⚠ 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.

This was my second set of Molicel M35a 18650 . Probably the biggest bang for the buck imo.
Excellent battery Molicel M35A. 10A CDR at low temps and low voltage drop under load. I recommend this battery.
Muy buenas baterías y el envio muy rápido y eficiente Gracias Atte Luis
I got 8 Molicel 3500mah 18650’s, They work great, I made a small portable power bank that can charge my iPad from dead to fully charged
Shipping was very fast. I was surprised because the batteries came in a nice plastic box. These molicel batteries are perfect for several applications I have in mind with my Raspberry Pi and Wyze cameras.
No disappointment from Molicel once again, this is my go-to brand from now on.
Winner of my Zebra tests
Seems to be working great for what I need it for was not sure but i've had no problems
These batteries were to replace my dead M12 battery pack. They sell for $90 new and the batteries are weak. These M35A replacements have a longer run time and superior output. They are the same size and with a couple soldering points revitalized this dead pack. I will be buying more of these batteries and fixing all my packs that have died from years of use. I love this product!
Fit well, work great, fast recharging. Have in a portable bluetooth speaker system. Keeps it running all day!
Too soon for a review, only got to start using them yesterday.
I've used them once and they seem to be pretty good.
Great Batteries?!!
Great Batteries?!!
My vape wasn’t right after purchasing similar Amazon batteries. I almost bought a new one but these were recommended to me and they fixed my problem and were a great price
Second order I placed with IRM.. Both orders were flawless!
Lasts all day vaping & fits ok in geekvape
Nice cells, good for high capacity projects
in my opinion they are decent cells not quite as good as my lghg2 but good cells
Using them for mouth-to-lung vaping in a box mod at 11 watts. They work fine for that and last for quite a while. I bought six of them as I have four box mods going at the same time with different juices in each one.
Great batteries, real 3500mah.
Good as rated!!! 3.5Ah
Fast shipping good packaging and not a cheap product Thank you!!
Work perfectly with my device.
Nice batteries. Very high quality
Great service!
It works well in my vape. What more can you ask for?
Battery charged and performed as advertised.
Good longevity.. Great service & accountability
great battery,
Good service
Navigating the site on IMR batteries is easy and functional.... easy to find what I need. The batteries themselves are working wonderfully, as expected. I use IMR Batteries for all my various battery needs. Stellar company !
These don’t work with my IMR 18650 batteries :(
Great 18650 Batteries with a nice non-shred wrap. Performance is about the same as the Sonys.
good for low wattage vape
Hours of charging, i only hope hours of awesomeness
Met expectations
Very satisfied in the shipping came on time
Batteries as described and arrived on time. Properly packed for shipping. Would buy from this vendor again.
