New PCB protected button top version of the Sanyo NCR18650GA.  This is a 3500 mAh 10 A battery and is one of the best batteries we offer for high discharge flashlights or other devices that need a high capacity but medium discharge protected battery.  Its main competitor is the protected LG MJ1 which is a great alternative.

These are manufacturered with a very high quality Seiko PCB with AO MOSFETs for 12-13A high current cutoff (most PCBs will not allow this much current).   This protection circuit protects the battery from mishandling, overcharge, or overdischarge while allowing the battery to do its job properly.

The cell is made by Panasonic.  Our company then adds the very high quality Seiko PCB along with the button top in an ISO certified factory to all safety standards.  A clear wrap is put over the top to hold it together while still showing the Panasonic wrap underneath.

Appearance may vary, as the Sanyo and Panasonic NCR18650GA versions are equivalent but have a different wrapper.

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.

    Hickups but excellent recovery

    I bought 16 of these cells. Prompt delivery. The cells were not satisfactorily assembled when adding the protection circuitry. I contacted LIion about the problem. They understood the issue. They had found that a normally reliable sub-contractor had not provide the normal level of excellence in a batch. I was offered a replacement for the worst cells I had looked at. I was seriously concerned about what else, not easily visible, problems there might be. I asked to replace the batch. Immediate response agreeing to replace all cells. Replacements sent IMMEDIATELY with a prepaid return envelope to leave at my door for USPS to pick up. Outstanding service for a customer problem. No hassle to me. And a couple of free cell holders for my trouble. Fast and honorable. I would not hesitate to buy from this vendor. Good prices and excellent drive for customer satisfaction!

    Excellent Cells at an Excellent Price

    I changed my order to the same quantity of unprotected cells, after it was clear that the first order was missing somewhere on the delivery route. Customer service was excellent, and the second order was promptly shipped after I called to report the missing package. Best value I found on the web for these cells.
