SAMSUNG INR18650-25R BATTERY GENUINE & TESTED - 20A (100A PULSE) 2500MAH - FLAT TOP

Genuine Samsung 25R 2500mAh batteries are a pretty new cutting edge battery cell from Korea that can handle some really high current.  This is the 25R5, the new green 25R.  

They are an updated version of the old "smurf blue" ones.  The 25R is one of our favorites from our testing at high currents.  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 real so you can be confident you've got the real thing. 

Note:  You may receive batteries from the Malaysia Samsung plant, which have an M on them after the model number so some people call them the 25RM or the INR18650-25RM.  These are the same as the battery without the M, are manufactured to the same specifications by Samsung SDI, and in all our testing show comparable performance 25R vs 25RM.

Warning: Lithium ion batteries may explode or burn due to improper use. Using these batteries for purposes not intended by the manufacturer 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. 

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 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
