Vaping is a fun and convenient way to get your daily nicotine hit. If you’ve been doing it for a while, you may have invested in a vaping device and all is going well.

But nothing lasts forever, and sooner or later your vape’s battery will start to fail. It’s a simple fix to replace the vape battery, but ignoring the problem can be dangerous.

Thankfully, there are some warning signs to look out for so your vape doesn’t end up becoming a health hazard. We’ve got some tips on what the signs are, some more uncommon issues with vape batteries, and how you can replace your battery when the time comes.

Let’s dive in.

Common issues with vape batteries

There are some tell-tale signs that give you a sense of whether your vape battery is in good health. Here are some of the most common issues with vape batteries.

Reduced battery life

This is one of the most common indicators that it may be time to replace the batteries in a vape. If the device isn’t holding charge as well as it used to or runs out of power quickly, then the battery may be faulty.

This is a typical issue if you’ve had your vape for some time. Batteries have a limited lifespan and will eventually lose their ability to hold a charge or deliver the necessary power to the device.

Unfortunately, overcharging can cause issues too by damaging the battery. Be sure to only charge the vape as needed.

Performance issues

If you’ve noticed that your vape isn’t working properly, then your battery might need replacing. Performance issues could look like the mod device not producing as much vapour as it used to, or if the vapour is not as hot or flavorful.

As the batteries begin to lose their ability to hold a charge or deliver power, the device may not be able to produce as much vapour or heat the coil. This delivers a far less satisfying vaping experience. If you’ve ruled out other factors like a bad coil or vape juice, then the battery may well be the issue.

Not charging

This is another classic sign that the batteries may be on the blink. If the batteries aren’t charging at all, then chances are they need replacing. You’ll also need to rule out that the charger itself isn’t faulty first.

Like with reduced battery life, age and overcharging are the two key causes for a battery not charging at all. Using low-quality or incompatible batteries can also lead to charging issues.

Voltage

The voltage in a vape is a measure of the electrical potential energy that the battery can provide. If the battery is faulty, this will cause the voltage to fluctuate when in use. If left, the voltage will drop too low and the vape will stop working altogether.

Some devices have a built-in battery level indicator that can help you to monitor the voltage of the batteries and anticipate when it's time to replace them. Safety features will also automatically turn the vape off when the voltage is too low. If either of these happen, then it’s time for a new battery in your device.

Other issues with vape batteries

These issues are more serious and indicate you should change your battery immediately to avoid harm to yourself or others.

Leakage

If there’s a low-quality or incompatible battery in your vape, this can cause the battery to leak fluid. Leakage can also happen if the vape if dropped accidentally and the battery is damaged.

If your battery is leaking, stop using the vape immediately and get the battery replaced. Ignoring the issue is dangerous and can cause the vape to seriously malfunction.

Rattling

Dents or punctures to a vape battery can loosen it from its place in the vape and cause rattling. A rattle is a sound that the batteries make inside the device when they’re not making a proper connection.

If you're experiencing a rattle in your vape and you've ruled out other possible causes, it's likely time to replace the batteries or the device.

Swelling

Swelling occurs when the internal chemistry of the battery causes it to expand, which can put pressure on the exterior of the battery and cause it to bulge or puff out.

It can happen if the vape is repeatedly exposed to high temperatures, used for a long time, or overcharged. If you notice the battery swelling, immediately stop using your vape and get the battery replaced.

Overheating

If your vape is hot to the touch, then the battery may be overheating. If the internal temperature of a vape is too warm, this quickly damages the battery. This can be caused by overcharging or low-quality batteries.

Some devices may have a built-in temperature control feature that will automatically turn off the device when the temperature becomes too high, which can help to prevent overheating. If it’s happening repeatedly, change the battery.

How to replace a vape battery

If you’ve got any of the above issues, don’t worry. Replacing your vape battery is a simple process with only a few steps. It's important to use high-quality, compatible batteries that are specifically designed for mod devices to ensure optimal performance and safety.

Most devices have a compartment on the bottom or side where the batteries are located. This compartment can usually be opened by twisting or pressing a latch. Carefully remove the battery from the compartment.

Place the new battery inside, making sure the positive and negative terminals match. Securely close the compartment and turn on your device to check it’s working properly.
