Ultrafire CR123A 3.6V 880mAh Protected Battery 16340 2 Batteries

The Ultrafire Protected 3.6V batteries are a replacement for standard CR123A batteries in many applications. Sometimes called an RCR123A or Rechargeable CR123A

Some caution must be excercised as these cells are 3.6V, not 3.0V,and these cells are also about 1mm longer than standard cells so if you're using 2 in series you need to be aware that they'll be 2mm longer in total and outputing 7.2V(8.4 peak).These are the right choice if your using them in an LED flashlight or high powered laser pointers known to fit this type of cell .
