What is 18650 Rechargeable Lithium Battery: How to Custom?

The 18650 rechargeable lithium battery is a powerhouse in the world of energy storage, widely used in electric vehicles, power tools, and portable electronics. As a top Chinese battery manufacturer, Yilai Power excels in delivering high-quality lithium ion batteries, including the popular 18650 cells. This article dives into what makes the 18650 battery special, its performance, safe storage practices, and how Yilai Power’s customization solutions can tailor these batteries to your needs.

What is 18650 Rechargeable Lithium Battery?

The 18650 rechargeable lithium battery is a cylindrical lithium ion battery measuring 18mm in diameter and 65mm in length—hence the name "18650." Renowned for its high energy density and rechargeability, it’s a go-to choice for applications requiring reliable, long-lasting power. From electric vehicles to consumer electronics, these batteries deliver exceptional performance in a compact form.

Are All 18650 Batteries Rechargeable?

Yes, 18650 batteries are inherently rechargeable, belonging to the lithium ion battery family. They are designed for multiple charge-discharge cycles, making them ideal for repeated use. While non-rechargeable lithium batteries exist, they typically don’t come in the 18650 format. Yilai Power ensures that our 18650 rechargeable lithium batteries are optimized for safety and longevity when paired with proper charging equipment.

Performance and Cycle Life of 18650 Rechargeable Lithium Battery

The 18650 rechargeable lithium battery stands out due to its impressive performance metrics, including capacity, C-rating, and cycle life. These attributes make it a versatile option for high-demand applications.

Capacity, C-Rating, and Cycle Life of 18650 Cells

Capacity: Measured in milliampere-hours (mAh), the capacity of 18650 batteries typically ranges from 2000mAh to 3500mAh. This determines how long the battery can power a device before needing a recharge.

C-Rating: The C-rating reflects the battery’s maximum discharge rate. For instance, a 3000mAh battery with a 10C rating can safely deliver 30A, perfect for power tools or electric vehicles.

Cycle Life: The cycle life indicates how many charge-discharge cycles the battery can endure before its capacity significantly declines. Yilai Power’s 18650 batteries often exceed 1000 cycles, offering exceptional durability.

As a leading lithium battery manufacturer, Yilai Power engineers 18650 batteries to deliver top-tier performance, ensuring they meet the needs of diverse industries.

How to Store 18650 Batteries Safely？

Proper storage of 18650 batteries is essential to maintain their performance and prevent safety risks like short circuits or capacity loss.

18650 Battery Storage Environment

To keep your 18650 batteries in optimal condition:

Store them in a cool, dry environment, ideally between 15°C and 25°C.

Avoid extreme temperatures and high humidity, which can degrade battery health.

Keep batteries away from direct sunlight and flammable materials.

18650 Battery Storage Package

Use insulated cases or the original packaging to prevent contact between terminals.

Store 18650 batteries at 40%–60% charge for long-term preservation.

Isolate each battery to avoid accidental shorting with metal objects.

Following these tips ensures your 18650 rechargeable lithium batteries remain safe and ready for use.
