⚠ 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.

Customer Reviews
Overall rating: 4.7 / 5 from 47 reviews.
Very pleased with the performance of the 3.5 AH cells. I also tested them and they produced at or better than specified.
Good price, fast delivery!!!👍
This was not a 1860 battery that fits my devices, and they will not offer a refund. Buy from Amazon!!
I wish I knew about your coupon offer but I have already installed the batteries in my digital multimeter (DVM). Batteries work perfectly and arrived packaged well and in perfect condition. I'm hoping you can make an exception on the coupon but if not, I still appreciate your service and quality. Thank you, Gary (K9HDU@aol.com)
Works, and shipped in a timely manner 👍🏽
Quick and easy ordering with fast shipping. Great quality products at a great price. Will make many more purchases in the future.
Best battery so far!
Always top notch batteries I love this store. Thank you
Arrived in a reasonable time and work perfectly for my project! Will purchase from here again
Best performance of the many 18650s I have tried
great cells good price!!
Muy buenas
Muy bien buena calidad lo probaré
The items were as described. I am happy with the website and purchase process.
They work well!
Seems to be good batteries in my high drain devices.
Excellent quality battery. Exceptionally well priced with very fast shipping.
Quick shipping. Quality cells, very happy with the purchase
Shipping was great, batteries are great, and customer service was very quick and helpful. Thanks!
To replace my Omnicharger battery bank batteries, this was actually an upgrade to the capacity of the bank as well
I’ve heard great things about Molicell and have found everything I heard to be true. It’s a good quality, accurate labeling and dependable product. Thank you and I will be shopping again with Molicell👍👍👍
Initially had very low charge, had to charge it with one of my Radio Control chargers
Came in secure, robust packaging with no damage and preformed as advertised.
Prompt and great products
REALLY GOOD CELLS AT A FAIR PRICE. BUILDING A PACK FOR A YETI MOUMTAIN BIKE.
fast shipping and they work great
Seem to be genuine cells. A little over 3300 mah each on a low quality Chinese tester. The little case was a nice touch.
These are good batteries, but not my preference but great for a backup battery. The charge is decent too may not last a complete full day but close. Charges pretty fast too. Not all were completely charged when they arrived. But overall happy with the purchase.
Worked perfectly. Thank you.
Wrong battery
works just fine
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
