Nitecore NL1834 18650 Battery

3.7V 3400mAh

Incredibly powerful and remarkably safe, the Nitecore NL1834 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 NL1834 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 NL1834 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

Consistently great
December 23, 2016
I've only used a couple of brands of 18650 with my headlamp, and these nitecore 3400mAhn lithium batteries are fantastic. They last SO long! I am not sure if it's the light, the battery, or my imagination, but the light also stays consistently bright almost right up to the time it finally gives out before needing a charge. Sorry this is not more of a technical review, but I'm just an everyday user of a headlamp that I rely on a great deal, and the best I can offer is that I am very, very satisfied with these batteries.
ProsLong, consistent light throughout the span of one charge. The amount of charge, and thus the time between charges is truly remarkable. All around great batteries.
ConsSeems to take a long time to fully charge--but that could be because I am using the device instead of a separate charger. Still, plugging it in at night renders it fully charged by morning.

Long Lasting, High Quality
December 4, 2016
I use these batteries in ALL my flashlights, high quality and fit in the varied flashlights I own. The 3400's last way much longer than the 2600 batteries I used to run and much brighter than the Panasonic 3.6V's I own. Also added bonus of protection gives peace of mind when charging, all this at a great price -even better when they're on sale!
ProsLong lasting, lots of power at 3.7Vs, high quality at a great price
ConsWas sent a battery that had a tear in its wrapper that started to spread, it was immediately replaced by Battery Junction -GREAT customer service!

I have not had time to use this yet, but the size and outside appearance looks good. It took a charge well.

Good for Convoy S2+ and C8+
June 25, 2020
I love warm-tinted high CRI flashlights. Sadly, those can be hard to find. Convoy offers a variety of quality flashlights with lots of choices for LED and color temperature. I decided try the S2+ and the C8+ with SST20 and Nichia emitters. These were my first 18650 flashlights so I needed batteries. I called the good people at Battery Junction and they helped me to pick this battery. I've only been through a few charging cycles but these seem to work very well in both flashlights.

Thanks!

Richard
from SWF asked:
May 22, 2014
Nitecore states it can run on 18650. I see Nitecore has several 18650 rechargeable batteries with different mAh? I know nothing about battery tech. Will the SRT run on all of the nitecore 18650? I suppose the higher the mAh number the better or longer or brighter?
1 Answer
Yes, the SRT5 is compatible with all of the Nitecore 18650 batteries. The mAh refers to the capacity of the battery, which means the higher the mAh, the longer the runtime.

does this come with a charger? If not, which charger would work with it?

This battery does not come with a charger. The Nitecore i2 Charger or Nitecore i4 Charger would be great options to charge Li-ion batteries.
