Ever wondered what the best 18650 batteries for vaping are? Picking an 18650 battery to buy for your vape can be a complete minefield! In truth, there isn’t really any one particular battery that stands above the rest. Really, it all depends on how you like to vape. Before you decide which 18650 battery to buy you really need to know what kind of setup you’re going to be using it with.

Some 18650 batteries have high mAh ratings (battery capacity). Others let you vape safely with higher discharge rates; 30A or above (typically at the expense of the battery life). Simply put, while some 18650 batteries can vape for days without requiring a recharge, they may get hot and potentially dangerous to use in higher wattage devices. Alternatively, some 18650 batteries won’t get hot at higher discharge rates (30A or above), but you’ll be recharging them more frequently.

So how do you pick the best 18650 batteries for your vape?

Best 18650 Batteries

To make things a little easier on you we’ve compiled a list below of the best 18650 batteries to buy, across the following three vape setups:

  • Higher wattage devices (30A and higher) – Ideal battery has a higher amp rating, usually at the expense of battery life.
  • Medium to higher wattage devices (20 – 30A) – Ideal battery still maintains a fairly high amp rating but holds increased battery capacity.
  • Lower wattage devices (up to 20A) – Ideal battery has a lower amp rating with an extended battery life.

But first…

Things to consider before you buy!

Always make sure that you’re buying 18650 batteries from a trusted source. If you’re buying a big brand name like Sony or Samsung from a reputable source, you should be fine.

If you haven’t heard of the brand you’re buying then 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…occasionally at an even higher price!

As a rule of thumb you want to try and avoid buying 18650 batteries 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 your 18650 batteries we’ve included a trusted suppliers list at the bottom of this page.

Best 18650 Batteries – Higher Wattage Devices (30A and higher)

1) LG HB2 / HB4 / HB6 – With a maximum continuous discharge rate of 30A and a battery capacity of 1500 mAh these range of 18650 batteries from LG are perfect for heavy duty sub-ohm vaping. The three different models are all basically the same battery, with each just being a different generation of the HB series.

There are only very slight differences between the three but if you really want the absolute best for your higher wattage device then go for the HB6. It runs at a slightly cooler internal temperature and has slightly more capacity and voltage at the higher current levels.

Price – $5/£3.70
Discharge Current – 30A
Battery Capacity – 1500 mAh
Nominal Voltage – 3.6V
Charging Voltage – 4.2V
Cut Off Voltage – 2.5V

2) Sony VTC4 – Another great 18650 battery for higher wattage devices; the VTC4 from Sony has an impressive 2100 mAh battery capacity and a continuous discharge rate of 30A. If you’re looking for an 18650 for your higher wattage device, you wouldn’t go far wrong with the Sony VTC4.

Price – $5/£3.70
Discharge Current – 30A
Battery Capacity – 2100 mAh
Nominal Voltage – 3.6V

Best 18650 Batteries – Medium to Higher Wattage Devices (20 – 30A)

1) LG HD2 – With a 25A rating and a 2000 mAh battery capacity, the HD2 from LG serves as a brilliant all round 18650 battery. While it has an impressive amp rating the battery capacity also remains fairly high.

Price – $7/£6.99
Discharge Current – 25A
Battery Capacity – 2000 mAh
Nominal Voltage – 3.6V

2) LG HG2 – Another great 18650 battery from LG; the HG2 holds a very impressive 3000 mAh battery capacity while still maintaining a very reasonable 20A rating.

Price – $9.95/£7.30
Discharge Rate – 20A
Battery Capacity – 3000 mAh
Nominal Voltage – 3.7V
Cut Off Voltage – 2.5V

3) Samsung 25R – Samsung’s first entry in the list sees a battery with a 2500 mAh capacity and a guaranteed 20A continuous current supply. An even more compelling reason to choose the Samsung 25R is their incredibly long life.  According to Samsung these batteries will survive over 250 recharging cycles!

Price – $8.80/£6.50
Discharge Rate – 20A
Battery Capacity – 2500 mAh
Nominal Voltage – 3.6V
Cut Off Voltage – 2.5V

4) LG HE2/HE4 – LG certainly know how to produce a great 18650 battery and the HE2/HE4s are no different! With a very respectable capacity of 2500 mAh and a continuous max discharge current of 20A, these batteries will do a stand up job in any medium – high wattage device.

The difference between the two models isn’t much…mainly improved heat control with the later released HE4.

Price – $9.50/£7
Discharge Rate – 20A
Battery Capacity – 2500 mAh
Nominal Voltage – 3.6V
Cut Off Voltage – 2.5V

Best 18650 Batteries – Lower Wattage Devices (up to 20A)

1) Panasonic/Sanyo NCR18650GA – With a whopping capacity of 3500 mAh this fantastic cell with go for days in a lower wattage device. With a 10A max continuous discharge rate you should only use this device in the lower end range.

Price – $6.30/£4.70
Discharge Rate – 10A
Battery Capacity – 3500 mAh
Nominal Voltage – 3.6V
Cut Off Voltage – 2.5V

2) Samsung 30Q – This fantastic cell from Samsung features a capacity of 3000 mAh and a continous discharge rate of 15A. While tests indicate that this 18650 battery performs reasonably well at 20A, for safety its best to stick at the 15A mark.

Price – $10/£7.50
Discharge Rate – 20A (recommended 15A)
Battery Capacity – 3000 mAh
Nominal Voltage – 3.6V
Cut Off Voltage – 2.5V

3) Sony VTC6 – This little green cell holds a battery life of 3000 mAh and a recommended discharge rate of 15A. Tests have shown that the battery can manage 20A discharge but as with the above Samsung cell, its safer to stick to the recommended discharge rate.

Price – $10.80/£8
Discharge Rate – 15A
Battery Capacity – 3000 mAh
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!

In terms of taking care of your batteries and making sure you use them safely once they turn up, be sure to take a peek at our Battery Safety Guide.

    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!!

  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. 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 (https://foggasvapeshop.co.za/) so you might want to give them a try. Happy vape shopping 🙂
