The last bullet is almost the most important. The prices aren’t much different than standard batteries!.The capacities of the cells well-exceed today’s technology.The “brand-name” can vary in the way it’s written.The labels come in a variety of different colors and styles.But it’s this inconsistency that SHOULD be a red flag! But traditionally, Ultrafire is NOT a trustworthy brand, and the fakes are everywhere! Quality varies alot. And if you should somehow get a genuine Ultrafire battery, it might just be what it claims. Now, I will admit, that if you search for reviews of Ultrafire 18650 batteries on Amazon, you’ll get a wide range of opinions. Barnum as once quipping “there’s a sucker born every minute” the fact remains that even with all the information available today (such as this website) there are those who are just in too much of a hurry to buy something without doing the necessary research first.
“Caveat Emptor”Įven though history (perhaps inaccurately) cites P.T. Get the picture? Even in today’s world, it’s not uncommon to find some 18650’s being marketed at 5000 mAh!!! This is because the current technology is getting close to producing 4000 mAh cells. What should be a 3000 mAh cell, is now a 3400 mAh cell. As an example, a 2600 mAh battery becomes 3000 mAh. In order to sell more batteries (and hopefully impress the consumer) these no-name manufacturers use an existing name (in this case Ultrafire) and purposely inflate the capacity two to three times above what the current technology allows. For one thing, the capacity of the uncovered cell in the photo, is probably around 500 mAh, maximum! It’s important that when you’re shopping for 18650 batteries, that you research what the CURRENT capacities are in today’s marketplace.Īs of this article date (to give you an example) the top capacity on a quality 18650 battery is about 3400 mAh (milliamp-hours). In this case, the label reads “4200 mAh”. But in addition to it NOT being a 18650 in the first place, they also routinely misrepresent the capacities as well. Obviously in the extreme case above, they’ve gone so far as to lie about the size of the cell they’ve so carefully wrapped. This is where the manufacturer gleefully attempts to pull the wool over the eyes of the unsuspecting consumer. But look at what the circuit is attached to! It’s a blue battery that appears to be nothing more than a 16340 rechargeable cell, placed INSIDE the large tube PRETENDING to be a much larger 18650! This is outrageous! Those Labels (often) LIE! This initially was the battery’s protection circuit (the attached disc on the right). The battery in tact, is what the silvery object on the left originally resembled.Īfter peeling off the label, they ripped off the top of the cell. What you see in the photo is what a consumer found after disassembling an Ultrafire 18650 battery that they’d purchased online. Fake 18650 photo courtesy of Budget Light Forum
