Detailed overview: Nitecore 14500 USB-C battery 1100 mAh
The Nitecore NL1411R uses the 14500 format, the size of a standard AA cell, with an unusually high 1100 mAh capacity for this cell size, and a USB-C charging port built directly under its protective cap. A simple USB-C cable, plugged into the wall, a computer or a power bank, is enough to recharge it, with no dedicated charger to carry.
One essential point to understand before buying: while the 14500 has essentially the dimensions of an AA cell (0.57 in (14.5 mm) diameter, 1.98 in (50.3 mm) long), it delivers a nominal voltage of 3.6 to 3.7V, against 1.5V for an alkaline AA or 1.2V for a rechargeable NiMH AA. It is therefore NOT interchangeable with standard AA batteries in just any device: only devices explicitly rated for 14500 (generally high-end compact flashlights) can safely accept it.
In flashlights designed for this format, the 14500 allows for noticeably more powerful light output than with standard AA cells, as the higher voltage supports much brighter LEDs. The NL1411R supports a continuous discharge of up to 3A, plenty for compact flashlights of this format, and packs a complete protection circuit (PCB) against overcharge, over-discharge and short circuits, paired with a pressure relief valve and nickel-plated stainless steel connectors.
Rated for more than 500 charge and discharge cycles, the NL1411R suits compact flashlight users looking to move on from disposable AA cells while gaining light output, with the recharging simplicity of a single USB-C cable.

Our tester's review: Pierre Freysinger
Used in a small EDC flashlight designed for the 14500 format, the NL1411R clearly changes the game against a standard AA cell: the beam climbs noticeably in power, the difference is visible from the first switch-on. The built-in USB-C port is a genuine plus for this kind of format, often recharged in small quantities, no need to dig out a dedicated charger for a single cell. The rated 1100 mAh holds up for moderate daily use. The one thing to never forget: it does NOT replace an AA cell in a device not designed for 14500, at the risk of damaging it with its higher voltage, an easy mix-up given the similar size. For a compatible EDC flashlight, it's an excellent modern rechargeable alternative.
Frequently asked questions: Nitecore 14500 USB-C battery 1100 mAh
No, especially not in a device not designed for it: the 14500 is AA-sized but delivers 3.6V versus 1.5V, which can damage an incompatible device. Only use it in flashlights explicitly rated for 14500.
Yes, a USB-C port is built directly under the cell's cap. A standard USB-C cable is enough to fully recharge it, with no dedicated charger to carry.
Its higher voltage (3.6V versus 1.5V) lets compatible flashlights drive much more powerful LEDs, for a noticeably brighter beam than with standard AA cells.
Nitecore rates it for more than 500 full charge and discharge cycles, in line with market standards for a protected Li-ion cell.
