Nitecore 18650 3.7V 3400mAh Li-ion Battery (NL189)

NL189 18650

3.7V 3400mAh

Nitecore has finally made their way to the battery party by offering their own batteries. These rechargeable 18650 batteries are perfect for high drain devices such as the intense LED flashlights from Nitecore, video game consoles, appliances, and more. The 18650 cells are protected from overcharging and discharging, so they can last you a long time. Being able to recharge the cells more than 500 times ensures you'll have power for all of your devices.

Safety First

You are Covered

The 18650 batteries are equipped at both ends with a nickel-plated S.S. protector ensuring high impact resistance, good electrical conductivity and oxidation resistance. To prevent against abrasion the cells are coated with a durable metallic film, as well as the circuit board being coated with tough plastic. The innovative anode was designed to resist high temperatures, while the microporous barrier protects the delicate internal components.

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.
good power
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.
Holds a charge well
One of the more expensive batteries

Lasts a long time

I do not have much history with this battery just yet but I am impressed with the battery life so far. If its longevity matches its performance, it will be at the top of my list for repurchase.

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.
good power and longevity.
some batteries do not fit lights properly.

Nitecore 18650 3.7 3400

Just got them (2) and put them on the charger. Took about 6 hours to charge. Have not really used them on my AR, but what little I did they worked fine.

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.
High power density Last a long time Quality construction Rechargeable
Price is a little high but easily recovered quickly if replacing disposables

Highest Current 18650 battery exceeds expectations
January 4, 2015
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.

$24.95 for 1 battery!
November 20, 2014
I am new to this site and most everything about high end flashlights and batteries. Not too long ago I would have never paid that much for 1 battery. When I started learning about rechargables and lumens, I realized I would actually save $ and get better performance if I put up more $ at the start. I went for the highest mAh that nitecore had (it was only a few more dollars than the next one down). I paired it to the Nitecore i2 charger and away we went! So far, so good. Time will tell.

One of the most powerful, intelligent 18650s you can buy
September 8, 2014
When getting hooked on Nitecore flashlights, I did lots of research on the best 18650 rechargeable Li-ion battery. While there were some esoteric (read: more expensive) batteries with slightly better voltage fall-off characteristics, the best bang for the buck was the top-of-Nitecore's-line NL189. With 3400mAh and an integrated battery discharge/overcharge protection circuit, this is a very resilient, very powerful, and very safe battery for use in an EDC (Every Day Carry) flashlight.
* 3400mAh strong. * Nitecore trusted name. * Uses two high-power MOS-FEE current regulation modules for discharge/overcharge protection.
* This is a "fatty", being just a hair thicker than some other 18650s. Make sure it fits in your flashlight (FYI, it fits in all Nitecore flashlights).
