"Works well"
"I needed a couple replacement 21700 batteries for my Nitecore MH12S. BatteryJunction. com is the place to go! Great selection of batteries, and great prices too!"
"I have ordered several of these batteries for my Nitecore MH12-S flashlight and was blown away with the power and runtime. The Nitecore NL2150 21700 5000mAh 3. 6V Batteries are just perfect for the job. I keep several as backups ready to go for quick change out even though I can charge the light directly, I don't. I do use a charger for the batteries. Nice to have options though. These batteries are a great example of another quality made item from Nitecore and give great piece of mind that you won't be left in the dark when you need it most."
"The Nitecore NL2150 is the chosen battery for my high end underwater video lights. They are long lasting and high quality. There really isn't another choice when it comes to adding a backup set of batteries for these particular video lights."
"High quality, heavy duty battery. Runs my MH25 very well."
"This battery can only handle an 8A continuous output current. Almost any 21700 can do that for less money. I would suggest that users look at the Acebeam 21700 on this site for the same price, but also doubles as a portable charger with it's USB Input/Output port. Moreover, at least it offers a full 20A output current. Nitecore is charging double of what they should be for this one. . ."
"After using my machete to open the package it looked rather nicely made (in China). This is a 5000mAh cell rated at 8A, the minimum required for the Nitecore MH12S I also bought. This is a protected cell. If you're looking for a nice recharger for these (besides the flashlights built-in one) I recommend the Xtar X2 (extended model). The extended model is a few millimeters longer to handle the protected 21700s extra length. The X2 will do 1A and 2A(single cell only) recharges. Check it out."
"Arrived once I finally got the product packaging open (the plastic sealed packaging is a pain in the keester to open) it charged up just fine and is in service. Great product as are all nitecore products."
"Nice wrapped battery the best quality as expected from nitecore"
"Bought it for my New P12 and has great run time. Good quality packaging on the battery."
