26650 14500 16340 16650 18500 18350 CR2 battery rechargeable Li-ion |protected or unprotected| cells and battery chargers.

Orbtronic team specializes in the global sourcing, and manufacturing  of high quality | GRADE A | power Lithium-ion based rechargeable battery cells. 

Highest quality, and dependability by all manufacturing standards. 

Important | Safety guide |:

  • Never completely discharge li-ion battery ( below 2.5V under load ). These are not Ni-Mh batteries.
  • Charge fully to 4.2 Volts before first use.
  • Use only high quality Li-ion battery chargers.
  • Do not expose to heat. Never apply soldering tip directly to battery terminal.
  • Do not short (connect) positive, and negative battery contacts |intentionally, or unintentionally|.
  • Keep Li-ion battery that is not in use in plastic holder, or any other insulating material (e.g. plastic).
  • Do not charge battery over 4.2 Volts (another reason to use good battery charger).
  • Do not charge unattended.
  • Do not store your li-ion batteries fully charged (for an extended period of time [2 months, and longer]).
  • Store in cold, and dry place at approximately 3.7V (storage charge).
  • Never try charging (or discharging) li-ion batteries with battery chargers that are not made for 3.7V Li-ion batteries. Charging Li-ion battery without battery charger (with improvised devices) can be very dangerous. Li-ion batteries must be charged with battery chargers made specifically for Lithium-ion charging. 
  • If PVC battery wrap (tubing or sleeve) is damaged stop using that battery immediately, and rewrap with a new insulating heat shrink (wrap)
