Choosing the right battery depends on your specific vaping style and device requirements. Different batteries offer varying capacity ratings and discharge rates, so understanding your mod's specifications is essential.
For sub-ohm vaping, you'll want batteries with higher continuous discharge ratings. Meanwhile, if you're using higher resistance coils, capacity might be more important than raw power output. The key is matching your battery's capabilities to your device's demands.
IIt's worth noting that mishandling or misuse can lead to potential hazards such as venting, burns, or explosions. This isn't meant to scare you – just to emphasise why proper knowledge and handling of devices and vape juice are so important.
Are all 18650 batteries the same size?
Yes, genuine 18650 batteries follow standardised dimensions - 18mm diameter and 65mm length. However, you'll encounter variations between flat top and button top designs, which can affect compatibility with certain devices.
Some protected cells might be slightly longer due to additional safety circuitry, so always check your device's battery compartment specifications before purchasing.
What's the difference between flat top and button top 18650s?
Flat top batteries have a completely flat positive terminal, whilst button top versions feature a small raised button. Your device's design determines which type you'll need - some mods only work with one style or the other.
Most modern vape mods are designed to accommodate both types, but it's always worth checking your manual or contacting the manufacturer if you're unsure.
How long do 18650 vape batteries last?
Battery lifespan depends on several factors including usage patterns, charging habits, and overall care. Quality 18650s typically handle hundreds of charge cycles before showing significant capacity degradation.
For daily vaping, you might find yourself charging every day or two, depending on your device's power consumption and the battery's capacity rating.
Do I need a special charger for 18650 batteries?
Yes, you'll need a dedicated lithium ion battery charger designed for 18650 cells. Using the wrong charger or charging method can be dangerous and will likely damage your batteries.
Quality chargers offer multiple safety features and proper charging algorithms that help maximise battery life whilst keeping you safe.
Can I use any 18650 battery in my vape mod?
Not necessarily. Your mod will have specific requirements for battery specifications, particularly regarding continuous discharge ratings. Using batteries that don't meet these requirements can be unsafe and may damage your device.
Always check your mod's manual for recommended battery specifications and stick to reputable brands with proven track records in the vaping community.
