Fenix ARB-L14-1600U 1. 5V USB Rechargeable Li-ion AA Battery

"Hi sorry for the late review for met recent order of Fenix ARB-L14-1600U 1. 5V USB Rechargeable Li-ion AA Batteries. I need to actually order about 10 more. One thing that would make this perfect is a multi unit battery charger. It does take a while to recharge with a single micro usb charging cable. As far as the quality of battery, they are great. I will be ordering another 10 batteries soon again. We now because if sad FAA regulations must wait a significant longer time then normal. I am currently retired so they seem to take for ever to arrive. No worries. Chrispen G. Florida 🙏⚡️"

14-500 1.5 volt rechargable battery review

"portability and ease of charging with light monitor indicating full charge."

— Ron M. (5/5)

Better Rechargeables than NiMH batteries.

"I am very pleased with these Fenix brand Rechargeable Lithium 1.5V DC Batteries. They work well as an alternative to disposable alkaline cells. I already had Rechargeable NiMH batteries but they only charge up to 1.2V DC. And for some of my devices, these 1.2V NiMH just do not work. I have not yet had the Fenix batteries long enough to see how long-lasting these Lithium batteries are. I hope for at least one year."

New & Helpful but…

"Well, I just evaluated these new rechargeable 1.5V li-ion cells and I'm a tad disappointed by their capacity. On a ZTS model MBT-1 pulse load battery tester (a "high end" instrument), a freshly charged ARB-L14-1600U cell will readily pass the AA alkaline cell load test, but clearly fails the more stringent load test intended for Energizer L91 type non-rechargeable lithium iron disulfide (LiFeS2) FR6 type AA cells. So confine these new 1.5V rechargeable li-ion cells to moderate drain applications, and expect to recharge them about as often as you'd replace an ordinary alkaline AA cell."

working good

"I have only had this product for a short time. I have charged four times so far and it charges fast and everything seems to be working just as they advertise. Good product I will probably buy more."
