The battery in a vape is an important component that provides energy for the device to operate. Understanding the battery in a vape not only helps optimize performance but also ensures safety for users.
1. Common battery types in vapes
The batteries used in vapes are typically Lithium-ion (Li-ion) batteries due to their high capacity, strong discharge capability, and compact size. Common sizes include:
- 18650: The most common battery type, measuring 18mm x 65mm.
- 20700 and 21700: Larger capacity and higher discharge capacity than 18650.
- 18350: Small size, suitable for compact devices.
- 26650: Larger than 18650, offers higher capacity, but less popular.
2. Important parameters of vape batteries
Capacity:
- Measured in milliampere-hours (mAh).
- The higher the capacity, the longer the usage time.
Discharge Rate:
- Measured in amps (A), represents the maximum current the battery can safely supply.
- High discharge batteries (20A, 25A, or higher) are often used for sub-ohm vapes and high power devices.
Voltage:
- Li-ion batteries typically operate at a nominal voltage of 3.7V and can be fully charged up to 4.2V.
- The lowest safe voltage is usually 2.5V – if it falls below this level, the battery may be damaged.
3. Choose the right battery
- Mechanical mod (Mech mod) : Requires a battery with high discharge capacity (at least 20A or more), because there is no regulation circuit to protect the device.
- Regulated mod : Less stringent requirements, but still choose batteries from trusted brands.
- Reputable battery brands : Sony, Samsung, LG, Molicel...
4. Safety when using vape batteries
Li-ion batteries are very efficient but also sensitive, so care must be taken when handling them. Here are some safety tips:
- Do not use damaged batteries: Torn or deformed batteries may cause short circuits.
- Use the correct battery: Make sure the battery has a discharge capacity appropriate to the capacity of the device.
Proper storage:
- Use battery case to avoid short circuit.
- Do not leave the battery in high temperature or humid environment.
Charge properly:
- Use only high quality chargers.
- Do not leave the battery charging overnight or unattended.
Periodic check: Replace old, worn or abnormal batteries.
5. Risks of improper battery use
Thermal Runaway :
- May occur when the battery is overloaded, overheated, or short-circuited.
- Consequences may be fire or explosion.
Over-discharge:
- Reduces battery life and risks damage.
Overload discharge current:
- Using a battery that does not meet the discharge current requirement may result in fire or explosion.
6. Conclusion
The battery in a vape plays an important role not only in performance but also in safety. Choosing the right battery, using it and storing it properly is essential to avoid risks and optimize the experience. For users, especially new users, learning about batteries thoroughly is the first step to ensuring safety and efficiency when using a vape device.
