Battery Safety

General Battery Safety and Advice

All of the batteries used in our electronic cigarettes are Lithium-ion.

Lithium-ion cells must be used safely and sensibly. They are very sensitive to charging characteristics and could burn, and on some rare occasions, vent, if handled incorrectly.

We have created some DOs and DON’T’s for you to follow:

  • DO Always charge in or on a fire-proof surface.
  • DO always use the correct charger for your device. Use of third party chargers and adapters is not advised.
  • DO remove your atomiser and disconnect the battery if your e-cigarette or device begins activating by itself, immediately. DO NOT use the battery, nor the atomiser from this point on and DO NOT leave either of the components connected in your pocket, in your nightstand, or out of visibility where you can not immediately separate the two components.
  • DO ensure you always use the charger that is specified for your device. Using the wrong charger, or a charger supplied by a third-party, may risk causing damage to the battery.
  • DO keep batteries out of reach of children or pets, at all times.
  • DO NOT leave charging batteries unattended.
  • DO NOT leave batteries to charge overnight.
  • DO NOT continue to use an e-cigarette type device if you feel the battery become hot. If your battery becomes hot to the touch, or if it begins to smell, CEASE USING IT IMMEDIATELY. Let it cool down (for at least 1 hour) in a safe environment, preferably outside on a fire-proof surface. When it has cooled completely, dispose of it correctly, or make arrangements to return the unit if it is still under warranty.

And please note: JAC VAPOUR LTD cannot be held responsible for damage if there is any modification of the batteries/chargers in any shape or form (including pack making). We are not responsible for any damage caused by misuse or mishandling of Lithium-Ion batteries and chargers. We will not be held responsible or liable for any injury, damage, or defect, permanent or temporary that may be caused by the use of any batteries.


Storing Lithium-ion Batteries

If you know that your battery will not be used for short periods, it is safe to store it with a tank or cart still attached. Should you choose to do so, you should first make sure that you’ve checked and cleaned the batteries thoroughly, and store your e-cig upright and securely.

Ensure that the device is stored safely, and in a place where it is not in danger of being knocked or damaged.

If your battery is likely to be unused for a significant period of time, you should remove any tank or cartomiser and store these separately.

When storing a device for long durations, be aware that the internal cell will naturally deplete over time. Batteries should be stored after being charged, and it’s advisable to periodically top-off the charge and test the battery to ensure that it is still functioning correctly. Cells which are allowed to deplete entirely are unlikely to still accept a charge when you come to use them again.


IMR Batteries

IMR batteries use a safe lithium-manganese chemistry, that offers greater stability than alternative types of cell chemistry.

When working with loose IMR cells, it’s essential that they are kept separate and apart from any other metal objects. Do not keep your batteries loose in a pocket, bag or any other environment where they may touch other metal items such as keys.

IMR batteries are suitable for use in a range of devices, from Variable Wattage box mods, to mechanical pipe mods. It’s essential, however, to ensure that you are using the correct battery in your device. This involves checking you have the correct size of cell (18350, 18650 etc), and that you are aware of the safe amp limit of said battery.

Most Variable Wattage devices are fitted with protective mechanisms to prevent the amp limit of your battery from being exceeded, but mechanical mods do not offer this same protection. When using an unregulated mod, you must first establish what the safe amp limit of your battery is, and do not exceed this.

The amps being drawn from a battery can be calculated by dividing the voltage at which it operates, by the resistance of the coil being used. For example, if you are using a freshly charged IMR18650 battery (which will start with 4.2v of power), with a tank fitted with a 1.5Ohm coil, you will be drawing 2.8Amps. As long as your battery has a continuous amp limit of more than this (ideally with plenty of headroom on top), it will be safe to use.

Storing IMR Batteries

When storing your IMR batteries, it’s important to always remove them from the device you are using.

Loose IMR cells should be stored away from any other metal objects, ideally in a protective case. Never store multiple loose cells together, other than in a suitable protective case.

IMR batteries are also subject to depletion over time. Cells which are allowed to deplete entirely are unlikely to still accept a charge when you come to use them again.
