The Trustfire 16340 batteries are a replacement for standard CR123A batteries in many applications. Sometimes called an RCR123A or Rechargeable CR123A, these cells may be longer than a standard CR123A. Caution must be exercised when using these cells, as they are 3.6V, not 3.0V as is a standard CR123A. The length of the cells are longer than a standard CR123A (up to 1-2 mm longer), so if you're using 2 in series be aware that this extra length will be doubled (up to 4-6 mm) and the cells will be outputting 7.2V(8.4V peak). These are the right choice if you're using them in an LED flashlight known to fit this type of cell - otherwise, we recommend our Tenergy cells linked below.

• Rechargeable CR123A Li-Ion Batteries with 3.6V working voltage and advertised 880mAh capacity.
• Can be recharged up to 500 times.
• PCB protection against: Over-Discharge, Over-Charge & Short Circuit.
• Dimensions*: 36 mm Height x 17 mm Diameter (+/- 1 mm) (Note: Longer than a standard CR123A battery, may not fit all devices that use CR123A's)
