Nitecore rechargeable 18650 batteries.

I',m very happy with the NL1834R batteries. The micro-USB batteries are the perfect upgrade for my old faithful SRT9 flashlight.

Quality durable equipment

Nitecore is my go-to lighting system for my outdoor night shift work. I work in all elements and temperatures/extreme environments as a line mechanic on commercial aircraft, my Nitecore headlamp and flashlight take the beating with me and more, but keep on working reliably! I love my Nitecore lighting equipment.

good batteries

so far the batteries work great--as expected. Shipping was a little slow, but since it was free I can't complain about that.

Top notch gear

Love these batteries solely for the fact I can use existing cables to charge, and, if you want to charging stations. Great looking and fast charging in my opinion. Great bang for your buck.

Awesome products and Great customer service!

I have been using Nitecore products for year's and have never had any need for customer service. Until just recently I had a battery that would not charge. I sent a note to customer service and almost before I could set my phone down I received a response from a Mr. Wyatt C. Not only was it a real life person and not an automated response but he was also kind, courteous and quick to get me a replacement in the mail immediately. Thank you Wyatt C. and Nitecor you have earned a lifetime customer!

1860 Battery

I purchased a rechargeable USB C rechargeable 1860 battery and it's a great battery that recharges without the need for a charger! Easy checkout and quick ship!.

Your battery is too large to fit in my Surefire flashlight. So it was never used because it was useless to me. Returned it and that cost me 11 bucks out of pocket. Still havent received my return.

Little bit bigger in reality

True length is about 70,5 mm, diameter 18,5 mm and at ten + side with micro USB even up to 18,8 mmâ?¦ So it will not fit wherever it should according to the declared dimensions.

Customer service was pretty bad

The person who answers the phone, I won?t say his name for now, is rude and incredibly unhelpful.  It?s really a shame.

Great Battery w/ Convenient USB charging port.

Nitecore and "a few" other top brands cannot chance their reputation on junk batteries from unknown sources.  This battery is top quality with great output time, thermal protection and the convenience of USB charging without being in the device.  You get what you pay for and the difference in price is not that much for what you get.  Nitecore also offered a nice discount code.

I love all of your products. High quality. Only thing I wish you would change is all lights charge using type C Charger. Keep up the good work!

no charger

At least initially charged up and lit up my flashlight. Have to wait and see if it stands the test of time and use/abuse. Hope this frees me from needing a special charger on the road and awya from home.

for longer use. I own a couple of these and like the built in charging port. They have a larger milliamp rating

Excellent Service

The Nitecorestore always processes and ships my orders promptly. I have  several of these batteries and they have performed well while giving the charging capability built-in. I have spares as backup and they hold a charge for some time.

Great battery

This battery outperforms others. I use it in photographic equipment not flashlights. I have really enjoyed not having to have any specific charger as there’s a charging port in the battery itself which is fantastic. Lasts long, charges quicker than others I’ve used and looks great. I will be buying more as I need them.

Works like it should.

Great product.  Bought the battery for a flashlight for back country use.  This battery replaced 2 smaller batteries.  I don’t need to carry multiple batteries anymore and can charge with my portable battery backup if it happens to run out of juice.

Nitecore rechargeable 18650 batteries.

By C P.

I',m very happy with the NL1834R batteries. The micro-USB batteries are the perfect upgrade for my old faithful SRT9 flashlight.

The new Nitecore NL1834R 18650 battery is a revolutionary battery designed with a built-in micro-USB charging port making charging easier than ever! No more need for an extra charger as this battery can be charged directly using a standard micro-USB charging cable (sold separately). Simply plug the battery into an available power source and a red indicator light under the + pole (positive) will turn green upon completion. Alternatively, these batteries can still be charged on an external charger if desired.

The NL1834R batteries are designed for powering high drain devices such as high-output flashlights, lanterns, headlamps and bike lights, as well as a variety of other appliances and devices. With built in smart charging circuitry and other integrated safety features through-out, this battery will safely work in the majority of button-top compatible devices.

Nitecore NL1834R Features

  • Red & Green charging indicator LED's
  • Microporous barrier and pressure release valves help protect the battery and prevent damage caused by rapid expansion & combustion
