⚠ 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.

Great battery life and holds up to high wattage usage!
Batteries are working great. Actually last a full day of excessive use.
Very happy with the batteries they work fast shipping highly recommend
I bought a set of these batteries. About 3 yrs ago. And when it was time to invest in another set. I bought these again. To me they held up the best. Compared to other brands I've purchased throughout the yrs
The batteries are of very good quality and construction, come protected in plastic cylinders and brings additional a plastic shell to take them anywhere. They really are the best.
I use these in all my regulated mods and they work great!
Batteries always fresh and ready to go from a company that puts it's customers first. Always provides battery wraps and carry cases with purchased batteries. Love you guys
Came in good condition, shipping was pretty fast, and batteries are authentic and have great power. Thought battery life would be a tad longer, it is but not by as much as I thought. But I'm running 3 in my rx200 at 70watts. It lasts for almost 2 days without charging
Great quality and long life under heavy use!
Perfect replacement.

Fast Shipping batteries last a long time.
I love these batteries, I've used them for years. The last ones I bought, set of 6 lasted over 3 years using them in my vape mod. These are the best in my opinion. This was the first time I have used 18650 batteries and I'm very happy. They arrived on time and in perfect condition. Thank you 18650.
Batteries are great and fast shipping. Thanks
Great product. Quick delivery.
quick and easy purchase, will use them again if I need vape batteries!
I thought there would be 2 batteries. I thought wrong
Just what I ordered and arrived early
Fantastic batteries!!!
Mxjo is the most dependable I’ve found. Been doing this for 10 yrs. I left 2 of them out in the garage for 5 yrs and they work like new. This is the one you won’t have to replace.

Excellent batteries they last forever
Possibly the best batteries for many vape mods. Last for many hours of use per day and rechargeable for years. Dependable, sturdy. Good price.
So far so good. Hard to tell in the long run but I am sure they will be great.
Good
First time trying these and they seem to work really well. Been wanting to try some mxjos for a while but never really Justified it when they were like 10.99 a piece, but now that they have went down it seems to be a good battery.
Best batteries for vaping
This battery is a lot more powerful than the other ones I’ve seen. I can use it daily without having to charge it for a whole day. It lasts for 24 hours.
Thank you many many more years of quality service and products
