Li ion Cylindrical Rechargeable Battery Cell 18650 1500mAh 15C

Category: Tags: ,

Summary of 18650 1500mAh 15C 18650 Li-ion Battery​

This  battery is a high-drain rechargeable cell designed for applications that require strong, stable current output in a compact form factor. With a nominal voltage of 3.7V and a continuous discharge capability of up to 22.5A, it delivers reliable performance under heavy loads while maintaining low internal resistance and good thermal stability. Supporting over 500 charge cycles (up to 1000 with proper use), this battery balances durability, safety, and efficiency, making it an eco-friendly alternative to disposable cells. Its high C-rating makes it ideal for power tools, drones, e-bikes, RC vehicles, and other devices that demand rapid current bursts and consistent voltage under load.

❓ FAQ – Frequently Asked Questions

Q1: What does 15C battery mean?

A: 15C battery means it can safely discharge current at 15 times its rated capacity. For a 1500mAh battery, this equals a continuous discharge current of 22.5A (1.5A × 15).

Q2: Is 15C enough for airsoft?

A: Yes, a 15C battery is generally sufficient for most airsoft guns, especially standard AEGs with stock or mildly upgraded motors. Higher-stress setups with high-speed motors or strong springs may benefit from a higher C-rating to ensure faster trigger response and reduced voltage sag.

Q3: How do you wake up a dead lithium battery?

A: A “dead” lithium battery can sometimes be woken up by slowly charging it with a smart charger that has a low-voltage or recovery mode. If the voltage is extremely low or the battery shows swelling or overheating, it should not be revived and must be replaced for safety.

Q4: Is it okay to trickle charge a lithium-ion battery?

A: No, lithium-ion batteries are not designed for continuous trickle charging like lead-acid batteries. They should be charged with a proper CC/CV charger that stops charging at 4.2 V to avoid overcharging and reduce safety risks.

Q5: What are common voltage problems with 18650s?

A: Common voltage problems with 18650 batteries include over-discharge below about 2.5 V, which can cause permanent capacity loss, and over-charge above 4.2 V, which increases safety risks. Voltage sag under high load is also common, often caused by high internal resistance or aging cells.
