Vape Battery Safety Information

At Royal Flush Vape, your safety comes first. Vape batteries are powerful, reliable, and safe when handled correctly. By following these simple guidelines, you’ll keep your vaping experience smooth, safe, and stress-free.

Safe Handling and Storage

Always treat your batteries with care.

• Never carry loose batteries in your pocket or bag — contact with keys, coins, or other metal objects can cause a short circuit or explosion.
• Use a protective battery case for carrying or storing spare batteries.
• Keep batteries clean, dry, and away from heat, cold, or direct sunlight.
• Avoid dropping, crushing, dismantling, or exposing them to water.
• Store them in a cool, dry place, and if unused for long periods, recharge and discharge occasionally to maintain performance.

Lithium-ion batteries are dependable but sensitive to misuse. Avoid overcharging, short-circuiting, or exposing them to extreme temperatures. Handle them with care and they’ll perform safely for a long time.

Understanding Battery Power and Charging

Every vape battery has two key ratings:

• Capacity (mAh) – measures how much energy it can store. A higher mAh means longer battery life.
• Continuous Discharge Rating (CDR or amps) – shows how much power the battery can safely deliver.
• Sub-ohm or cloud-chasing vaping requires a high amp rating (20A or more).
• MTL or nicotine salt devices work safely with moderate amp ratings.

To find your safe charging current, move the decimal point three places to the left in your battery’s mAh rating.
Example: 3500mAh = 3.5A maximum charging current.
Always follow the manufacturer’s guidelines and never exceed the recommended charge or discharge rate.

When charging:

• Use official or high-quality chargers — avoid cheap or unbranded ones.
• Don’t leave batteries charging unattended or overnight.
• Charge on a non-flammable surface and disconnect when fully charged.

If a Battery Is Damaged or Leaking

Stop using any battery that appears swollen, leaking, or damaged.

• Don’t touch leaking fluid.
• If it contacts skin or eyes, rinse immediately with water and seek medical attention.
• Dispose of damaged or old batteries safely at a proper recycling facility.

Remember, battery acid is toxic — handle all batteries with care and never try to open or repair one yourself.

Important Safety Reminders

• If swallowed, seek medical help immediately.
• Dispose of batteries and packaging responsibly.
• Always follow manufacturer instructions and keep product information for reference.

By following these simple precautions, you’ll ensure safe, reliable performance from your vape batteries — every time.
