- Great product
I have a single cell flashlight that I use these in. I can get a couple of weeks out of the battery. That is a little shorter than non rechargeable batteries. However, you get to use them over and over.
I think they will save money. If you use your flashlight a lot.

- Safe and plenty of runtime
Lithium-phosphate batteries offer safe chemistry, no unexpected shutoff from a protection circuit, and plenty of runtime. I was first concerned about runtime of lithium phosphate, but the true reality is I need to refresh my batteries only a few times a month.
The battery charger is the proper CC/CV, 3.7v, 300mA, and can charge one or two cells at a time; this keeps your batteries safe and extends their duty cycle.
I'm very happy to now have safe batteries with plenty of runtime. There's no compromise in quality and function.

- A good idea
Having a dual voltage unit is a good idea. Especially when traveling. I find 12 volt DC charges the cells very quickly, which is a plus.

- LFP 123A batteries
These batteries don't hold a charge for very long, they are only 600 mili amps each!

- Cost-Cutting Approach
I use my E2D daily on evening walks and I have found this charger and batteries have save me $$$ already. The batteries don't provide the same operating time as the regular cells, but I only need to charge them about weekly so there is no issue. When I travel, I always carry a spare set of regular cells just in case I'm where I can't recharge.

- SF2R-KIT01 (Awesome)
I've used this kit now for about a year. It works great. The batteries stay charged for a good long time. I would estimate the run time as being 80 to 85% of regular Surefire batteries. Time to charge is measured in hours...I estimate about 4, but I usually let them charge over night. I did however blow a regular lamp in one light, so believe the warning. (LED only)

It either quit charging the batteries or the batteries went dead shortly after getting them

- small, compact, economical
You're gonna save a lot of money and time with this device the charge time is explained on the back of the charger. The light is red when charging then turns green when ready to use for LED flashlights.

- Charger and Battery Review
I don't usually take the time to write these, although I do benifiet from others reviews all the time. Here it goes...great charger and good batteries. I also have a Tenergy cr123 charger, it works fine although It has that made in China feel/look. Its charge light stays red and then pops green when done. This K2 starts red and slowly turns orange/yellow then green as the charge progresses on the battery. Cool feature, lets you know where the battery is in the charge. Quality built housing, positive feel on the hook-ups. It doesn't say SureFire on it but sure feels like SureFire. BUY IT, you won't regret it! 5 Stars. FYI check out GoalZero for AA or AAA, they got some cool stuff too.

Do not use LFP 123A batteries with incandescent illumination tools. See Restrictions below.
Kit includes two LFP 123A lithium-phosphate rechargeable batteries and a combination wall (AC) and car (DC) charger with appropriate AC and DC cables. These 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 charger, which features a charge status indicator light, will charge two LFP 123A lithium-phosphate batteries simultaneously. The runtime of these LFP 123A batteries is approximately 50% less than the runtime 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.
- Combination wall (AC) and car (DC) charger simultaneously recharges two lithium-phosphate batteries (included)
- AC/DC charger features indicator light
- Two LFP 123A lithium-phosphate rechargeable batteries provide hundreds of charging cycles
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. The included charger should not be used to recharge disposable 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."
