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.

sinowatt 3000mah 18650's (19 January 2024)

good solid performer of a battery, keeps you entertained all day no bother., with power left to spare if your lucky, no complaints to report at this time. (don't worry if you've never heard of these before, i have).

charges smooth and even, just like any other type of cell on the market, as long as you've got a reputable battery charger obviously, no overheating issues anywhere neither.

attractive price for the pair, not bad all round, i purchased a pair at that brown price, you really can't go wrong?.

great, hassle free next day delivery too. 10 stars........

Fantastic (03 November 2023)

I got these as my old ones had started to give up the ghost and I couldn't be happier, the last a good amount of time, charge well, drain equally and at this price are well worth it, I bought 2 extra sets after getting my first one. I've tried brand name batteries such as Samsung and I find these to be at least as good if not better and for half the price, I'd recommend to anyone

By Rammie from Norfolk

Battery (02 October 2023)

By Kopinksi

It does the job (29 August 2023)

A good battery with longevity. I'm pleased with it.

Great product (01 August 2023)

Great battery. Lasts most of the day. Happy with it

By Sunny from Cornwall

Nice (12 June 2023)

These are good, charge well and last me a day of constant use.

By Asif from Cardiff

Good battery (29 May 2023)

Nothing to complain about. Battery last long and price is cheap. 10 stars from me.


Best I've ever used (24 May 2023)

These batteries are without doubt the best I've ever used. Head & tails above Molicell or Sony.

I've had them all over tye years & Sinowatt hold their charge all the way to the end. Whereas nearly all others get weak at about 3/4 used.

Fantastic batteries that out perform all others, was amazed myself. Buy some or just one & you'll see.

SINOWATT 30SP (18 May 2023)

Nice battery backup. Price is cheap and works very well. Also fast charging time.

By Sam M from London

Does the job at a great price. (10 May 2023)

As the title says, does the job at a great price.

They charge very well in my smok kit, but also very well in my battery charger.

Have been using them for a while and haven't seen any degradation in their abilty.

Would highly recommend.

By Steff107 from Gloucestershire

Brilliant (14 April 2023)

Great batteries. Power my device well, lasts me all day.

By Salah from Bradford

So far so good (01 April 2023)

This is my first time using a vape kit with such a battery the charge holding is good and the idea of having a vape with a replicable battery sound nice.

By TeaLady from Liverpool

Good batteries (20 March 2023)

Good batteries, charge quickly and power my device well.

By YogiB from Cambridge

Pretty good so far. (17 March 2023)

I'm using these batteries in my smok x-priv. I have 2 tanks. I vape a lot. They're out lasting the batteries I bought off amazon so it's a big thumbs uo! Would reccomend!

By Graeme from Aberdeen

30SP 18650 BATTERY (17 July 2022)

I'd never heard of this make of battery. It's always a trade off between current and capacity, but thought they'd be good in my middle range of tank. I ran them at 55w and they lasted a day. Definitely a good buy under those circumstances
