The IMREN 18650 3000mAh powerhouse. LiionWholesale is pleased to bring you the IMREN 18650 new 3000mAh 40A battery. Rated by IMREN at an impressive 40A pulse and 20A continuous, this battery is a suitable high output, long-lasting competitor to the popular Efest 3000mAh. You'll see other listings for Imren 18650 3000mAh batteries, but compare the wrapper: these are distinguishable by their distinctive metallic gold wrapper with brilliant red lettering.

Big power, great appearance. Let's face it - appearance is not the first thing you have to look at when you choose a battery for your application. But if your battery is on display, or in a project where the battery is front and center, it doesn't hurt that this battery sports a metallic gold wrap that's as functional as it is nice to look at.

IMREN direct. Our IMREN batteries are purchased directly from the manufacturer, guaranteeing their authenticity.

Free IMREN Cases for every pair of batteries. If you buy 2 batteries, you get an IMREN dual case for free with every pair, even in wholesale quantities.

Battery Warning

Warning: Lithium ion batteries may explode or burn due to improper use. Using these batteries for purposes not intended by the manufacturer, including outside a battery pack and/or without a BMS, may cause severe injury and damage. We are not responsible for any injuries caused by lithium ion batteries - use at your own risk.

All rechargeable batteries have inherent risks under any circumstance. Use caution with working with li-ion batteries (lithium-ion), LiPo (lithium ion polymer), and any rechargeable cells (together "rechargeable batteries"), as they have dangerous charging characteristics and are known to explode or burn if mishandled. A purchaser and user of rechargeable batteries should educate themselves on rechargeable batteries, especially as to charging, discharging, assembly, and storage. Learn more about proper storage and care for rechargeable batteries here. We are not responsible for any damage caused by the misuse or mishandling of rechargeable batteries.

Here are a few tips:

  • Never completely discharge batteries (below 2.5V under load or 3V unloaded)
  • Charge fully (to 4.2V) before first use
  • Never charge batteries to 4.3V or above
  • Do not charge unattended
  • Do not store your li-ion batteries fully charged for an extended period of time (weeks or more)
  • If you must store your battery, only store in a case or individual box in a cool and dry place at approximately 3.6-3.7V
  • Use only high quality battery chargers
  • Do not expose to heat
  • Do not connect the positive contact to the negative contact without an appropriate load
  • Never exceed the battery's specifications
  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for li-ion batteries
  • Always charge these batteries on and within fireproof material
  • Never leave rechargeable batteries in a recharging station unattended
  • Do not use any rechargeable battery or charger if any visible damage is present, or if known mishandling, accidental or otherwise, has occurred
  • Always store and transport rechargeable cells in a safe, non-conductive container (never keep a spare battery loose in a pocket, purse, etc. and always use protective cases)
  • Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)
  • If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside
  • If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire

Great 18650's with 20A/40A 3000mah

I only shop for Li-ion batteries on Liion Wholesale cause I know I'm getting genuine batteries for all the brands they have in stocks and their prices and quality of service is unbeatable. I bought two of these IMREN 18650 3000mAh 20A/40A because I wanted a high mAh 18650 and I needed some with a max Amp rating and the IMREN case that comes with when you purchase two at a time is a nice lil bonus.

Haven't used them yet!

I can only review the 2 batterries I purchased previously, since I just got these new ones, hence the 4 stars. I don't yet know if the new IMREN will perform as the previous batteries did. I like this brand better than the Sony 18650 3000mAh simply because they had a longer useful life than the Sony. I recycled(dispossed of) 4 of the Sony batteries before the 2 Imren finally became too weak to bother with. Per Li-ion Whsle directions, I charged all batteries in a seperate slow charger I bought from them. It takes approx 6.5 hrs to charge each battery, which is why I have multiple batteries. Both brands kept their charges for about 24 hrs of use in a vape mod set to low levels, but the IMREN lived significantly longer. Can't say how any would perform with fast charging.
