⚠ Important Safety Warnings
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. Click here to review the full safety guidelines.
- 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.
- 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 for e-cigarettes, vaporizers, or similar devices.
-
Thermal Runaway: A chain reaction where heat from a failing battery
causes further overheating, potentially leading to fire or explosion.
- Causes: Overcharging, short circuits, physical damage, or exposure to high temperatures.
- Prevention: Use a smart charger, avoid damage, and store batteries in a cool, dry place.
- Storage & Transport: Always store batteries in protective cases 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. Continued use could result in failure, fire, or explosion.
- Charging: Use a smart charger specifically designed for lithium-ion batteries and ensure the charger's voltage matches the battery's specifications. Never overcharge, over-discharge, or leave unattended while charging.
-
Prohibited Activities:
- Do not expose the battery to extreme heat, fire, or liquids.
- Do not short circuit, puncture, crush, or modify the battery.
- Do not charge or discharge beyond the manufacturer’s voltage range.
- Do not dispose of in regular trash—always recycle at approved facilities.
- Emergency Response: If a cell shows signs of thermal runaway (e.g., 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 combustible materials. Lithium-ion cells burn as Class B fires — use an ABC / dry-chemical fire extinguisher, or douse with large amounts of water to cool the cell and prevent the fire from spreading. 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 intended for lithium-metal batteries, not lithium-ion.) For any fire beyond a single small cell, evacuate and call emergency services.

All good
Fast shipping! Great batteries!
Currently using the batteries. They work amazingly!
My go to battery, period.
The MXJO Type-1 battery is amazing. 3500mAh is the most juice you can get out of a single 18650.
They me up to 2 days @ less than 100w. I originally bought them for my single battery rx75 mod but they have a hard time keeping up @60+ on low resistance, but that's what the 30amp Samsung's are for. If your looking for a quality battery that holds up for a full day in 2+ battery mods you will not be disappointed.
The batteries seem to perform well. Thanks!!
.

Great batteries good price and availability shipped quickly.
Fast shipping, great price! Holds a charge very well.
Exactly what we needed!
On time and is working great!
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.
THE ONLY BATTERY YOU WANT, LONG LASTING NOT A KNOCK OFF. WILL LAST 12 HORS WITH CONSTANT USE.
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
Long lasting
Working good, thanks
Best price online and these last forever when charged. Thank you!
Fast shipping!

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!
