High Capacity 18650 Rechargeable Li ion Batteries with PCB 18650 3000mAh button top PCB protected rechargeable lithium ion batteries are ideal for use in flashlights and other devices. Batteries provide much more recharging life cycles than cheap UltraFire Batteries. Batteries WILL NOT WORK IN VAPE DEVICES such as vape mods products. Vaping devices REQUIRE hi-drain FLAT-TOP Li-ion batteries. Li-ion batteries without a protection circuit can potentially cause a fire or explosion. The EcoGear FX 18650 3000mAh batteries HAVE an integrated PCB protection circuit. Features and Benefits: Integrated PCB protection (Helps prevent Anti-Overcharge, Anti-Overdischarge, Anti-Short Circuit) Manufactured under ISO9001-2000 to assure quality Battery Specifications: Capacity: Nominal: 3000mAh, Minimum: 2600 mAh Internal PCB protection prevents under-voltage at 2.5V and over-voltage at 4.25V Nominal Voltage: Average 3.7V Cut-off Voltage: 2.5V Cycle Performance: 90% of initial capacity at 400 cycles Cycle life: > 500 cycles Charge: Current = 0.5C (~1500mA) Voltage = 4.2 V End Current = 0.01 mA Discharge: Current = 0.5C (~1500mA) End Voltage = 3.0V Battery Length: 69mm (2.72 inches) NOT for Vape Products ONLY Recommended for LED Flashlights

Capacity is not as advertised
Bought 2 sets of two batteries and all of them are ~10% less than advertised.I did three cycles of discharge and recharge (for lithium, normally we do not need to do this to get the real capacity, unlike NiMH batteries) and starting from the very first cycle, all of the batteries are hovering around 2700 mAh; instead of the advertised 3000 mAh. I tested this using 300 mAh charge current; hoping that charging with lower current will get the batteries to store more capacity and it is not.I thought that this is going to be the winner, at $9.99/2 batteries, this is a real winner in terms of price. Batteries from other more reputable brands (Nitecore, Thrunite, etc.) are selling at at least 3 times than this per 2 batteries. But they offer true capacity to the advertised value. I owned couple of Nitecores and they are all tested slightly above the rated 3400 mAh.If you do not care about the capacity being 10% lower than advertised, then get this since it is the cheapest at the moment I bought them. For me personally, I am returning these batteries because if they lied on the capacity, then what else are they lying?

Works great with Fantasea BlueRay Radiant 1600.
Works well. I use these in a Fantasea BlueRay Radiant 1600 Video light. The Radiants came with Tenergy 2600 mAh button tops. Even when not used at full power, the 2600 Tenergys would only last less than an hour. The 3000 EcoGears went about.65 minutes( mid and high power) and still did not give me the low power warning. They are about all I need for dive video. If you are one of those 90 minute divers, you'll probably need more mAhs. The package says PCB, but it is not marked on the battery.Things I learned about 18650 batteries. Know what you device takes. Button top vs. flat top. PCB vs non PCB. Just buy one set and see if it works with your device, before ordering more. If you wind up with multiple sets of 18650s, get some battery cases to keep them organized.

Not 3000mAh batteries, still fake, but they will do for now
How can these companies put 3000 mAh on the side of these batteries, yet, NONE OF THEM reach the rated 3000 mAh.I dare ANYONE to buy these and get 3000mAh out of them. The description says 3000 nominal, and 2200mAh minimum. I would say these are 2200mAh and highs at 2550mAh. See attached pic. That's the second charge and refresh on these via my OPUS BT-C3100 charger. These batteries are still too expensive at that rating. I think 8 bucks a pair is realistic price for these, as they are NOT 3000mAh batteries. You can buy a 1200mAh portable battery pack for less than these batteries, and that's what I'll do next time.

Is larger than the same model# battery of other makers
Bought these and they did not fit in the flashlight that had another batteries of the same spec. This one is just a little larger and would not work.

Good price for the product
They charge. How long they will hold a charge, undetermined as I just received them. They fit the flashlight for which they were purchased.

Would not recommend for a high powered headlamp but for anything else ...
Lasts a long timewhen used in short bursts. Would not recommend for a high powered headlamp but for anything else they are perfect.
