Works great for me
"Works great for me, installed in my Streamlight TLR-7X."
Great batteries & Great website!!
"These batteries, fully charged, put out an amazing 4. 2 volts! They meet and exceed all my needs! I use them for weapon mounted lights, and they are brighter than ever! Also, Battery Junction is the best place to purchase them, with the lowest prices and the fastest shipping! Thanks! ;-}. MM"

Q&A
- Are these batteries 3volt or 3.7 volts?
- The battery is 3.6V
- What is the size of the battery. I want to make sure it will fit my charger before I buy it
- This is equivalent to a 16340 (RCR123 size) - it comes with a built in charging port but can also be out in a charger as well
- Are these LiFePO4 3.2V, or the usual LiCoO2 3.7V?
- Streamlight is not providing us with the chemistry other than lithium ion - that would state that it is not a LiFePo4 battery.
- Do the batteries come with a USB-C charging cord? Can these batteries be used interchangeably with standard CR123A batteries or just with the TLR-7X?
- The SL-B9 are not an equal equivalent to a CR123 since the SL-B9 are a higher voltage at 3.6V and a standard CR123 is 3V - they do not come with a USB-c charging cable.
