Battery Safety Guidelines
Safe handling and charging of lithium-ion batteries is essential. While uncommon, battery malfunction may lead to overheating, venting, or fire if not properly managed. The following guidelines are provided to help reduce associated risks.
General Safety Tips
- Never leave charging batteries unattended. Charging should always occur under supervision in a well-ventilated, non-flammable area. Avoid charging overnight or while away from the charging location.
- Inspect batteries before each use. Look for signs of damage such as torn wraps, corrosion, leakage, discolouration, or dents. If damaged, discontinue use and recycle safely.
- Do not expose batteries to heat or direct sunlight. Avoid leaving batteries in vehicles, near heaters, or in enclosed spaces where heat can accumulate.
- Only use approved charging equipment. Use the supplied or manufacturer-approved charging adaptor. Avoid damaged or incompatible chargers. USB 3.0/3.1 ports (often marked with blue plastic) may exceed 1 A and should be avoided.
- Keep terminals clean and dry. Ensure battery contacts and charger terminals are free from dust, e-liquid, or debris before charging.
- Discontinue use if behaviour is abnormal. If a battery becomes hot, if the button sticks, or if charging cycles behave inconsistently, stop using it immediately and dispose of it through an appropriate facility.
Internal Batteries
Many vape devices include built-in lithium-ion batteries that are recharged using a USB cable and a wall adaptor. Note that a USB cable is not a charger on its own — it must be paired with a compatible adaptor.
If an adaptor is not supplied, use one that does not exceed 5 volts and 1 amp. Charging above these limits can damage the battery or device. Avoid using USB 3.0/3.1 ports, which may exceed safe current output levels.
Fully charge the device and disconnect once charging is complete. Even if the device supports pass-through functionality (vaping while charging), this may reduce overall battery life and is not recommended.
External Batteries
Devices that use removable batteries — such as 18650 lithium-ion cells — should be charged using a quality external charger. This provides better overcharge protection and helps balance cells more safely than onboard USB charging.
Do not carry loose batteries in your pocket or bag. If terminals come into contact with metal objects like keys or coins, they may short circuit and vent hot gas or liquid. Always store loose cells in a non-conductive battery case.
Married Batteries
For dual-battery or multi-battery devices, always use "married" batteries. These are batteries of the same brand, model, and age, charged and discharged together from the beginning. Mixing unmatched batteries can cause imbalance and reduce safety.
Charge married batteries using an external charger to maintain even power distribution between cells. Never mix different types or ages of batteries in the same device.
Important Notice
Lithium-ion batteries carry known risks, including overheating and fire. Users are responsible for proper handling, charging, and disposal. Before using any lithium-ion battery, it is recommended to familiarise yourself with independent safety information. For example, search “lithium-ion battery hazards” to review correct storage and safety practices.
