Battery Cells

These are the batteries designed for the external battery vape mods. With external batteries there are 2 things you need to pay attention to when deciding on what suits you best: mAh (Battery capacity) & Amp (How much current the battery can provide).

About vape batteries

Batteries are one of the most important parts of your vape kit because they provide power to your device. Most vape mods that use external batteries require single or dual 18650 batteries. 

How batteries work in a vape

Batteries convert chemical energy into electrical energy. When you vape, the electrical current from the battery moves through the circuit board of the box mod and to the coils, heating them. The hot coils cause the e-liquid saturated in the wicking materials to heat up and turn into the vapour that you breathe in through the drip tip. 

Battery chargers

External vape batteries need to be charged using a charger such as the Li-ion chargers by Xtar. With options for two or four bays, these chargers can have additional features like intelligent battery detection for even better charging.

Types of vape batteries

Batteries for vaping are usually named for their size. The most common external vape batteries at the moment are 18650 batteries - the first two digits (18) refer to the width of the batteries in mm while the remaining three (650) describe the height. 

Struggling to get your head around the different battery types - 18350, 20700, 21700? Just remember that the larger the battery, the more powerful it is. 

At Oxford Vapours, we stock Molicel batteries including the Molicel P26A 2600mAh 25 Amp 18650, the Molicel P42A 4200mAh 30 Amp 21700, and the P28A 2800mAh 25 Amp 18650. Made of high quality and safe materials, these are our go-to batteries for vaping. 

Frequently asked questions

What do mAh and Amp mean?

These are measures of capacity and current handling, the two key characteristics that define batteries. 

Capacity, which is measured in mAh, refers to how long it takes for a battery to go from fully charged to fully discharged. For example, a 3000mAh battery can run 3 amps for an hour before it is fully discharged. 

Current handling is measured in Amps and describes how much electrical current a battery can output at once. 

Current and capacity are closely related: the higher capacity in mAh, the lower Amperage a battery has. In reverse, a low mAh capacity relates to a higher Amp rating. 

When it comes to choosing a battery for your box mod, a lower wattage device is suited to a battery with lower Amp and higher mAh. In contrast, high wattage devices are best used with higher Amp and lower mAh.

What's the difference between single and dual battery mods?

Mods with two batteries instead of one can use more power for longer, making them better for high-power sub-ohm vaping. Dual battery mods also tend to be bigger and chunkier than single battery mods because they require more space in the chassis to fit the two batteries. 

How do I use and charge my batteries safely?

Battery safety is vital while vaping and charging. Here's what you need to do:

  • Buy high quality batteries from a trusted source (like Oxford Vapours).

  • Keep your battery dry and away from extreme hot or cold temperatures.

  • Store batteries in a battery case when not in use.

  • Don't use batteries with damaged wraps.

  • Always keep an eye on your batteries when charging them (and don't overcharge because this can damage battery life).

  • Make sure your battery doesn't come into contact with coins, keys, or other conductive materials.

Can I charge my external batteries while still in the mod?

While it's possible to charge the whole mod using a USB cord instead of removing the batteries and charging them separately, we do not recommend doing this. This is because it damages the lifespan of the batteries and takes longer to charge.

How do I know when to replace my vape kit's batteries?

Most rechargeable batteries need to be replaced in the range of 300 to 500 charge cycles or after around 18 months. However, you'll need to replace your vape battery sooner if it is damaged in any way, for example if the battery wrap is damaged and the conductive material is exposed. 

If your battery isn't performing as well in your kit as it used to, this is another sign that it's time to change your battery. 

Should I buy more batteries than my mod needs?

It's not necessary, but we think it's a good idea to buy extra batteries for your mod. With a few spares, you can alternate charging them in the battery charger so your vape never has downtime. A spare battery or two for your mod also means that you'll have backups if your main battery becomes damaged, resulting in a safer vaping experience.

Just be careful to ensure that you never mix the batteries of your vape. For vaping devices which require more than one battery, ‘marry’ or pair your batteries to ensure consistent charges every time.
