Improper handling or misuse of this lithium-ion battery can result in
FIRE, EXPLOSION, or THERMAL RUNAWAY,
causing personal injury, property damage, or death. Users must read and
follow all safety guidelines before purchase and use.

Critical Warning: Never carry loose batteries in your pocket,
purse, or bag. Loose batteries can come into contact with metal objects like
keys or coins, causing a short circuit, which may result in severe burns, fire,
or explosion. Always store or transport batteries in a protective case or box.
Intended Use: This battery is designed for integration into
protected battery packs with a
Battery Management System (BMS) or
Protection Circuit Board (PCB). It is not intended for standalone
use or use in devices such as e-cigarettes or vaporizers.
What is Thermal Runaway?
A dangerous chain reaction where heat generated by a failing battery causes
it to overheat further, potentially leading to fire or explosion.
Causes: Overcharging, short circuits, physical damage, or exposure to high temperatures.
Prevention: Use a smart charger, avoid physical damage, and
store batteries in a cool, dry place.
Storage & Transport: Always store batteries in protective cases
or boxes to prevent accidental contact with metal objects. Never store loose
batteries in pockets, purses, bags, or near conductive materials.
Inspection: Do not use if the PVC wrapper,
terminal insulator, or casing is damaged, dented,
leaking, or bulging. These are signs of internal damage or instability, and
continued use could result in failure, fire, or explosion.
Charging: Use a smart charger designed specifically
for lithium-ion batteries and ensure that the charger's voltage matches the battery's
specifications. Never overcharge, over-discharge, or leave unattended while charging.
Prohibited Activities: Do not short circuit, modify, puncture, crush,
expose to liquids, or solder directly onto the battery (spot weld only).
Emergency Response: If a cell shows signs of thermal runaway (smoke, swelling, hissing, or heat), stop use immediately and, if it can be done safely, move it to a non-flammable surface (e.g., concrete or sand) away from combustibles. Lithium-ion cell fires are Class B fires — use an ABC/dry-chemical extinguisher, or douse with large amounts of water to cool the cell and prevent spread. Do not rely on a small spray; thorough cooling is required, and cells can reignite from residual heat, so monitor the area afterward. (Class D extinguishers are for lithium-metal batteries, not lithium-ion.) For any fire beyond a single small cell, evacuate and call emergency services.

This is the only battery that works in my vapes. It has steady power and no surging. I liked it so much I bought more.
Great batteries for low wattage vapers. I bought three so I could have two fully charged ones in my case and one in my mod. I marked the batteries with one, two and three dots for easy rotation of use. HIGHLY RECCOMENDED!
I bought these and my wife went through several other brands including Samsung. Mine are over 6 years old and are just now notably losing capacity. Best vape battery we ever had.... I'm here to order more since Amazon no longer carries them.
I have been using these specific batteries in my vapes for YEARS, they're the best batteries I have ever used. I rotate batteries and I run 3 vapes all day, every day. These are the only batteries that I get several days out of.
Love these batteries they have a long life span and that saves money in the long run!! My last batch lasted almost 6 years before they stopped holding a charge!
Years ago when I started vaping i got these and have several sets. I've bought other brands but these still keep on trucking. It's been 8 years and I finally needed some more, so of course I had to get the same ones
I've always used MXJO batteries in all of my vape mods. By far the best brand to use. They last all day & usually for a couple of years before they need to be replaced.
I’ve used many brands of 18650 batteries, these batteries are the best by far! I’ve got one set I’ve had for 3 years and they still hold a charge better than any batteries I’ve gotten from vape shops. Great product!

These are the best mod batteries that my husband and I have found! And they last forever! When we put them in our mods they last a whole day sometimes a day and a half. Highly recommend them!
This could be device related that is reading these batteries wrong. I don’t have another device (yet) to test that out on. But if it is the batteries, these last the least out of any battery (even one of lesser ) I have owned. Ever.
Sorry I'm not around to add photos to my
Post I'm just not around them at the moment but they are great batteries I enjoy them very much
They came here with good timing everything went well thank you
The best 3500 mah battery I've used, I have owned and used the mxjo, efest, and the lithicore all being 3500mah and 20 amp max with 10 amp constant and the mxjo's hold voltage the longest on average I usually use them from 4.2 volts and drain them to 3.6 volts on a unregulated mechanical box mod pushing two, 4 wrap Clapton's at .14 ohms at 1-2mm inside diameter both the lithicore and the efest are within 10% of the mxjo with both seeming to hit about 5% harder but 90% of the drain time of the mxjo from 4.2 volts down to 3.6 volts
I use these in my Vaporesso mod at 65 watts and they perform well, like my other IMRBatteries have in the past. You can't go wrong with these batteries.
My husband and I both use these batteries. They hold a charge much longer than any of the others we have used. They are forever our brand of batteries!
