chemistry:

• This battery uses Lithium-ion (Li-ion) technology with a Lithium Polymer (LiPo) format. Li-ion batteries are well-known for their high energy density, long lifespan, and lighter weight compared to other types of rechargeable batteries. The LiPo version adds flexibility to the battery’s shape and size, allowing it to fit into more compact or custom designs.

3. Rechargeability:

• As a rechargeable battery, it can be charged and used multiple times. Typically, you can expect a lifespan of hundreds to thousands of charge cycles before the battery’s capacity begins to degrade.

4. Voltage:

• The battery generally has a nominal voltage of 3.7V, with a fully charged voltage of 4.2V and a discharge cutoff voltage of around 3.0V to 3.2V. Discharging the battery below this cutoff voltage can damage the cell, so it’s important to use a proper battery management system (BMS) or protection circuit.

5. Applications:

• Due to its 2000 mAh capacity, this battery is well-suited for devices that need a decent amount of power but still benefit from a lightweight and slim design. Common applications include:
  • Smartphones and tablets
  • Portable drones and RC vehicles
  • Bluetooth speakers
  • Wearable electronics like smartwatches and fitness trackers
  • Power banks and backup power supplies
  • Portable lighting and LED projects
  • Electric shavers, cameras, and other personal electronics

6. Form Factor:

• This battery is in the polymer format, meaning it can be molded into a variety of shapes and sizes to fit specific design needs. The flexibility of the polymer makes it ideal for slim and compact devices.

7. Safety:

• Lithium-ion batteries, including the 2000 mAh polymer version, typically feature built-in safety protection circuits to prevent:
  • Overcharging
  • Over-discharging
  • Short circuits
  • Excessive current draw
• These protections help to ensure the safety and longevity of the battery, although it’s still essential to follow manufacturer guidelines for charging and usage to avoid any issues.

8. Charging:

• These batteries require a specialized charger that is compatible with 3.7V Li-ion cells. Overcharging or undercharging should be avoided to maintain the battery’s performance and lifespan. A charge management circuit is often used to ensure proper charging, as Li-ion batteries are sensitive to voltage extremes.

9. Advantages:

• High energy density, meaning it stores a significant amount of energy relative to its weight and size.
• Long cycle life, which means it can be used and recharged for many years with proper care.
• Compact and flexible design makes it adaptable to a wide range of devices and form factors.
• Lightweight compared to other battery types like NiMH or lead-acid.

10. Disadvantages:

• While Li-ion batteries are safe when used correctly, they can pose a risk of thermal runaway or fire hazards if damaged, overcharged, or improperly handled. Always ensure proper protection circuits are in place.

In summary, the 2000 mAh Single Cell Lithium-ion Rechargeable Polymer Battery is a great choice for medium-to-high power devices where space, weight, and reliability are key. Its higher capacity makes it ideal for gadgets needing a bit more runtime, while the polymer format allows for a flexible design to fit into a variety of products.
