ARE YOU A PRO? Join for FREE!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.

"These batteries are very good. Have never purchased these before and was seriously impressed with the performance. These have slightly more mah than stated,at least mine do. They are reliable for duration and are in my small lights that are over 1000 lumens. The 18350 size I've purchased before and are also great which is why I tried these. Well worth it, will buy again when needed."
"The Trustfire RCR123A/13640 is not a direct replacement for standard CR123A batteries. I found out the hard way. My bad, I failed to detect that in the online descriptions and, yes, the precaution is there, I failed to see it. They are 2mm longer and do not fit in the two flashlights I intended to use them in. One flashlight is an Eveready PMHT2L and the other id a Kobalt (Lowes brand?) of unknown part number. They work in the Eveready provided I do not screw the cap on tightly. For the Kobalt I can not screw the end cap on at all. They are probably a fine product, my one star rating reflects the unusability in my applications"
"These batteries are longer, they don't fit."
"As stated due to the over charge protection circuit these batteries are to long to use in some flashlights and other applications, also although they are rated at 880mah most of them only charged to around 790~800 mah according to my test charger. these where bought to replace older batteries that have long since died on me and so far its not looking to bright for these."
"This battery is not the standard size for a 16340. I tried them in three different brands of weapon lights that has a door/latch for the battery compartment and none would close. You will probably be ok if your flashlight has a screw on cap. I talked with customer service about this issue and they are aware of the size difference."
"Very Good Batteries! Long lasting and affordable!"
"Bought these for my blue, star laser pointer. These little batteries more than filled the bill, they kick celestial butt!"
"They are advertising this battery as a 16340. That number has a significance. It stands for 16mm in diameter by 34. 0mm long. Beware!. . . . these batteries are larger than standard 16340s in both dimensions. They are 1mm larger in diameter and 2mm longer in length. This may not seem like a big deal, but if you are intending them to fit into a holder that is designed for actual 16340s, you may be SOL! They do have the dimensions, measured in inches, listed in the spec chart on the web page for these batteries but I never thought that i would need to double-check the dimensions of something that has a dimension as part of its name. . . ."
"Great batteries, I purchase this battery for my rifle laser. I'm surprise how long they hold charge. It been in the laser in the safe for 4 month and still bright as ever. Used it for an hour and still going. probably should recharge it."
"This battery gives me about 40 minutes on high setting with a Sure Fire 600 Lumen flashlight. Much better than some 'Higher Capacity' rechargeable CR123's"
