External batteries, such as 18650 and 21700 cells, are widely used in vape devices for their reliability and performance. However, to get the most out of these powerhouses, it's crucial to charge them properly. In this post, we’ll guide you through the best practices for charging your external batteries safely and efficiently. We’ll also highlight some excellent charging bays available at Oxford Vapours, including the Xtar MC4s, Xtar VC2SL, and Xtar VC4SL.
Why External Battery Care Matters
Proper charging of your external batteries not only extends their lifespan but also ensures safe usage. Overcharging, undercharging, or using an inappropriate charger can degrade battery performance and, in some cases, pose safety risks. By following the right practices and using reliable chargers, you can maximise the longevity of your batteries while vaping with peace of mind.
Best Practices for Charging Your 18650/21700 Batteries
1. Use a Dedicated External Charger
While many vape devices allow for USB charging, an external charger is always a safer and more efficient option. Dedicated chargers are designed to provide stable current, minimise heat, and offer protective features like overcharge prevention.
2. Choose the Right Charger for Your Needs
Different chargers offer varying levels of functionality. Whether you’re charging a single battery or multiple cells simultaneously, selecting the right charging bay is key:
-
Xtar MC4s: A compact and budget-friendly option for vapers who need a no-fuss charger. This 4-bay charger automatically adjusts charging current based on the battery's specifications, making it ideal for beginners.
-
Xtar VC2SL: A step up in functionality, this charger features a detailed LCD display that shows battery status, voltage, and charging speed. It’s perfect for users who want greater insight into their battery's health.
-
Xtar VC4SL: The premium choice for serious vapers. With four bays, a clear LCD screen, and advanced features such as independent charging for each slot, this charger offers the ultimate in precision and safety.
3. Charge in a Cool, Well-Ventilated Area
Heat is the enemy of lithium-ion batteries. Always charge your batteries in a cool environment away from direct sunlight or heat sources. Ensure the charger itself has adequate ventilation to prevent overheating.
4. Avoid Overcharging
Modern chargers like the Xtar range automatically stop charging once the battery reaches full capacity, protecting against overcharging. However, it’s still good practice to remove batteries promptly when charging is complete.
5. Inspect Batteries Regularly
Before charging, check your batteries for any signs of damage, such as dents or torn wraps. Damaged batteries should never be used or charged, as they can pose a serious risk.
6. Store Batteries Safely When Not in Use
When not in your vape device or charger, store batteries in a protective case to prevent accidental short circuits. Never leave loose batteries in pockets or bags with metal objects like keys or coins.
