Genuine Samsung INR18650-25R 2500mAh batteries are a great battery cell that can handle some really high current at a great price. This is the 25R6, the newest version of the green 25R. Note this is even newer than the 25R5. The 25R is one of our favorites from our testing at high currents. The 20A rating is very conservative and they tend to outperform other 20A batteries. The problem is there are many counterfeits on the market but you can be sure these 25R's are genuine. We've done extensive testing to be sure they're authentic so you can be confident you've got the real thing.
There are both a Korean made and Malaysian made version of this cell. The Malaysian one says "25RM" while the Korean one just says "25R". These are made to the same specification and perform the same so you may receive either one from us. If you require a certain version you can contact us to see which we have in stock.

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

Everything was great!
Great batteries, great price!
The product was great. These batteries are always the best there are. The only problem I have is I ordered 6 batteries and payed extra shipping for the free gift. I only received 4 batteries and 1 free gift. I was very disappointed, as I always buy my stuff from you. For the first time in 6 years I didn't get what I ordered. I have a feeling none of this will matter to you! And you may have just lost a customer that buys from you quite often.
