⚠ 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 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.

These are the best batteries I've tried for my vape. They last all day long.
All batteries are working well. Hopefully they will last as expected. Satisfied with shopping here.
I enjoy these batteries very much. I love the high max amp and continuous discharge rate. I have never had an IMREN battery fail me.
best batteries I have ever got & used too thanks again good looking out
The price is fantastic, and as expected with IMR's: they work great! Shipping was quick, too. Oh, I loved the bonus battery case! I will definitely be purchasing all my batteries here from now on...
Good authentic batteries , Works well charges well I got them for my vape pen also comes with a hard plastic box, so you can transport them safely when not used .
Powers my vape all day long with no problems
These are the best choice of batteries for your vaporizer! They last the longest and hold a great charge for hours!
Awesome
These new batteries are great. They last 2 days in my mod. These are some of the best out of the box. Lifetime is decent on these batteries as well. Over 1000 uses on previous set before they became to worn to use. .
Its a well made and I ve been Im it for almost a month and I still haven't had to recharge it. Very beneficial to my line of duty
Great batteries for a good price. Fast shipping. Will continue to shop here.
I’ve used IMREN batteries for the last seven years and have yet to regret the decision!
My son has been looking for these batteries for a while now finally found them and they are worth every penny
Others may shame this brand and don't know what they are missing. Run these in a mech at .18 ohms with no issue. Change out once a day. After a year I pass them to a friend to use in their controlled mod.
These are my first experience with Imren batteries. First thing I did was run a capacity test and all four were at or above rated capacity. Internal resistance on all was .010 ~ .012 ohm which is excellent. I use a .15 ohm mesh coil at 95 watts and these batteries perform very well. I cannot comment on cycle life since I have been using them for only a few weeks but I am very satisfied with them so far. And you can't beat the price.
Even with shipping these were cheaper than anything comparable on amazon. Have been using them for a few weeks now and have had not issues, good battery life.
Hi quality long lasting. Perfect. Exactly what I wanted.
They last a while
……
I'm very satisfied with my purchase. Shipping was fast, packaging was neat. The battery looked and performed flawlessly. I will be out hasing more soon.
Works good in my hunni badger
Been using these batteries for a few years, have a long lifespan :+1: thank you for the awesome service! :v:ï¸
These batteries don’t last nearly as long as the average battery.
Great batteries, fast shipping
Easy to navigate site and order. Delivered as stated. Charge Lasts me a good part of the day
Power is good. Thought they would stay charged longer. Still like them.
Fast delivery They work fine
I use 2 batteries for my vape, and a pair last well over 12 hours of normal use. Other batteries that are similar don’t last nearly as long.
No complaints about them except for the fact that the wrap is pretty thick, the batteries do not fit in any of my tube mech mods that have very tight tolerances. They fit fine in my series box mods and DNA Sigeli mods, but they don't fit in my oil rig, nemisis tube mechs and they dont fit in my noisy cricket series box.
Great batteries! I buy 4 pairs every year to use for me and my g/f's e-cigs. Strong batteries that last a great amount of time. Durable design, never have any problems. After about a year of VERY heavy use, they start to hold less of a charge and need to be replaced, but they take a long time to die.
Ideal and long lasting!
Worked great for me
Amazingly fast delivery. Exactly what I ordered and the price wasgood.
Best battery
Exactly what I wanted. Not tested but label seems to match the power. No fakes. Would buy from again.
Recently bought and it’s been working great. Exactly as described
Very good, reliable battery
Got the batteries in less then four days. They work great with our vapes and charges fast
