Best 18650 Batteries for Vaping | What Batteries Should You Buy?

Picking the best 18650 batteries to buy for your vape can be a minefield! In truth, there isn’t any one particular 18650 battery that stands above the rest. Instead, it all depends on how you like to vape…

In a nutshell, you need to know what amps you’ll be drawing from your battery. The amp rating (CDR – Continuous Discharge Rating) is arguably the single most important factor when deciding which 18650 battery is best for you.

The higher the watts you vape at, the higher the CDR you’ll need.

18650 batteries with a lower CDR (and larger mAh capacity) can vape for days without needing a recharge but they may get hot and potentially dangerous at higher watts. In contrast, 18650 batteries with a higher CDR are safe to use at higher watts, but you’ll need to recharge them more frequently.

If you’re confused about what CDR you need, we’ve created calculators for regulated mods and unregulated mods. These will help you work out what amps you’ll be drawing from your battery and what 18650 battery is safe for you to use. 

Read on for a list of the best 18650 batteries for vaping, broken down by their Continuous Discharge Rating.

What type of 18650 battery suits my vaping style?

Best 18650 Batteries

We’ve even gone a little further and split the list into three different styles of vape setup:

  • Higher wattage vape mods (30A+) – If you’re chasing clouds and using a mod with higher variable wattage, the best 18650 batteries to buy are those with a higher CDR (30A+). While there’s no fixed figure for what you can consider higher wattage, we’d consider anything over 50 watts to fall into this category. Just keep in mind, 18650 batteries with a higher CDR come with a lower mAh capacity (battery life).
  • Medium to higher wattage vape mods (20 – 30A) – If you want the best of both worlds, you’ll want an 18650 battery that can safely deliver between 20-30 amps. 18650 batteries within this range also have the benefit of a higher mAh capacity (battery life). We’d consider anything between 20-50 watts to fall into this category.
  • Lower wattage vape mods (up to 20A) – If you’re more interested in vaping at a lower wattage and making each vape battery last, the best 18650 batteries to buy are those with a lower amp rating and higher mAh capacity. Ideal for vaping at anything under 20 watts!

Nominal Voltage – 3.6V
Cut Off Voltage – 2.5V

The batteries in the above list, in our humble opinion, are the best 18650 batteries you can buy for your vaping needs. Now while we warned you about using re-wrapped batteries above, there is an exception to the rule. All of the team here at Vaping Hardware have been using the Efest 18650 batteries for some time now. These batteries aren’t as reliable as the above cells but are still definitely worth a look!

Things to consider before you buy!

If you’re after the best 18650 batteries then the way to go is with a trusted source. When you buy from a big brand name like Sony or Samsung you know exactly what you’re getting and you won’t be compromising on quality.

When you haven’t heard of the brand you’re buying then make sure to do your research! Many of the lesser known brands, especially those based in China, can be unsafe. Many suppliers buy the batteries produced by companies like Sony that didn’t meet the quality testing post production. These companies then re-wrap the substandard batteries with their own sleeve and sell them on claiming to be the best 18650 batteries on the market!

As a rule of thumb you want to try and avoid buying 18650s from companies like Trustfire or Ultrafire. These brands only sell re-wrapped batteries. Unfortunately, this means you can never quite be sure what you’re getting. Not ideal and also potentially hazardous!

If you need some ideas on where to shop for the best 18650 batteries, take a look at the list of trusted suppliers below!

    1. Hello Ado,

      Thanks for your comment! We would really recommend buying either the LG HB battery series or the Sony VTC4…. these are both excellent 18650 batteries for vaping higher wattage devices! As for where you can buy these in Cape Town I’m not so sure. A quick google search shows great reviews for ‘Foggas Vape Shop’ in Cape Town ( so you might want to give them a try. Happy vape shopping 🙂

  1. I personally like the LG brand. I’m not sure if it’s the best performing battery though. There are so many out and I can’t try them all. What would you recommend for battery life vaping at low wattage?

    1. Hi Jason, thanks for your comment. We also love the LG brand 🙂 If you’re vaping at low wattage, we’d recommend taking a look at a battery with high mAh (something in the region of 3000+). It’s worth keeping in mind the higher the mAh, the lower the discharge rate. Therefore, these batteries can’t be used at high wattage. As always, NEVER exceed the CDR (continuous discharge rate) stated on the battery! If in doubt, take a look at our current, power and resistance calculator to make sure your battery is able to safely deliver the current you need. Hope that helps!

    1. Hi Jason,

      Thanks for the comment! We’re really glad you liked the post and we agree that batteries are important (and often overlooked!). Keep you eyes peeled because we’ll be uploading a new battery guide soon!!
