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
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.
Pros650mAh Protected
ConsSlightly longer than the stock commerical batteries, making for a very tight fit.

I luv these critters
I have many devices that require CR123 batteries, and switched to rechargeable cells long ago. Bought generics first time around from Amzn; they were next to useless - short discharge times ans two leaked and ruined the lights... thanks a lot no-name company from China!

These Nitecore batteries have excellent build quality and long life when fully charged.
I first purchased 4, and liked them so much - I got 4 more.

Skip the cheap "blue" generics and spend a little more for Nitecore quality.

Works great in itp flashlights
These Nitecore RCR batteries save money and provide good output and runtime. I have itp flashlights that take one and two CR123 batteries and use these rechargeable batteries in them with no problem.
