Most standard electronic cigarette batteries are turned on and off with a 5 click function (5 clicks within 2 seconds). That means the clicks are quite fast and have to be very deliberate and this is part of their design to stop them being turned on without you realising.
The easiest way to do this is to count one, two, three etc and ensure you click 5 separate times otherwise the battery may not realise you have clicked 5 times.
The battery will let you know it's recognised that you've turned it on by flashing 3 times (the amount of flashes will vary depending on the battery).
The average electronic cigarette battery has a typical lifetime of 300 charges and this lifespan is significantly reduced if batteries are frequently recharged and in constant use.
These lithium-ion e-cig batteries are also very sensitive to environmental conditions due to the micro technology inside them. Possible causes of a dead battery include contact problems, faulty battery, overuse, misuse, damage, environmental conditions and lifespan exceeded.
If you're still stuck, the following options may help, however, depending on the issue you have, it's often better just to get a new battery to be on the safe side.
If you get liquid in the battery it can become stuck in the on or off position rendering it unusable. The LED button often still pushes but liquid can still put it out of working order. You may find though that it starts to work again days later when it's been allowed to dry out. Try tapping the battery gently onto a paper towel if you have excess liquid around the button. Don't directly tap the button and especially not on a hard surface or you may damage it.
Good clean contact between your e-cig battery and tank is essential for the best heat, vapour and flavour, so regular cleaning is essential (every couple of weeks or so for example). Rubbing alcohol/surgical spirit on a Q tip/cotton bud is ideal.
Clean the outside of the connection/contact area and the inside too ensuring that you hold the battery upside down so gravity can take away any excess fluid. Paper towel can be used to dry the area if necessary.
For stubborn grime a cocktail stick is ideal for the threaded grooves, taking care not to break it off inside the battery, but don’t use anything metal.
There are several possible causes including a damaged battery and battery pressure switches sticking which can cause the microchip to jam on. If you can't get it un-stuck, you will need a new battery.
Batteries have a limited life so they won’t last forever. Their lifetimes vary, on average about 300 charge/discharge cycles. However, if the battery is relatively new and it won’t hold its charge it is likely to be faulty or damaged.
Most likely to be related to the contact points between the battery and the atomizer or it could be the atomizer head/coil head. See our page about lack or loss of vapour troubleshooting (click here).
The cut-off point of an e-cig battery can be anything from 5 to 10 seconds depending on the item. This is a standard safety feature in that batteries are designed to cut out in order to prevent overheating.
Certain batteries will flash 3 times to indicate a short circuit. Most standard e-cig batteries will have what's called short circuit protection, so when there is a short and you press the fire button it will just blink 3 times and then won't do anything.
Does it still blink 3 times with no tank? (remove the tank, ensure the battery is turned on and press the fire button to check).
If the LED still flashes 3 times without the tank you know it's something to do with the battery, if it only flashes when it's connected to the tank it could be the that there isn’t a good connection, or it could be the coil.
If the tank is screwed down too hard it can push the centre pin on the battery down just a tad and the connection is lost. Just check the battery isn’t screwed on too tight. Try backing it off a bit and see what happens.
Also try another coil in case that’s the problem, depending on what you’ve already discovered above.
The battery is low and needs to be recharged. Most standard e-cig batteries flash, generally rapidly, in an effort to let you know they're running out of power.
This is common with automatic batteries. One solution is to take the ash end and literally give it a good hard couple of taps on a hard surface.
This can help force the switch mechanism back into its proper position but doesn't always work.
Don't put paperclips or other items inside the battery and don’t use compressed air. This can permanently damage the switch. Also make sure you are not storing your batteries in pockets or other places with a lot of dust.
The type of dust in pockets will get inside the battery and can cause the switch to malfunction. The battery can also occasionally get a small amount of liquid inside it which causes it to malfunction.
Batteries often work fine if you give them time to dry out so put the battery somewhere safe and just allow it to sit for a day or two.
This is a sign the battery has a serious problem. DON'T THROW IT IN THE BIN! Put the battery somewhere to cool down where it doesn't pose a fire risk (a granite work top for example) and do not attempt to use this battery again.
Green is for charged so you don’t need to charge it any more. All batteries come part charged and you should be able to use them straight away without the need for immediate charging.
The battery is near fully charged. It’s just letting you know it’s nearly charged.
The battery is near fully charged. It’s just letting you know it’s nearly charged (the LED on some USB chargers turns blue when charging is complete).
