About Vaping Batteries


Always follow the device manufacturers guide to replace batteries.

Batteries Explained (A little bit).

As simply as possible, these are the common types of battery and what those numbers and letters mean.

I = The battery is a Lithium Ion Battery Li-Ion

M = Manganese (Mn) is the positive ion for the battery

C = Cobalt (Co) is the positive ion for the battery

N = Nickel “Ni” is the positive Ion in the battery

F = Iron “Fe” is the positive ion in the battery

R = Rechargeable

INR18650 Lithium Ion Nickel 18mm 65mm

IMR18350 Lithium Ion Manganese 18mm 35mm

ICR17500 Lithium Ion Cobalt Round 17mm 50mm

All the batteries supplied by Battery Vape are IMR type. IMR batteries usually can handle up to 8.0C drain, which means the battery can output 8 times the capacity indicated on the label. As an example, an IMR 18650 battery with 2000mAh capacity can handle 8 times 2000 = 16000mah = 16amp


The lower the resistance of the build the more power is drawn from a battery (expressed in Amps). The higher the power draw, the more mAh used in a given cycle (each time you take a puff). A higher milliamp rated battery will provide a longer runtime but runtime is always dependent on the load placed on the battery. A 10a draw will deplete a battery much faster than a 1a draw.


mAh is the capacity rating of the cell.

Voltage is the difference in electrical potential between two points (the + and – ends of the battery) and is commonly expressed as the ‘Nominal’ voltage of the cell (3.7v for Lithium chemistry cells).

Amps is the amount of current.


The best way to ensure that your batteries are charging safely is to always use the manufacturer’s charging cable or dock that came with your vape device. If in doubt consult the support team.


mAh stands for milliamp-hour. For our purposes, it describes the total amount of energy that a battery can deliver over an hour. For example, a battery with a rated capacity of 3000mAh could deliver 3000 milliamperes — or 3 amps — for one hour before it is exhausted. Using Ohm’s Law If you’re using a battery with a different voltage, or a build that may have a higher or lower resistance, then you can calculate the number of base amps being drawn by using an Ohm’s Law calculator. The results will be the drain in amps. In our example, if your device draws 1 amp an hour then you have 3 hours of power before the battery needs charging. To work out how long you have when you are vaping, take the amount of time the device is being used when you take a hit and divide into the time you worked out before battery discharge. EX: 6 seconds per puff divided into 3 hours of charge. 1 hour 3600 seconds = 1800 puffs from one charge. How much you use your device will determine how long it lasts.


Coil resistance is measured in “ohms” that indicates how quickly electricity is able to travel through. The lower the coil resistance, the easier it is for electricity from your battery to travel through the coil. The lower your coil resistance, the quicker the coil heats up and with this, you get more vapour.

What to the different voltages mean for vaping?

The higher the voltage and the lower the resistance, the more vapour. Lower voltage and higher resistance, less vapour. With variable voltage devices, you can select your own power output, with mods you can select your coil resistance, combine the 2 for a personalised vape experience.

Safety Guide

1.0 ohm = 4.2 amp draw

0.9 ohm = 4.6 amp draw

0.8 ohm = 5.2 amp draw

0.7 ohms = 6 amp draw

0.6 ohms = 7 amp draw

0.5 ohms = 8.4 amp draw

0.4 ohms = 10.5 amp draw

0.3 ohms = 14.0 amp draw

0.2 ohms = 21.0 amp draw

0.1 ohms = 42.0 amp draw = over battery specifications

0.0 ohms = dead short = potential for thermal runaway

What is the max continuous discharge current?

Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is defined by the battery manufacturer in order to stop excessive discharge rates and battery damage. If you see 7C on your battery, it means it can be discharged at 7 times that pack’s capacity. Use the Ohm’s law calculator to make sure your device is not pulling more than your battery can safely supply. CDR is far safer as a measurement guideline than the other, the pulse discharge.

The continuous current rating only defines the maximum current you can continuously draw from the battery for each discharge while maintaining battery life and not causing overheating. Any battery can be used at higher current levels than this rating, especially when pulsed as happens when vaping.

Max pulse discharge - the specs
There is no specification standard in the manufacturing industry for pulse discharge due to the many factors that can affect the rate. Using the continuous current rate is widely accepted as far safer.
Which battery is best for vaping?

Simply put a vape battery that is good for one person may not be good for another, it depends on the use and the device.

Unfortunately, batteries can be either high capacity or high current. Battery technology today just cannot provide both of these into one small 18650 battery. If your mod needs a high current rated battery, you have to sacrifice some capacity. If you need high capacity, you’ll have to settle for a lower current rating.

A good place to start would be the middle ground, BV 3000mAh 30Amp battery.

How to achieve longer battery life.
  • Always use the manufacturer recommended charger.
  • After charging, let it cool to room temperature before using it.
  • If a battery wrap becomes damaged, replace it immediately.
  • Important for battery life is that you never let them get below 30%. Not always easy for sure but best practice. That is why spares are always a good idea.
  • Don’t charge a battery that is below 0 degrees. It causes the metal to be plated inside the battery that could result in an internal short circuit or burst.
Battery Vape batteries are better.

The batteries Battery Vape supply are of the very highest quality. They are manufactured and tested to the strictest possible safety standards.

If you need guidance please contact us for help and advice.

Follow these guidlines for safe use
  • Do not use the battery if battery wrapper is damaged.

  • Do not over-discharge or over-charge the batteries.

  • Do not use if battery wrapper is damaged.

  • Do not keep your battery in a pocket, purse, or other receptacle containing metal objects to avoid short-circuit.

  • The battery may explode or catch fire if mistreated, please use appropriate spare battery container when carrying spares.

  • Do not disassemble, puncture, cut, crush, short-circuit, incinerate, or expose to water or fire. High temperatures above 100℃ or 212F can cause product failure.

  • Remove the batteries from the device when not in use.

  • Use the correct battery for your device, if you are unsure please ask our support team before purchase.

  • Do not use the battery mixed with other different make, type, or model batteries

  • Do not leave battery in charger for over 24 hours

  • Store the battery in a cool, dry and well-ventilated area

  • Keep out of the reach of children
    Never use a modified or damaged charger

  • Avoid excessive physical shock or vibration

    *Going outside of these guidelines may invalidate your warranty.

Battery Chargers

With a rechargeable battery, you can make the chemical reactions run in reverse using a battery charger. Charging your battery is the exact opposite of discharging it: where discharging gives out energy, charging takes energy in and stores it by resetting the battery chemicals to how they were before you used the energy inside. You can do this many times but there eventually comes a point where the cells are no longer able to store charge. At that point, you have to recycle them or throw them away. Chargers often receive low priority but that should most definitely not be the case.

Use Your Charger Safely

If batteries are fully charged and you don’t switch off the charger, they have to get rid of the extra energy you’re feeding them. They release this excess energy by heating up and building up pressure inside. Having a decent charger with all the safety cutoffs in place is vital as this overcharging can make the batteries rupture, leak chemicals or gas, and even explode. The best chargers work intelligently, with electronic circuits to sense how much charge is stored in the batteries and then switching off the current or changing to a low trickle charge at the appropriate time. In theory, it’s impossible to overcharge with an intelligent charger.

If you value your battery life and performance then you should also value the charger. Safety and performance are important to Battery Vape, we only supply the safest products so you can enjoy your vaping with complete peace of mind.
