Using the Right Charger
The number one cause of problems with electronic cigarettes is using the wrong charger.
Buy from a Reputable Supplier
Dodgy e-cigarette batteries are brought into the country and are generally sold on markets and by sole traders.
But batteries and chargers are not something you want to skimp on. Overcharge and over-discharge protection, ROHS certification and external battery testing all cost money, so it's well worth being wary of cheap batteries and chargers.
Avoid Heat, Cold and Direct Sunlight
Extreme heat can lead to the resin in batteries melting and deforming, leading to electrolyte leakage and explosion. Avoiding storing your e-cig battery next to radiators/boilers or in direct sunlight.
Avoid Contact with Water
If your battery falls into or gets saturated with water, cease use. Either return it to the supplier or take it to a recycling station.
If you have a damaged battery, dispose of it correctly. If you're not sure how, search for a hazardous waste disposal service near you.
The same goes for damaged batteries – it's just not worth the risk!
Avoid Carrying with Metal
Do not carry in a pocket with coins or keys.
Clean your Battery
The fire service recommends cleaning your e-cigarette battery weekly.
If you can't manage that, do check your battery every now and again to see if any dirt or gunk has accumulated on your battery connection point. Use an alcohol wipe, cotton bud or tissue to gently clean gunk off.
Travelling with your Battery
Most airlines require you to place your battery in your cabin luggage. Before putting your ecig away, make sure you turn it off by pressing the button five times.
If you have a device with a removable battery, most airlines recommend this should be installed in your device before being checked into hold luggage. Ideally, you would also tape over contact points with insulation tape.
Charging your e-cigarette abroad can prove tricky, as voltage supplied by power networks varies from country to country. The best option for charging your battery is to use the charger and plug recommended by your supplier, but with a plug adaptor bought in the country you are visiting. You can also check power supply before visiting a country on this Wikipedia page.
Ideally, you would also use surge protection, although in practice it's not always practical to carry around a surge protection device.
