I bought these Keeppower 3V RCR123As three months ago and used it everyday in my Streamlight Protac 90.
This protected rcr123a battery provides a regulated constant 3V output, it won't drop voltage like primaries and most li-ion batteries.
It also has 860mah, almost double the capacity of a LiFePO4 battery.
It can only be charged with a Micro USB cable. My Nitecore UMS2 charger doesn't work with it.
Dimension: 16.6mm diameter X 36mm long
The length of this rcr123a is 2mm longer than a primary cr123a.
This is the main flaw of this battery, it won't fit some of the compact flashlights
These are the testing of some cr123a flashlights:
- Old Surefire G2/6P can easily fit 2 rcr123a and work perfectly.
- Surefire G2X MV can tightly fit 2 rcr123a and work properly, but one of the rcr123a got a dent from the tailcap spring>>>Not recommanded
- Surefire EDCL1-t fits and work perfectly, but the tailswitch is stiffer to press because the springs are more compressed.
- Streamlight Protac 90X can fit 2 rcr123a and work perfectly.
- Streamlight Protac 90 fits and work perfectly, my favorite EDC light!
- Insight WX150 & Streamlight TLR-1 don't fit at all.
Most flashlights with head and tailcap springs have more buffer to accommodate the longer rcr123a.
Output and Runtime
The regulated circuit in the rcr123a provides a constant 3V output until it drys out.
That means it can keep the flashlight on maximum output theoretically. I tested the keeppower rcr123a with my Protac 90 and EDCL1-T.
- The advertised runtime of the Protac 90 is 105min on high(300 lumens). In my test, it worked for 70min on high. the head and the body was warm but no problem.
- The advertised runtime of the EDCL1T is 60min on high(500 lumens). My light worked for 44min on high. The head was too warm to hold after 5min so I use fan to cool down to avoid damage to the light.
They all started at max output and then dropped to 90-95% brightness in about 3 minutes and stayed constant until a sudden off.
Some may not like the battery suddenly die without any sign, but I am really happy the constant high output.
Conclusion
The Keeppower RCR123As perform very well in my opinion. The regulated output and runtime exceeded my expectation.
This is a good replacement of the expensive CR123A, especially for some expensive light won't take 3.7V Li-ion (if it fits your flashlight).
Thank you for watching and sorry for my bad english. Cheers!
