Battery Safety and Charging Guide

Please read this information to ensure that you correctly and safely use your e-cigarette battery. 


There are different types of e-cigarette batteries and you must ensure that you use the correct charger for each type. 

All VapeHit electronic cigarette batteries must be charged using ONLY the correct charging cable/jack. The VapeHit USB Charging Cable/Jack (output 4.2v) must ONLY be used in either a USB port on a PC, or with the VapeHit UK USB mains wall charger. Larger batteries will take longer to charge due to the increased battery capacity.

For EGO type batteries

We have two main types of USB chargers:

EGO Chargers

1. Charging Cable: This is a standard USB charger and includes a wired section which sits between the EGO battery connector and the USB connector. For use with all EGO type batteries.

2. Charging JackThis is a mini USB charger and excludes the wired sections. This model is for use with standard EGO type batteries and is NOT to be used with an EGO battery which features variable voltage (such as the EGO-C Twist or the Evod Twist).

Charging Process EGO

The LED signal on the battery will flash several times once connected and the LED signal on the charger will illuminate RED indicating the battery is charging. Once the battery is fully charged the LED signal on the charger will switch from RED to GREEN. In some instances before the battery is fully charged the charger may switch to trickle charge mode signalled by the LED pulsing back and forth from RED to GREEN, the battery is virtually fully charged at this point and can be disconnected. Charging most batteries should take between 2 - 4 hours for a full charge.

It is generally advised that you only charge your battery once it is completely run down however newer evidence shows that with lithium batteries they should not be allowed to fully run down, preventing your battery from fully discharging will prolong your battery life and be more safer to use.

The light on the battery will flash to indicate the battery is flat and requires recharging. With some models such as the EGO-V510 battery the battery LED button will signal a different colour indicating the remaining charge level (blue=high, green=med, red=low).

LED charging signal EGO

Micro USB chargeable batteries

These types of batteries will have a Micro USB port on the battery from which you will connect a standard Micro USB charging cable to re-charge the battery. You can connect the Micro USB charging cable to a suitable USB port on your PC to re-charge the battery or connect directly from the mains supply using a USB mains wall charger. The battery LED or OLED will signal when the battery is charged, in all instances please refer to products manual for further information. 

Charging via Micro USB port

IMR / ICR / 18650 battery cells

Some devices will have removeable battery cell type, these are commonly in the size 18650 but some devices may have other dimensions depending on the design of the battery model. These are high powered high drain battery cells commonly used in high powered battery devices to achieve higher wattages when vaping.

With most battery models (not all) they will have a Micro USB port from which you can use a standard Micro USB charging cable to re-charge the inner battery cell. However the most preferred method to safely charge these types of batteries is by using a dedicated charging bay. You may have extra battery cells spares so these types of charger will have bays ranging from 1 to 4 depending on the model you prefer to choose for you use. These battery cells have a positive (+) and a negative (-) end please do ensure to correctly insert the appropriate end into the charging bay which are generally marked with the + or - sign to guide you.  In all instances please refer to products manual for further information on safely charging your device.

Battery Safety

Lithium Ion batteries are safely used in literally millions of devices every day. However there are some risks associated with such high energy devices that users should be aware of. Batteries can present a fire risk when short-circuited, over-charged, submerged in water or if their cases are damaged. Although many Lithium Ion batteries are “protected”, the following cautions are still relevant, as the protection circuit is a potential safety mechanism rather than something that should be relied on. Li-Mn batteries (“IMR”) present safer chemistry and less fire-risk, but are capable of delivering very high power in a short burst. If short-circuited the metal causing the short can get hot very quickly, which may lead to other damage or secondary fire-risks.

  • Store batteries and chargers in a cool, dry place at normal room temperature.

  • Check that the product or packaging displays the correct CE and ROHS safety markings and that the distributor can prove their authenticity.
  • Only use charging equipment in good condition and specific to your battery type.
  • Never mix batteries from one manufacturer with a charger from another without specific confirmation of compatibility.
  • Always charge batteries specifically as directed in the product instruction manual.
  • Transport loose batteries properly separated in non-conductive (e.g. plastic) containers, and never where they can come into contact with metal items that can cause a short circuit (e.g. pockets full of loose change or keys).
