E-Cigarettes Battery Kit Discoball Authentic GS Ego II Rechargeable Battery and USB Charging Cable for 510 Thread Vape Pen Nicotine Free (Black+Steel, 2200mAh, 2 PCS)

Bought 2 of these but unfortunately 1 didn't work, no argument from seller and it was refunded, excellent customer communication and service. Will use these again when I need to reorder

Great, work as they should. I originally had one that only charged from the top but the threading eventually rubbed away leaving it useless and not chargeable. These ones are so much better because they have a mirco usb charger in the base, which in my opinion makes for safer charging and also takes the strain off the threads because you're not constantly screwing chargers into them.The batteries last ages, haven't had an issue with these ones, when fully charged the light goes off and stays off.I use them with the GS H2S Dual coil tanks and also recommend these tanks for them as they're well built, have changeable decent enough coils and are cheap, always try and prime the coils if you can though and leave the tank, full of eliquid for at least 5 minutes before taking afew steady and gentle draws, if it tastes slightly off, your coil isn't saturated enough ( assuming the coil isn't a dud ) so leave it for longer to soak through and then the coils last a good amount of time.Also doesn't matter what battery it is, never leave them charging if you can't closely monitor them, this goes for anything, not just ecig batteries. Better safe than sorry.

This is my second pack of two. These have failed to charged after only 4 weeks. I have had no issues previous. But last 2 deliveries, same thing has happened. Not charging . Such a shame I order regularly.

One of the batteries appeared to stop working after a month then started working again. The cause came down to one particular clearomiser that will only work on my old 420ma batteries and not on the new batteries. All the others work fine. Unfortunately I can't tell you which make of clearomiser is affected but these batteries seem fine and I'm planning on buying more.

I have had several "vaping" batteries and all have caused me problems when charging. Sometimes the battery or charger needs cleaned, but recently two which charged from the top using the special charger could not be charged because the seal gave out and the charger would not fit.This battery (I now have two) combines the ease of charging using any of my usb charging cables (of which we all seem to have plenty) or charging via the traditional special charger (personally have given up on this).So no special charger, no worry about seals or cleaning, so what not to like.Battery charges just as quickly via the usb and lasts all day.All in all a great buy.

I have been using these batteries since 2012, and they are the best.In time needs replacing, as things do.But much better than the bulky batteries.

These batteries work well but have bought twice now and the button goes faulty after about 8 months of use.

Bought these 3 months ago only using one battery so far and it's working and charging fine. Hopefully the other one still it's box will work fine 5/5
