Everything you need to know about battery life
As vaping becomes more widespread, it is very important for every vaper to practice good vape battery safety. Learn about vape battery safety and explore our guide to tentative battery care. Vape batteries are used in box mods, vape starter kits, and a bunch of other vape mods. If you are new to vaping or have any specific vape battery questions, feel free to contact us any time.
3 reasons to avoid overcharging your batteries
Breaks and leaks
Every lithium battery has a max capacity. Batteries can be compared to a balloon. When your battery is not charged, it's just like an unfilled balloon. It has the potential to be filled with air (electrical charge). The second you plug an air hose in (charging cable), this balloon starts filling. When a balloon is completely filled, any additional air puts stress on the balloon. Forcing additional charge into a fully charged battery puts stress on the battery.
Most vaping battery chargers and batteries themselves have mechanisms to stop the flow of charge. But every now and then, a bit of charge will leak of higher voltage charging filling it just a tiny bit more. This stretches out the battery and will slowly deteriorate the battery's charge capacity. Lower grade batteries and chargers often leak additional charge into a full battery.
Overcharge leads to overheat
We recommend cutting your li-ion batteries from charge once reaching peak to avoid stress/strain of your vape batteries. The stress of charging more than necessary can cause the battery to overheat more frequently. Since there is excess charge in the battery, each pull on the vape will try discharge that extra energy straining the battery significantly. Furthermore, the stress manifests in various ways, such as battery cracks. The outer casing can form tiny cracks due to overheating and rapidly cooling, which is not a good sign. Keep it up long enough and those cracks can penetrate to the actual lithium-ion core, which can be toxic. This is where those horror stories about vape batteries exploding come from. With an overcharged battery and too much strain on said battery, it's an unfortunate circumstance that in some casing batteries can explode.
Overcharging shortens battery life
Batteries can only be recharged for so many cycles before their lifespan begins to shorten. Leaving batteries overcharging will result in trickling of constant energy charge circulating into the battery. This results in the gradual loss of the ability to hold a charge. Additionally, higher voltage charge also stretches the temporary capacity of the battery degrading the capacity sooner.
Prolong the lifespan of your batteries by avoiding continuous charging and maximizing your charge cycles.
Guidelines for charging Lithium ion batteries
- charge batteries at a moderate temperature (50 to 86 degrees F) - Charge acceptance is lower in cold and hot environments. This means the battery has a harder time charging up when it is too cold or hot.
- Discontinue using charger and/or battery if the battery gets excessively warm - A hot battery means some of its charge is physically leaking out of the battery. This starts to happens when your battery has been used many times. This can also mean your charger isn't doing a good job of transferring energy efficiently
- Apply some charge to an empty battery before storing (40/50 percent is ideal) - Do not leave a dead battery idle. It is strongly recommended to put some charge back into the battery as soon as possible. This minimizes total capacity loss over time
How often should vapers replace batteries?
Most 18650 lithium ion batteries are rated for 300-500 cycles. This cycle count usually runs its course in 1-2 years depending on personal usage. We recommend that every vaper replaces their batteries once a year. Take the safer route and replace batteries annually instead of pushing them close to their max cycle count. They aren't expensive and it's better to be safe than sorry.Shop vape batteries
