Important Battery Safety Guidelines
WARNING: There are inherent risks associated with using specialist rechargeable batteries in e-cigarettes.
To ensure your safety and the longevity of your battery, you must adhere to the following guidelines. We are not liable for damage caused by improper use, storage, or handling of batteries.
- Charge Correctly: Never leave a charging battery unattended. Do not charge in excessively hot or cold environments, and do not leave on charge for more than 24 hours. Always use a charger that is in good condition and suitable for 21700 cells.
- Store Safely: When not in your device, always store batteries in a dedicated plastic battery case. Never carry loose batteries in pockets or bags where they can come into contact with metal objects (keys, coins), as this can cause a short circuit, explosion, or fire.
- Check Your Wraps: Do not use the battery if the outer wrapping (PVC wrap) is torn, damaged, or peeling. Do not use if the battery is dented, deformed, discoloured, or abnormally hot.
- Temperature Control: Store batteries at ambient temperature in a dry, well-ventilated place. Avoid excessive heat or cold.
- Do Not Mix: Never use different brands, ages, or models of batteries together in the same device. Always marry your batteries (charge and discharge them together as a set).
- Disposal: If a battery is damaged or leaks, dispose of it immediately in accordance with your local regulations. If liquid contacts your eyes, wash with clean water and seek medical attention immediately.
