- Great rechargeable batteries
I am in law enforcement and use these batteries in my stream light polytac led. The run time is pretty good about 1.5 to 2 hours. That is at about 120 lumens or so. My co worker has a 600 lumen light but they lat him about 30 minutes. So take that into consideration. They charge quick, the company says they hold charge for 3 years and can recharge 2000 times. Good for 200 lumen or less flash light in my opinion or if you have a red dot or something they would work food for that too. But you can recharge the battery every night if you use it for work and you get a lot of bang for the buck if you get 2000 charges out of it.

- Great but one issue
I bought these and they are awesome. I bought 2 sets but one battery is like a fraction shorter so it doesn't connect with the charger. I called about it and they never did anything about it.

- Great batteries
I have several surefire flashlight and now I can save money. The sf2r-cb are great; save some money and buy this batteries.

- Saving Money on Batteries
Compared to purchasing 2 new batteries every month, the LFP 123A batteries will pay for themselves in less than 3 months.

- Batteries worked for two seconds
Ordered two sets charged both, neither pair worked, could it be a bulb, I have only used one box of 24 batteries. The expense and time already invested makes it difficult to invest more time and money.

These batteries work well, but most have such a soft negative end plate that they collapse and then won't charge due to lack of contact to the charger terminals. The lithium batteries seem to last 2-3 times longer than a typical charge, but overall it's much cheaper to recharge and have a spare set on hand.

- Terrible charge
I charged these batteries like I was suppose to but the batteries don't keep a charge very well. I have to charge them after just 20 minutes of use. I am very mad about this because I paid way too much for batteries that have to be constantly recharged

- Cr123 rechargeable
I have found great success withis product. As a professional security contractor, I rely on these on an hourly basis. The name Surefire alone, carries a great deal of expectation. These batteries indeed live up to the name that " Surefire ", implies. I highly recommend this product for any operator, or for ANY other day to day user in need of the finest illumination tools, and ancillary products which are needed to get the job done. KRUSHER.

I bought these for duty work and they work great with my Surefire 6P LED light. The downside is that they will not work in my pistol tac light. I contact Surefire about the issue, and they told me that they were not the same specs as commercial batteries, and they were probably a mm or two shorter, and thus more might not work in other items. That is fine with me as I rarely use my tac light, but use my flashlight multiple times a night. I have had two sets of batteries that get rotated as needed from charger to light, and they have been running strong for over a year now. I know that one set has even been through the washer with the light. You would never tell other than they were cleaner. Great products all around.

Do not use LFP 123A batteries with incandescent illumination tools. See Restrictions below.
These two LFP 123A lithium-phosphate rechargeable batteries—which retain approximately 50% of their original capacity even after 500 charging cycles—will power SureFire illumination tools that use disposable 123A lithium batteries. The runtime of these LFP 123A lithium-phosphate batteries is about 50% of that provided by disposable 123A lithium batteries; maximum output levels are typically not affected. Use of these rechargeable batteries can result in a cost savings over time, depending on usage habits. Recharge only with AC/DC charger included with SF2R-KIT01, sold separately.
- LFP 123A lithium-phosphate rechargeable batteries provide hundreds of charging cycles
- Use of LFP 123A batteries can result in cost savings over time, compared to disposable 123A lithium batteries
- AC/DC charger sold separately
Warning: As with disposable 123A lithium batteries, do not mix rechargeable LFP 123A lithium-phosphate batteries with other types or brands of batteries, including but not limited to 123A lithium batteries.
Rechargeable LFP 123A batteries are only to be used to power LED illumination products (built to use 123A lithium batteries) and NOT those featuring incandescent lamps. The initial elevated voltage of these rechargeable batteries, immediately after charging, may cause the filament contained within an incandescent lamp to break or “burn out."
