Questions & Answers

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

  • I have been using the LG HG2's for quite a few...

    Posted by Jerry Jean on Jan 11th 2025

    These work really great. I've got pairs that have been charging and working fine for at least 8 years. I never let them get below 1/2 charge and charge them on an Xtar charger. They've just never let me down. And the CUSTOMER SERVICE at Central Vapors ROCKS! Good people here!

  • ok

    Good for double battery mods. Not for single battery mods...!!! Q

  • Great batteries

    Posted by Michelle Carmichael on Jun 27th 2024

    These batteries hold a charge for a long time.

  • New, but are they....?

    Posted by James Peterson on Mar 4th 2024

    My pervious set of batteries that are at least 2 years older than these newest purchased ones hold a charge for longer. Running the same wattage on the same mod, same coils, tank and everything.

  • Great Batteries

    Posted by dugless on Nov 28th 2023

    As advertised. Had to cycle through full charge a couple of times to reach full capacity.

  • Lasts longer than cheap ones

    Posted by John Bradford on Nov 18th 2023

    Made by UPS, haha, seriously good battery

  • GREAT DEPENDABLE BATTERY

    Posted by Mike on Aug 31st 2023

    Let's face it: push button, inhale, repeat... this is what makes a good battery, reliability!! That's all we want! These batteries have lasted me years of hard, rough treatment. I can say w/o a doubt that I have only had to discard batteries because of issues caused by me, I've had only one that I laid to rest due to it losing charge capacity. That was after 4-yrs and I still have one thats not ready to retire yet @ 5-yrs, maybe I used them differently?!? I have to add, that being upset at the batteries for coming only 20% to 50% charged is pure BS!! They are intentionally charged to that level for protection during shipment!! I fully charge any battery powered device I receive BEFORE use!!! Most people can still charge a battery and figure out how to charge one battery while using the other "half charged" one!!! These are great batteries and will survive many, many cycles...Period!!! BTW: You have got to have the fastest shipping I've experienced since this whole "mailing vapes" debacle began!!!

  • Great battery

    Posted by Vicki Halt on Apr 20th 2023

    Full power for about 48 hours.

  • New Batteries not charged

    Posted by Sandra Saunders on Jan 14th 2023

    I recieved my shipment for 2 batteries for my smok vape. These were the first ones I've bought so I did alot of research to make sure I had the right ones. They work perfectly, but they only had 1/4 to 1/3 of a charge. I'm pleased they fit, but very displeased that they're not charged seeing that they are new batteries. MKes me wonder how old they are. I WILL NOT be ordering anything else from you. Thanks but sorry Sandy

  • These are good batteries too these things do work and when they’re new will last awhile too so don’t just doubt it.

    Posted by William Yuhas Jr on Oct 4th 2022

    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.
