Good to know about rechargeable batteries

The Battery:
All batteries we sell are pre-charged and ready for use.
Once a battery reaches 3.2V for some mods, 3.4V for others, the mod will give you a warning that the battery is running low or switch itself off.
A fully charged battery gives a reading of 4.1V – 4.2V

As the batteries come pre-charged we advice you not to charge the batteries on arrival, but use them until they are drained.
When the batteries are on the charger, don’t leave the batteries un-attended (EG don’t leave the house whilst the batteries are still in the charger), and don’t leave the batteries on the charger longer than needed.

Battery Unit
All eGo Style batteries have rechargeable Li-Ion batteries, whether it’s internal, or removable
The battery is needed to power the atomiser.

The Battery unit, has a computer chip and a little silicone flap connected to the contacts that activate it.
The computer chip also shuts down the battery if you have taken a draw longer than (With most, though there are other variations as well) 10 seconds or if the voltage is low and it needs recharging.

The Voltage (how much power is delivered to the atomiser): Most e-cig batteries are 3.2-3.7 V. Some mods are 5V or 6V.

The mAh (milliampere hours): This refers to how many puffs you can take before the battery needs to be recharged. Slender batteries (like cig-a-likes) range from 90 to 280 mAh.
Again, the mAh determines how long it will last in-between charges.

The switch (how the battery is engaged): Most e-cig batteries originally had an automatic switch (turned on by sucking on the mouthpiece or by sound or movement) as in a lot of cig-a-likes, also known as pen style.
Now, most batteries are manual (turned on by pressing a button on the side of the battery)
The most popular ones are the eGo style batteries.

The manual batteries, which contain a small button you press during a draw, tend to have less problems than the automatics, but prohibit hands free operation.
They are very popular because you can take as long a draw as you like, and are less likely to malfunction as the connection end of the battery has a closed hole, so e-liquid cannot get into the battery.

The automatic battery (cig-a-like/ pen style) , has an open hole in the connection end, so there is a chance e-liquid can get into the battery.
For this reason, it is very important to keep all connections dry on any battery.
If the battery (automatic) is malfunctioning, take your atomizer/ cartomiser/ clearomiser off the battery and try blowing into the end of the battery with your mouth.
Tap it on the table a few times lightly to dislodge any fluid that might be impeding the contacts.
Wipe it clean and try to vape again.
This is one of the most common trouble-shooting techniques.
It fixes the issue most of the time. If the battery is wet with e-liquid or has dried e-liquid on the connection, it won’t charge. (We do not sell cig-a-likes, please read about Vaper Train to find out why)

A lot of chargers have an LED light that is supposed to tell you when it is charged, but they are not always reliable (other varieties are ones where the light flashes when charged, or there is no LED light at all).
We suggest you charge the battery for at least 3 hours when it is dead, regardless of the light, this way you will get the most out of your battery.
All eGo style batteries come already charged.
You will need to vape your battery entirely dead on this initial charge before you put it on the charger for the first time.
Once the battery is completely drained, put the battery on the charger for roughly 3 hours or until the light turns from red to green.(Depending on your charger)

How long the battery lasts before it needs charging again depends on which unit you have, and the mAh of your battery

The eGo style and 510 batteries have the same 510 connection threads, which allows for the use of a variety of different atomisers/ cartomisers/ clearomisers.
For example: the very popular eGo battery has a wider much higher capacity of battery life with 650, 900, or 1100 mAh. The diameter is about the same as a AA battery.
Also we stock the eGo USB Passthrough where you can vape straight from your PC or USB port while it is charging!!

Li-Ion Battery
Sony commercialised the first Li‑ion battery, and today this chemistry has become the most promising and fastest growing on the market.
Meanwhile, research continues to develop a safe metallic lithium battery.

Lithium is the lightest of all metals, has the greatest electro-chemical potential and provides the largest specific energy per weight.
Rechargeable batteries with lithium metal on the anode (negative electrodes)* could provide extraordinary high energy densities.

The specific energy of Li‑ion is twice that of NiCd, and the high nominal cell voltage of 3.60V as compared to 1.20V for nickel systems contributes to this gain.
Improvements in the active materials of the electrode have the potential of further increases in energy density.
The load characteristics are good, and the flat discharge curve offers effective utilization of the stored energy in a desirable voltage spectrum of 3.70 to 2.80V/cell.

Cost reduction, increase in specific energy and the absence of toxic material paved the road to make Li-ion the universally accepted battery for portable application, first in the consumer industry and now increasingly also in heavy industry, including electric power trains and for vehicles.

Li-ion is a low-maintenance battery, an advantage, many other chemistries can not claim.
The battery has no memory and does not need exercising (deliberate full discharge) to keep in shape.
Self-discharge is less than half that of nickel-based systems.
This makes Li‑ion well suited for fuel gauge applications.
The nominal cell voltage of 3.60V can directly power cell phones and digital cameras, offering simplifications and cost reductions over multi-cell designs.
The drawbacks are the need for protection circuits to prevent abuse, as well as high price.


  • High energy density Relatively low self-discharge; less than half that of NiCd and NiMH
  • Low maintenance.
  • No periodic discharge is needed; no memory.


  • Do not over-discharge/ overcharge
  • Recharge empty batteries ( resting voltage below 3.6V ) as soon as possible. Leaving Li-Ion batteries in discharged state will incur irreversible damage ( capacity /cycle loss );
  • Do not short circuit ( will release tremendous current );
  • Do not dispose of in fire.
