Disclaimer On Use Of Batteries


Batteries must:

  • Be charged correctly: The current and voltage used to charge the batteries must not be greater than is set out in the instructions. Batteries should not be charged in excessively cold or hot temperatures. Do not leave the battery in the charger for over 24 hours. Do not leave the battery unattended whilst charging. Never use a modified or damaged charge.
  • Use the correct discharge current: The discharging current shouldn't exceed the level set out in the instructions. If it does this may cause the battery to overheat.
  • Store the batteries at the right temperature: batteries should be stored at an ambient temperature in dry, well-ventilated conditions. You should avoid excessive hot or cold.
  • Keep your batteries in a case when not in use. Don't carry them around loose in bags or pockets: It's vitally important that batteries do not come into contact with any metal objects as this can lead to leakage, explosion or fire.
  • Not be used if they are damaged, abnormally hot, discoloured, deformed, if the wrapping is not intact or if any other abnormal conditions are detected. Dispose of the batteries if this occurs.
  • Not be allowed to come into contact with water or fire. Dispose of the batteries if this occurs.
  • Not be put in microwave ovens or in any high pressure container.
  • Not be used or assembled with other different makes, types or models of batteries.
  • Avoid excessive physical shock or vibration.

If liquid leaking from a battery gets in your eyes, don't rub your eyes, wash them with clean water and seek medical attention immediately. Ensure that the battery is disposed of immediately and that any liquid that has leaked from the battery is contained and removed as it may cause explosion or fire.

Each country has its own rules on the disposal of batteries. Please ensure that you dispose of the batteries in accordance with local regulations.

Fantastic buy (15 February 2024)

Easily the best batteries I have used, last about 3 times as long as my old molicel ones

By Owen

feel the powaahhh (27 January 2024)

these generate perfect power for my device. cannot fault them!

By Will from Wales

The rave is real (23 January 2024)

These are absolutely brilliant batteries. I got them as per the recommendation by the god Mooch. These things last for ages, don't get hot, and are overall very well-built, sturdy batteries.

At £10 a battery they are fairly steep (IMO), but they're well worth it -- even at £20, you'll get a lot of value out of these batteries.

By Bell from Scotland

Great battery (08 August 2023)

great batteries and a good price. charge to the full amount last me a few days but i dont vape as heavy as i used to. good product will buy more of them

By Anne Marie from Gloucester

All day long (20 July 2023)

Only need to use one of these a day, I'm not a heavy vaper but I have my moments! One of these little powerhouses will last a whole day for me when charged on a decent charger . I use a snowwolf mini 100 Watts mod with a freemax Mpro 2 tank at 40 Watts and one battery lasts me all day , I change my battery right before I go to bed and switch my vape off ready for morning.

By Portech from Wales

Great batteries and service (09 June 2023)

Ordered a few if these for my Geekvape L200 classic and they last all day vaping at 75w with a dual coil RTA.
Awesome 👌

Shout out to the Vapeclub team also, Uber fast delivery and excellent service 👍

By Moanyvaper from Hertfordshire

Great batteries (21 May 2023)

Been using this for a couple of months before leaving this review, great batteries, hold up well and are consistent, no loss of power or time they last yet, i vape at around 60/68w so this doesn’t last a day in a single battery mod if you vape heavy, i have 2 batteries so not an issue. I would highly recommend, but they are known to be one of the best batteries for vaping!!
Great service from vapeclub as always!

Bought for a Thallo S (24 February 2023)

Great battery, charges fast, holds it's charge. Lasts all day and I vape from sun up to sun down! 10/10 Great 21700 for a Thallo S

By Shakey from Birmingham

Finally a battery that lasts all day and more :) (24 January 2023)

I was finding a single 18650 battery were not lasting and I seemed to be charging them frequently. After researching and finding the Molicel 21700 4200 mAh I made the best decision to convert and purchased a Geekvape Aegis Max100 mod with it. I vape at around 40 watts and they last all day plus I'm still using at least 30% the next day! I would highly recommend these batteries with superfast delivery and I will be purchasing more vape products from Vape Club UK in the future.

The one and only! (18 December 2022)

These are the only batteries I use. The Molicell 21700 lasts easily a day while vaping quite heavily at 80W. I would reccomend getting 2 with a good charger, so you always have one charged and ready to go.
Highly recommend!

By Luke from West Sussex

Battery of the century (09 October 2022)

By Alfie from Essex

Long lasting (08 October 2022)

Battery lasts a lot longer than my old 18650 battery definitely a justified purchase, I recommend.

By Chunkie from At Home

Excellent Battery (22 September 2022)

Excellent Battery
It's a molicel so you can't go wrong.
Good price and good quality.
Performs extremely well
One of the best battery's you can get

By Lize from UK

Seem OK (31 July 2022)

Got these to use in single battery DNA75C. Running around mid 50W mark then I need 2 batteries to last a day, probably around 4 to 500 hits per battery.

By MG from Manchester

Battery (30 July 2022)

These batteries last alot longer then expected would definitely recommend :-))))

By Kes from Manchester

Watch the end caps (29 June 2022)

The only 21700 cells I'll buy. Just a note, though, if you're having to rewrap them you might want to get new end caps first, the ones already there can go flying mid-wrap very easily.

By GA88 from UK

It's amazing! (23 June 2022)

It lasts much longer than a 3000mAh battery, best I have ever had. Love it!

By Amber

Really Good Battery (15 June 2022)

Have only ever used the 18650 before. Just got a new vape and this battery fits better. It lasts so much longer too!

By Connor from Yorkshire

Fine (03 June 2022)

Does its job, never had any problems with these and life is as expected.

By Joe from Bramford

Great (18 April 2022)
