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.

    • What device/application do you use this with? Radio

    Good Experience

    Exactly as advertised. This is a nice cell and will be used in a 2S pack for a radio control transmitter.


    Diggin' these!

    I got these after a couple years of strictly using the 25R. For me, someone who really doesn't see the need for exorbitant amounts of current, these work excellent! They last me nearly two days, don't have a very noticeable "drop off" like some batteries, and also work wonderfully for a day of testing my PWM PCBs as well as powering 10W LEDs for my photo box. Just a little hint to those too simple to try and pull the sticker off... PULL THE FREAKIN' STICKER OFF! Those stickers are used for keeping track of the cells, just peel the thing off, viola "LGDBMJ11865" = real LG MJ1


    #1 cells in my flashlights

    I've ordered these 3500 mah cells in both flat top and button numerous times the last few months & have become my main cell for use in my Armytek wizard / Nitecore Tm36 / Eagletec mx39 and others. I rarely take them all the way down but they still take Aprox 3100mah charge. Out of two dozen I've never received a bad cell or had one fail to date. There is a paper sticker that appears to have been applied by liion whse that indicates the mah because the factory print on the wrapper is the part description. Why would I buy twice the some place else when these performed perfectly. Yes I recommend these & will continue to buy them.



    Cheap knock-offs find another distributor. These have a sticker not a printed label. I purchased 2 batteries and both of the batteries had DIFFERENT stickers on the them!! :rage: I wish I could give negative stars.
