Description

Nitecore NL189 18650 Battery

3.7V 3400mAh

Incredibly powerful and remarkably safe, the Nitecore NL189 18650 Battery is the best 18650 on the market! These incredible Lithium Ion batteries deliver an impressive 3.7 Volts of power and are capable of holding a charge of up to 3400 mAh, which is 62% more than the average 18650, making them perfect for high performance devices like the intense LED flashlights from Nitecore, as well as video game consoles, appliances, and more. The NL189 comes with a sophisticated high-performance protected circuit that prevents the cell from overcharging and discharging, which can cause long term damage to the battery. The cell is capable of being recharged over 500 times, making it not only cost effective, but environmentally friendly as well.

Safe Design

Nitecore understands that safe use of a battery is just as important as the battery's production. Designed with safety in mind, the NL189 features nickel-plated S.S. protectors at both ends that give the cell superior impact resistance, better electrical conductivity and quality oxidation resistance. To prevent against abrasions and other external damage, the cells are coated with a durable metallic film, while its protection circuit is coated with hard plastic. The battery features a unique anode that is designed to resist high temperatures, as well as a micro-porous barrier on the interior that protects the delicate internal components. The cell even comes with a specialized pressure relief valve that will activate in the event the battery experiences rapid temperature increase.



Features:

  • Intelligent protection circuit prevents overcharging / over-discharging
  • Nickel-plated S.S. protectors on either end provide quality impact resistance, electrical conductivity, and oxidation resistance
  • Durable metallic film coating to protect against abrasions
  • Micro-porous barrier on the cell's interior protects internal components
  • Pressure relief valve activates in the event of sudden temperature increase

WARNING: Use caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. We are not responsible for damage if there is any modification of the batteries/chargers in any form or shape (including pack making). We are not responsible for any damage caused by misuse or mishandling of Li-Ion batteries and chargers.

Disappointed
February 3, 2016
I have used Nightcore before, along with Klarus, Ultra Fire, and Orbtronic, so i was looking forward to the Nightcore3400Ah. Sadly, I was disappointed. The run time on the Nightcore 3400 is almost 20% shorter than my Klarus or Orbtronics; they are more comparable to my Nightcore 2600Ah. Unfortunately I bought 4 at once, seriously considering returning them.
Pros:
None
Cons:
shorter run time than comparable batteries

Great battery
December 10, 2015
I am running 4 in a TM 16. Long lasting. .
Pros:
LOTS of light between recharges
Cons:
Price is a little $$$. Some other flashlight brands will not fit this 3400mAh 18650, its too fat. No problems in Nitecore models however.

Yellow batteries are good
August 19, 2015
Bought one of these Nitecore batteries last year, buying another one today. The "yellow" battery has lasted better (both in charge and in external durability) than the "red" brand I also have. I use in a Nitecore Explorer Cobra (neutral.)
Pros:
Continues to hold high charge. External durability.
Cons:
A bit expensive.

The Best
August 18, 2015
I go through a couple of these each week as I use two Nitecore HC 50 Headlamps. My vision was compromised this spring and I need a lot of light to do close up work and read. The cost of these batteries will be paid for shortly because I use them so much. They last for a very, very long time considering how much I use them.
Pros:
Long life, easy to recharge.
Cons:
There are none!!

Too Long
July 9, 2015
These batteries are longer than spec for 18650s, by about 1/8 inch. Two of them won't work in my Jetbeam BC40. The 1/4 inch or so of extra length overpowers the springs and the click cap won't work. They work fine in single applications (so far). I have one in my JB BC25 and it's fine, presumably because the springs can compensate for the 1/4 inch. How can they be so far off industry standard size?

I'm currently in the field of security and during the holidays my time is spent outside doing traffic control, all the way into the night where visibility is bleak. I need a high capacity battery and I need it to last for a long time and these babies get the job done. I usually spend up to 8 hours outside and carry a shot gun pouch and my 18650 fits snug inside where shells would usually go. Always be prepared.

NICE BATTERY
May 24, 2015
This battery fits very well in my Nitecore MH20. I like the way it can be recharged with the USB feature or Micro USB source. It only took about an hour to fully charge after removing from the shipping package. Battery life is very long and can hold a full charge well. This replaces (2) CR123s which sell for around $5.00 each in my area. Only through Battery Junction can I find CR123s much cheaper. So, it will only be a short time to recover the $25.00 Nitecore 18650 price.
Pros:
Long battery life and holds full charge well. Also, fits nicely in the Nitecore MH20.
Cons:
None

Good battery, limited use
March 31, 2015
These batteries are slightly larger than the standard 18650, so if you're trying to use them in something other than a Nitecore light, you may be disappointed. They do have good mAh ratings, but the size can be problematic. In Nitecore lights they're a good fit, and work well.
Pros:
good power
Cons:
size can be an issue in other than Nitecore lights.

Expensive, but holds a charge
March 26, 2015
Using these batteries in a Tiny Monster TM06, want to have them last a week of travel/work so I don't have to bring the charger with me, so far they are working fine, with plenty of power left after a week. I do not use the highest setting on the TM06 unless I need it (I work in manufacturing), so it looks like a charge will get me the week of mixed use I expect.
Pros:
Holds a charge well
Cons:
One of the more expensive batteries

Battery size
January 11, 2015
The power of the battery is not in question however the power is of no use if the battery will not fit into the flashlight.. The diameter of the battery is not consistent I e some of the batteries sill not fit into the flashlight as they are oversized. and wedge very tightly., Nightcore needs to improve the quality control on their battery production line.
Pros:
good power and longevity.
Cons:
some batteries do not fit lights properly.

Lots of power
January 5, 2015
While the battery is arguably not the smallest around, it does pack a good bit of energy. I was skeptical of the 3400mAh capacity as most numbers seem to only be under "optimal conditions" or "theoretical" but this battery delivers. While I have only had these batteries for the last few weeks so far they are awesome much better than expected. Easily surpasses my disposable CR123, SR123, and previous 18650 batteries capacities. Fits great in my Nitecore flashlights, doesn't fit into surefire lights (diameter too wide). For my every day items like my head lamp, flash light, and bike light it is nice to have a fully charged battery every day that will keep up with me and no need to swap out. I was going through packs of batteries or swapping other rechargeables left and right, but no more.
Pros:
High power density Last a long time Quality construction Rechargeable
Cons:
Price is a little high but easily recovered quickly if replacing disposables

Highest Current 18650 battery exceeds expectations

I ordered 4 of these 18650 3.7 Volt 3,400 mAh batteries to power my new TM26. They charge consistently and provide the maximum power, while offering protection. I highly recommend these batteries!

Warning on Size
January 2, 2015
These are very, very large cells--not 18 x 65.0, but more like 18.5 x 69.5 length. (Yes: 4 mm over the standard). They just barely fit into my ZL H600 Mk II. It takes a little effort to slide it in, and I have to smack one hand against the other in order to dislodge it to get it out. This is okay, provided that I am not permanently deforming the end-springs. But they do not fit, at all, into my Ultrafire WF-139 charger, which has been my standard charger for 18650s for years now. There is no way to force them in without damage to cells or charger. Just won't fit. Luckily, I also have an Xtar MP1S charger that runs off a USB source and it accepts these cells, but it charges more slowly, and only one cell at a time. As far as the cells go, I can't tell you much yet--I hope they will work out just fine for powering lights. But the size issue is a real problem.
