Unlike standard AA or AAA batteries, the 18650 battery is larger and designed for high-power demands, providing excellent energy density for devices requiring sustained or intermittent high current. It is safe for use when paired with a protection circuit board (PCB) to guard against overcharging, over-discharging, and overcurrent, which can cause the battery to degrade or fail. It is important to handle Li-ion batteries carefully, as they are sensitive to mishandling and can be volatile if damaged.

Important Notes:

• This is a copy version of the 18650 cell, meaning the capacity and performance may vary depending on usage and charging parameters.
• It is not recommended for power-critical applications. For demanding tasks, you may prefer the Original Hongli 18650 cells.

Specifications:

• Voltage: 3.7V
• Capacity: 2000mAh
• Rechargeable: Yes
• Battery Size: 18mm (diameter) x 67mm (length)
• Charging Method: CC-CV (Constant Current - Constant Voltage)

Applications:

• Cordless Phones
• Small Drones
• Tablet PCs / GPS
• iPods, DVD, MP4 Players
• Mobile Backup Power Supply / Power Banks

Usage Instructions:

This battery is easy to incorporate into projects. You can solder the wires directly to the terminals or use a 18650 battery holder for easy replacement. Always avoid overcharging or discharging the battery beyond safe limits, as Li-ion batteries can accumulate gases that may cause explosions or fires. A Protection Circuit Board (PCB) is highly recommended to prevent such issues.
