Vape Battery Safety: Charging & Storing Safely

Temple of Vape Team · July 18, 2026

Vape batteries are safe when treated properly — the rare problems you hear about almost always come down to damage, dodgy chargers or careless storage. A few simple habits keep you and your device safe.

Charging your vape

  • Use the right charger. Charge with the cable and plug supplied, or a good-quality equivalent. Cheap, unbranded fast chargers can push too much current.

  • Don't leave it charging unattended overnight. Charge when you're around to keep an eye on it, and unplug once it's full.

  • Charge on a hard surface. Not on a bed, sofa or anything that traps heat.

  • Stop if it gets hot. A battery should be warm at most. If it's hot, swelling or smells odd, unplug it and stop using it.

Looking after removable batteries

Many bigger kits use removable 18650 (or similar) batteries. These need a little more care:

  • Never carry loose batteries in a pocket or bag with keys or coins — a short circuit across the terminals can make them overheat. Use a plastic battery case.

  • Check the wrap. If the plastic sleeve around the battery is torn or damaged, retire the battery — a nicked wrap can cause a short.

  • Charge them in a proper external charger designed for that battery type where possible.

Storing your device

Keep batteries and devices out of direct sunlight and away from heat — never leave your vape on a car dashboard on a warm day. Extreme cold isn't great either. A drawer or bag at room temperature is ideal. If you're storing a device for a while, leave it around half-charged rather than flat or full.

Everyday habits that help

Turn your device off when it's in a pocket or bag so the fire button can't be pressed accidentally — this also stops the battery draining and overheating. This is the same habit that keeps you safe when travelling with a vape, where batteries must go in your hand luggage.

When to replace a battery

Batteries don't last forever. If yours drains far quicker than it used to, gets warm in normal use, or the device won't hold charge, it's time for a new battery or kit. Don't try to squeeze life out of a damaged one.

Treat your batteries with a bit of respect and they'll serve you safely for a long time — it's mostly common sense.
