Excellent service

I placed my order on line for a special battery.  I needed one immediately, but realized that could not happen.  I was surely surprised to see how quickly Nitecore shipped my order.  It arrived in record time and was greatly appreciated.  Thank you!

Nitecore Nitebattery

Purchased the battery as an experiment to replace a Ring Solar Pathlight battery.  It works flawlessly but am reserving final judgement for a couple months since thats about how ling the Ring Batteries last.  I found the Nitecore batteries by reading a blog about the Ring batteries. I think Nitecore may have a definite market as replacements for the Ring Battery.

Batteries

What can you say about batteries that have yet to be used.  Shipment was as declared, no problems, right  items were shipped, happy as a clam.

Wrong battery

Couldn't tell from photos whether or not battery was flat on both ends. It was not & didn't work in my flashlight. Not sure if return is possible  Nitecore has yet to indicate if I can return to the battery even though we have discussed which battery might work in my flashlight

Best quality

I've been using Nitecore flashlight for over a decade now. I still use my original NL1834 battery that came with my first Nitecore flashlight. Nitecore has outlasted all other brands of rechargeable 18650 batterys I've tried. And now the only 18650 battery I trust is Nitecore. And shipping was great ordered on. Thursday and received my order on the following Monday. And I love the no shipping fee over 35 dollars. Nitecore you've earned a life long customer. Thank you.

Great Batteries

I have used this battery in my old headlamp for about seven years till I had to replace it. Got many hours of use out of it. Saved me a lot of money over disposable batteries.

Fast shipping

I bought these to replace my  5 year old rechargeable batteries that have served me well. I expect these new Nitecores will be just as good. Oh, and fast shipping too.

Long lasting

I use it, and recharge it every night in my headlamp. The last two NL1834 batteries lasted well over 500 cycles.

Rechargeable batteries and a TINI2 flashlight.

So far both times I've ordered from Nitecore my products have shipped in a timely matter and confirmation was immediate. Great products and I will be ordering from them in the future.
