QAny tips for using 18650 batteries safely?

Central Vapors Team · Jun 27, 2026

AUse a quality external charger, keep cells in a case (never loose in a pocket with keys or coins), don't use a cell with torn wrap, and in dual-battery mods use a matched, married pair. Replace any battery that's damaged. — Central Vapors

  • All Day Power

    Posted by Harris B. on Aug 20th 2022

    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!

  • Won't hold a charge

    Posted by David Hasley on Jan 20th 2022

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

  • Happy to be able to get batteries

    Happy to be able to purchase and get them

  • Great high drain vape battery

    Posted by Brandy Havers on Nov 28th 2021

    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!

  • Not genuine

    Posted by Nick R. on Nov 10th 2021

    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.

  • LG Batteries are great, but I received older ones

    Posted by Kristen on Nov 6th 2021

    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.

  • Customer service

    Posted by Clinton W. on Oct 21st 2021

    I tried reaching out... Twice. To explain that one of my batteries got really hot to the touch on the first charge.

  • It Works

    Posted by X3M on Oct 6th 2021

    I purchased 10 of these batteries. 5 of them were charged to over 3000 mah the other 5 were just short of 3000 mah which made me question are these genuine HG2's. Other than that they do last a long time but only time will tell.

  • Great cell- for *more* than just vape mods

    Posted by Sean in on Sep 27th 2021

    Not a vape user myself, but can vouch for the power of this cell. Maybe one or two are used for vape mods, this cell was a perfect fit to make a new battery back for my evolve electric skateboard. 'LHB' built and installed the battery for my evolve carbon GT esk8. Went from a tired and sad old battery pack to one that triples my range (now 15-20 miles) using 40 of these cells. Fast shipping, excellent service. Highly recommend! Cheers

  • Great customer service and products

    Posted by Laura Ann Bienvenue on Sep 9th 2021

    I was concerned about the batteries charging since they were so low in charge when I received them. However once they got a full charge, they held it. I'm very pleased.
