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.

Battery safety is very important.  Mistreated batteries can get extremely hot and/or vent which could cause injury.  Always follow the following rules to make sure this doesn't happen.  We are not liable for mistreated batteries.

 

  • Never completely discharge batteries (below 2.5V under load or 3V unloaded).
  • Charge fully (to 4.2V) before first use.
  • Never use a lot of force on the battery to install
  • 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.  
  • Be mindful of the current limits in the specification and never exceed them.
  • Never keep a spare battery loose in a pocket, purse, etc.  Always use protective cases for loose batteries.  If it shorts against a piece of metal it can be very dangerous.
  • Never charge battery 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 battery then do it in a case or individual box in cool and dry place at approximately 3.6V - 3.7V.
  • Never try to charge or discharge li-ion batteries with battery chargers that are not made for Li-ion batteries.

    Great batteries from a great company

    These batteries are awesome. I know the 25R has been around for a while, and lots of newer higher rated batteries have come out since. For the price that these are available for, the real world performance / dollar ratio of these batteries still compare favorably well with the "better" ones in my opinion. I use 3 of these in my exo zenith mod at ~ 140-200 watts, and they push the amps well AND have respectable capacity. I highly appreciate Liion wholesale for being in business.
