Understanding E-Cigarette Battery Types

Lithium Ion Batteries

Most modern e-cigarettes use lithium-ion batteries, which are powerful and efficient but require specific safety measures (1). Lithium-ion batteries are designed to safely manage the discharge of energy, but improper use can lead to rapid discharge and safety risks. The metal interior of lithium-ion batteries must be protected from damage to prevent short circuits or other hazards. These batteries come in various forms, from built-in units in cigalikes to removable cells in advanced devices. Each type has unique safety considerations that users must understand.

Built-In Batteries

Built-in batteries, commonly found in prefilled vape starter kits, are generally safer for beginners as they’re designed with integrated safety features. These built-in batteries typically include overcharge protection to prevent charging beyond safe voltage levels. They are also equipped with various safety protections, such as short circuit and overheat prevention, to enhance user safety. However, they still require proper charging and handling practices to maintain safety and performance.

External Batteries

Removable batteries offer more flexibility but demand greater responsibility from users. It is crucial to use the correct charger for external batteries to avoid damage or safety hazards. Many of the more powerful E cigarette devices rely on external batteries, so proper handling and charging are essential for safety. These cells must be handled with extreme care, stored properly, and replaced when they show signs of wear or damage.

Proper Charging Practices

Charging your E-Cigarette battery correctly is crucial for safety and longevity. Manufacturers recommend charging E-Cigarette batteries according to specific guidelines to ensure safety. Always use the charger provided by the manufacturer or a certified replacement. Generic chargers may not have the proper voltage regulation, potentially leading to overcharging or overheating (2).

You should never leave your device charging unattended for extended periods. While most modern devices have built-in safety features to prevent overcharging, it’s still best practice to monitor the charging process. Unplug your device once it reaches full charge to prevent unnecessary stress on the battery. Monitoring the recharging process helps prevent overcharging and overheating which can damage the battery.

One of the best pieces of advice we can give is to avoid charging your E-Cigarette overnight or while you’re away from home. This simple precaution significantly reduces the risk of overheating or other charging-related issues. Set reminders to check on your device during charging sessions.

Be sure to use only appropriate charging surfaces. It is essential to place your device on a flat surface for safe charging. Never charge your device on soft surfaces like beds, couches, or pillows, as these can trap heat and create fire hazards. Hard, flat surfaces with good ventilation are ideal for safe charging.

Temperature Considerations During Charging

Temperature plays a critical role in battery safety, and it is ideal to charge your e-cigarette in environments between 32°F and 95°F (0°C to 35°C). Extreme temperatures can damage the battery and create safety risks (3). Charging batteries outside the recommended temperature range increases the fire risk.

If your device becomes unusually warm during charging, disconnect it immediately and allow it to cool down. Excessive heat during charging often indicates a problem with either the battery or the charging system.

Daily Handling and Usage Safety

Proper daily handling of your e-cigarette battery prevents accidents and extends device life. Always turn off your vape device when not in use, especially when carrying it in a pocket or bag. Storing batteries or devices loose in a pocket or bag can increase the risk of accidents, such as accidental activation or short circuits.

It is vitally important to keep your device away from other metal objects like keys, coins, or jewellery when storing or transporting. Contact with other metal objects can cause a short circuit in the battery terminals, leading to overheating or even fire. One man found this out the hard way, causing serious burns when his vape short-circuited in his pocket (4).

You should regularly inspect your device for signs of damage, including cracks in the casing, damaged charging ports, or loose connections. Any visible damage warrants immediate attention and potentially device replacement.

Take the time to clean your device regularly, paying special attention to charging ports and battery connections. Use a dry cloth or cotton swab to remove debris and e-liquid residue that could interfere with proper operation.

Storage - Best Practices For Vape Batteries

Proper storage significantly impacts battery safety and longevity (5). Store your e-cigarette battery in a cool, dry place away from direct sunlight and heat sources. Excessive heat can cause batteries to degrade rapidly and potentially become dangerous. Avoid storing batteries in places exposed to extreme temperatures or direct sunlight.

If you won’t be using your device for an extended period, store it with a partial charge (around 40-60%). Completely drained or fully charged batteries can deteriorate faster during long-term storage.

For devices with removable batteries, consider investing in proper battery cases for storage and transport. These cases prevent accidental contact with metal objects and protect the batteries from physical damage.

Keep spare batteries and devices away from children and pets. Even though e-cigarettes are designed for adult use, proper storage prevents accidental access and potential harm. Inspect and clean your batteries regularly to maintain safety and optimal performance.

Following these storage recommendations is considered good practice for battery safety.

Recognising Warning Signs

Learning to identify potential battery problems early prevents dangerous situations. Watch for these warning signs that indicate your battery may need attention or replacement. (6)

Unusual heat generation during normal use suggests battery problems. While slight warming is normal, excessive heat indicates potential failure and safety risks.

Rapid battery drain or inability to hold a charge signals battery degradation. When your device requires frequent charging or dies quickly after charging, it’s time to consider replacement.

Physical changes like swelling, discoloration, or unusual odours are serious warning signs. If you notice any of these, stop using the battery immediately. Severe battery failures can result in explosion or even explosions, so prompt action is essential to prevent accidents.

Inconsistent performance, such as fluctuating power output or unexpected shutdowns, may indicate battery issues. These symptoms are common battery related issues that require attention and may warrant professional evaluation or device replacement.

Maintenance and Care Routines

Establishing regular maintenance routines keeps your E-Cigarette battery in optimal condition and keeps you aware of when you are going to need replacements. Clean your device weekly, focusing on areas where e-liquid might accumulate and cause problems. While E-Cigarette tanks are designed to keep the e-liquid where it is supposed to be - inside the tank - liquids have a habit of getting into every nook and cranny so a regular maintenance appointment means you have the best chance of spotting things like a crack in the tank or a perishing seal.

Check all connections monthly to ensure they're clean and secure. Loose connections can cause poor performance and potential safety issues.

Monitor charging times and battery performance regularly. Keeping track of these metrics helps you identify gradual changes that might indicate developing problems.

Replace batteries according to manufacturer recommendations or when performance significantly degrades. Don't attempt to extend battery life beyond safe limits.

Emergency Procedures

Despite best efforts, battery emergencies can occur. Battery malfunctions can result in fires, and quick action is necessary to prevent causing fires. Knowing how to respond quickly and safely minimises risks and potential damage. (7)

If your device becomes extremely hot, stop using it immediately and place it on a non-flammable surface away from people and combustible materials. Allow it to cool completely before handling.

In case of battery leakage, avoid direct contact with the leaked material and ventilate the area. Dispose of the damaged device according to local hazardous waste guidelines.

If you notice smoke or unusual odours from your device, evacuate the immediate area and contact emergency services if necessary. If a battery incident leads to fire or smoke, contact the fire service for assistance. Never ignore these serious warning signs.
