14500 Rechargeable Battery 2500mAh 3.7V Li-ion Batteries Button Top 4 Pack for Headlamp Flashlight

If you need these, these batteries are a good option.Till now, I had a hard time finding 14500 3.7 volt batteries for my flashlight. My NICRON N7 LED flashlight can use regular 1.2 volt AA batteries but if you can find them, it lights up far brighter with 3.7 volt 14500s.These batteries work well and so far, appear to provide solid decent service for both my flashlight and my radio that takes this size battery. These are a good value and I feel I got exactly what i wanted and what I paid for. They are easily and fully charged in my 5 year old battery charger. However, lucky for me, that charger was made and sold as a universal Smart Charger for rechargeable batteries Ni-MH Ni-Cd AA AAA C Li-ion, 18650 14500 16340 18500. If you have a similar smart charger you are golden. Otherwise, you may have to upgrade your charger if you have a "dumb" standard AA Ni-Cad or NiMH unit. There are lots available on Amazon.Please be warned, these batteries are the same size and shape as regular AA batteries. You do not want to put them in or expect them to charge in any device that is not made to handle the triple (3x) voltage power these batteries put out. I am happy. I hope you will be too. Just know what you are buying and what to do with them when you get 'em.

I bought these for the guys in my band to use in their in ear monitors. They have saved so much money on batteries, and these last through every show.

These are garbage. They claim 2500mAh but they are closer to 250mAh. They would not last more than 2 hours in my headlamp, whereas my old 750 mAh batteries would usually last 8+ hours. To make it worse, within 2 weeks 2 of the batteries refused to accept a charge. Don't buy this junk.

I only need one battery in my soap dispenser. I soldered it in, charged it and it has gone a couple of weeks, so far, on the same charge

Fast delivery! Holds charge!

Excellent batteries!

These cells were tested using a .5C and 1C method on an ATORCH DL24 battery capacity tester.Their capacity’s ranged from 331 - 389mAh, over 80% less than the advertised 2500mAh.14500 cells with 2500mAh capacity are uncommon: The typical capacity for 14500 cells is significantly lower (around 700-800mAh). A 2500mAh capacity in this size might be unrealistic or indicative of mislabeled cells.Even assuming 800mAh these cells don’t even deliver half the capacity they should.At best they have an issue with manufacturing, but this seems like fraud.

Ok
