Nitecore NL166 RCR123A

Rechargeable CR123A Battery

The Nitecore N166 RCR123A Battery is a highly capable Lithium-Ion battery designed specifically for high performance electronics. These powerful RCR123A batteries deliver an impressive 3.7 Volts of power and can hold a charge of up to 650 mAh, making them perfect for high drain devices such as LED flashlights, video game consoles, cameras, appliances, and more. The cells come standard with a high-performance protection circuit that provides overcharge and over-discharge protection, safeguarding themselves from possible internal damage that could lower their capacity, ensuring they last as long as possible. The NL166 is capable of being recharged more than 500 times, making it both cost effective and environmentally friendly.

Safety First

Just as impressive as the NL166's power is its sophisticated safe design. The RCR123A batteries are equipped with a nickel-plated S.S. protectors at both ends to provide high impact resistance, good electrical conductivity and oxidation resistance. To prevent abrasions and other external damage, the NL166 cells are coated with a durable metallic film, while its circuit board is coated with an ultra tough plastic. The cell's innovative anode is designed to resist high temperatures, while a micro-porous barrier within the battery protects its delicate internal components. The battery even features a specialized pressure relief valve that activates if the battery experiences a rapid temperature increase.

Features:

  • Built-in high-performance protection circuit prevents overcharging / over-discharging
  • Nickel-plated S.S. connectors on both ends for superior impact resistance, electrical conductivity, and oxidation resistance
  • Durable metallic film coating protects against abrasions and other external damage
  • Pressure relief valve activates in the event of rapid temperature increase

Great Battery
June 8, 2016
I would have rated the batteries a 5 star if they were just a little shorter. I got 8 of them for my Arlo-Netgear Wi-Fi cameras. I found that they are just a little longer in length than the standard batteries. They are a very tight fit in the Arlo's. Each battery was packed in a blister pack upon my receiving them. I put them on my Nitecore charger for a full charge, let them rest, and installed them the next day. So far all is good with the Arlo's. I'll see if I can update this review at the time when the batteries need recharged.
Pros:
650mAh Protected
Cons:
Slightly longer than the stock commerical batteries, making for a very tight fit.

Nice quality
March 1, 2017
Works just as described, but don't buy it for the Olight S1R. The max turbo mode won't work.
Pros:
Nice quality at a cheap price.
Cons:
The max turbo mode won't work If used with my Olight S1R turbo.

One out of two dead after four uses
February 14, 2017
I bought two of these, and one of them died on approximately the 4th charge. It got quite hot, and when I took it off the charger it measured only 4.09 volts. I'm rather glad I caught it before it burned down my house. The other one is still great so far. When working, they provided adequate current to run an Olight S1 on high mode, which requires more than an amp. Although these cells supposedly have a 12 month warranty, it turns out to be worthless in practice. I wrote to the manufacturer, and they said I could either return it to the dealer (batteryjunction says they will accept returns only for the first 30 days) or ship it to them directly in China. It would cost more to ship it to China than it is worth, assuming I could find a carrier willing to ship defective lithium ion cells at any price. It's likely that I just got unlucky and yours will be fine. One can't conclude much statistically with a sample size of 2. Nonetheless my experience did not inspire confidence in their quality control.
Pros:
Provides high current Protection circuit cuts off when voltage gets low to avoid overdischarge
Cons:
50% failure rate in my sample Worthless warranty

Good Battery
January 18, 2017
Yes they are $6 for one, but they seem to work well. I wish they they could pack a few more mAh into it for the price.
Pros:
Works well
Cons:

Awesome batteries
January 4, 2017
After doing a ton of research on what rechargeable batteries would work with my Arlo camera system, I bought these. They have now been in my cameras for over 2 weeks and still show full charge. I could not be happier. I also bought the NiteCore D4 charger (bought from a different vendor) to charge them.

Great battery, a little long
November 4, 2016
This replaced a 123 battery, but note that they are .15" longer because of the protection board.
Pros:
Good replacement
Cons:
You need to account for the length

Just what I ordered
September 20, 2016
Came on time in a sealed blister pack. Opened them up and put them in the charger, and both took a full charge. Used for a small but high lumen flashlight. It is an exact replacement for the ones that came with it. Watch out for cheaper batteries that don't have the same maH rating.
Pros:
High output, rechargeable
Cons:
none

Great, no reservations, would buy again

Works great with the nitecore I2 charger. Charges relatively fast and drains slowly when not in use. Save money and environment with rechargeables!

Dead End
December 16, 2015
A good rechargable battery with a major issue. The battery does hold good power right to the end where at that time your flash light will just turn off because loss of sufficient power to run your 1000 lumin high drain light. Now....is this the batteries fault or is this the new Flashlights hitting the market today with the technology that keeps your light from dimming until the end...Do you really want that happening????
Pros:
A good battery rite to the end... I recommend for household use but have spares.
Cons:
Dies at end of life. Pls read my full comment.

Great in my older torch
November 28, 2015
Have a very old, but still unique and useful torch (Striker VG) and was advised I might fry it if I used a newer, hotter 18650. Took a chance on two Nitecore RCR123As and they work great. Buying two more for my single 123A EDCs. This will make me all-rechargeable. I've found every Nitecore device I've purchased through Battery Junction to be first class.
Pros:
Durable cover. Takes and holds a strong charge.

Great battery
September 19, 2015
With the cost of 123 batteries, buying these has saved me a ton of money and they work and seem to last longer then a non-rechargeable 123 battery.
Pros:
Cost-saving over time; long-lasting
Cons:
None

Is the light suitable for rechargeable batteries
February 26, 2015
I purchased the NITECORE RCR123A battery to be used in my Streamlite EDC light. When I installed the batteries in the light the light would not work. I then tried the batteries in my SureFire E2D LED defender light and they functioned fine. With a little more research I was told Streamlight and Surefire did not recommend rechargeable batteries for lights that do not initially come with rechargeable batteries. Installing rechargeable batteries in these lights will void the warranty. Be sure the light you are purchasing these batteries for is able to except rechargeable batteries.
Pros:
I have no input on the long Jevity or the runtime of these batteries.
Cons:
They will not work in all whites.
