⚠ 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.

Shipping was fast and batteries are cheap and great!!!
Great price, quality and service!
Easy, fast and reasonably priced, great job, highly recommend.
The batteries are good. They do as expected. As far as the shipping it was very slow. It took a week for the package to get from Texas to Oklahoma. I could have drove there and got them faster.
Very reliable Quick shipping A great place to deal with!
These batteries are the best bang for the buck. They stay charged until they drop. I will buy them again when I need batteries again.
so i have used the imren brand for sometime now they perform very well for my battery builds and solar banks and imr has the best prices on this brand i like the deferent shipping options but shipping prices out of control these days so standard shipping it was even then still cam fast. the thing i like the most is honestly the sticker and battery heat wrap thing so awesome now this a company that cares about it customer's and i will only buy batteries from imr this my go to place.
Great price, top quality battery, these were so affordable i bought 6 for less than i usually pay for 4. Thanks
Batteries arrived in just a few days for repair to ebike battery. Used LiitoKala Lii-M4S to charge/ discharge and test batteries before install. All batteries charged to 4.2v and all tested above 2500 mAh (2673 mAh to 2830 mAh).
I was so happy when I found this it’s so much better then paying $50 a battery
As advertised! Excellent price!
Best for the price, period. ever.
Excellent right out of the carton.
I always double check with mooch to make sure a given cell fits an application. For mine this fit the bill at less than the price of Samsung 25r. On time shipping and no hassles. Plus as always free battery boxes.
great
Works good and holds a decent charge that lasts a good amount of time
Good batteries, would purchase again
need more time to access , there durability under operating systems. So far they seem to be doing ok.I will reorder in the near future.
They all shipped at about 10% charge and so far about half of them get super hot during charging
Great batteries and packaged very well. Love the sturdy plastic storage cases they came with and the extras in the box as well.
These last even longer then our last set we ordered. Pretty basic battery but does great for us.
This was exactly what I was needing
Amazing batterie at a great price
I bought some batteries from iMRbatteries.com before and also bought a couple batteries off Amazon. The ones from Amazon stop holding charge several months ago but the ones from iMRbatteries.com are still holding strong charge so I bought four more from them and will never buy batteries from anywhere els. I highly recommend iMRbatteries.com to anyone looking to purchase batteries!
Batteries worked great, love the cases.
Great batteries 🔋
Great shopping here. Nice prices. And shipping time is excellent
A great company
Super quick shipping came in just a few days!
Batteries arrived in short order, well packaged, nothing wrong. I inserted two of them in non-functioning solar lights to no effect. I feel certain there is nothing wrong with the batteries, rather something else malfunctioning in the lights. Can't really give a review, as I haven't figured out the problem yet.
Didn't take long to get to me and they work great.
Came as expected. Safe and Secure!
Fast shipper, battery's work perfectly, no problems
They don't have much life to them and there's no warning that they are about to die other battery's you can tell get weaker these run fine then dead
batteries don.t last long. not as good as others that i have used
The batteries are working great. I like they came with extra storage containers. I use one for charged and one for depleted, don't have to guess.
Repeat buyer. Great batteries!
Batteries shipped fast and are working perfectly.
Shipping is always fast. The Imren batteries are a good midrange battery.
