I’ve had one of these for years and started vaping again and it still worked and charges and does what it was made to do I bought one on here and so far it’s been doing what it’s supposed to do so just understand all of these batteries will drain after awhile! Once it’s halfway dead they start actually giving less power so your hits will start to be less cloudy and good the more dead the battery level becomes and that’s with any battery you use.

So far these batteries have lived up to the reviews that I read before I bought them so I figured I should do the same and pass it along! My first hit of the day is 8am and I won’t have to change the batteries for at least 12 hours, usually more. I know everyone vapes at different wattages and could vape more or less than me during that time but I can tell that the very best I got from my previous batteries following my same routine was maybe 7-8 hours. Enjoy!

I purchased two batteries. One held a full charge once. Now neither hold a charge. Looking for replacements from another source.

I have tried all kinds of 18650 batteries- some awesome- some not so great. These LG fall into the awesome category. They last a long time- and keep my blowing clouds throughout the day. Will be back for more of these! Thanks!

I've been using lg hg2 batteries for many years. I typically replace them every year and these ones I got from central vapors do not last as long or hit as hard as even my 1.5 year old batteries. Theres definitely something not right with them. My normal supplier was out of stock so I took the risk and bought somewhere else and got scammed. Do not buy batteries from central vapors.

Central Vapors gave me a GREAT price, quick shipping. However, the batteries I received were manufactured May2019, so they seem a bit dated? The first set that I charged and used have worked OK so far, but the first charge they didn't seem to charge to the 'full' capacity they should have. I did send an email to Central Vapors regarding the date of manufacture, but never received a response.
