18650 Button-Top Rechargeable Batteries PCB Protected Best for Flashlights
High powered 18650 lithium flashlight batteries offering 3000mAh of reliable power. The EcoGear FX 18650 button top lithium-ion rechargeable batteries are unique and are packed with an amazingly amount of powerful energy. This is our best 18650 battery as it provides dramatically increased longevity, low self-discharge, efficiency and optimized usage time. The choice battery for LED tactical flashlights and battery-powered professional gear.
When you think of batteries, what might come to mind is what you have seen in most in the store aisles. There is the widely used AA or AAA alkaline size batteries. However, alkaline batteries are old out-dated technology and cannot match the power of lithium-ion batteries. These 18650 PCB lithium flashlight batteries deliver the power needed and offer up to 500 charging cycles.
The 18650 button top battery is the best for using in LED flashlights, video doorbells, camping lanterns, indoor fans, portable radios, bluetooth speakers, work lights, motion lights, cordless power tools, solar yard lights and many other low drain devices. Lithium rechargeable batteries are also used in aerospace technologies applications (radio-controlled models, model aircraft, the Mars Curiosity rover, etc.). The 18650 PCB battery is protected with a small built-in electronic circuit which prevents overcharging and over-discharging.

These are the same lithium-ion batteries which were once top-selling on Amazon. Unfortunately, Amazon no longer allows the sale of many types of lithium-ion batteries including 18650 batteries. These batteries are NOT recommended for high-drain devices (i.e. Vaping Products). Sold as a 2-pack or available at wholesale bulk pricing.

We had a rush to get batteries for our recording equipment during a production, so I tried these, and they worked excellent! The protect circuit board feature was important to us for added protection.
The 18650 batteries were great and we could tell from the amount of use we put on them that there was a ton of life still in them at the end of show. In comparison to past battery experiences, these batteries are good, long lasting batteries. I would definitely purchase again especially for the great price!

I certainly wouldn’t want to pay more money for a battery that does the same thing but just isn’t “trending” if that makes sense. These seem to generally have the same capacity if not a stronger amount than that of the other competitors for 18650 batteries. When batteries are this good of a deal, you will find yourself wanting to use them more frequently than other batteries on the market. They offer plenty of time for usage and for the price you really can’t complain.

I use several 18650 PCB batteries regularly to power a variety of tools I use around the house, including my wireless ring doorbell. I have never had the any problems with any of the batteries I have purchased and have been satisfied with how long they last. Before I use some of the batteries, I test the percentage of charge it holds. So far, I have never had a battery that did not register either strong or excellent before first use.

When I first received these batteries, I gave them a complete charge. I have the Ecogear battery charger so they charged rather quickly. So far they seem to last a long time and I have recharged them several times. I like the battery colors as it makes it easier to find in my battery drawer.

One thing I am not is a battery snob, but I do love to save $$$$. These 18650 lithium batteries come well packaged and have a nice logo. Even if the batteries didn’t have a nice logo, why would it matter it will be hidden inside the item you’re using. After I charged them they last a longtime and their better priced then other 18650 batteries. What’s not to love about that?

We use these batteries in our ring doorbell and flashlights that we use frequently. These batteries are homeruns. They work well and we are switching to the Ecogear brand batteries as they offer just as much quality than the name brands do.

These 18650 pcb batteries are reliable and are great batteries for the price, you get more for your money. I intended to buy more of these as a reserve to use when charging my current batteries. Now I feel more drawn to use these batteries on a more consistent basis.
When I first received the batteries they were charged around 30 percent. Maybe this was done for safety but they did completely charge. I will personally buy several more boxes to keep in the cabinet for emergency situations.

I have a high lumen LED flashlight and these batteries seem to drain a bit fast. Right now, I’m getting at most, 4 weeks of usage. And every once in a while, they seem to only last 3 weeks. If you need an average 18650 battery at a good price, then I guess this battery could be useful.

I have been using these 18650 batteries for a while now, and they are great! Their lifetime between charging is better than I expected and I got them at a great price. We use them in our household items such as flashlights and camping lanterns, without any complaints. For the price and the convenience of having them shipped to your door, you can’t beat them!

These are in many ways as good as other big brand names on the market — we use them in items that get used sometimes and, in all cases, these are home runs. No quality control issues or anything of that sort and these batteries are a great price for the battery usage you can gain from them. I would recommend them to people reconsidering an alternative from other name brands on the market.

I purchased the “EcoGear FX TK130 Kit” a couple years ago (includes the larger TK130 and smaller E300 flashlights. The TK130 uses the 18650 PCB 3000mAh Lithium-ion Button-Top Battery, and the Kit comes with two rechargeable batteries. The TK130 is perfect for home, car, and emergency light. I also had another similar flashlight, so I decided to purchase another two-pack of 18650 PCB 3000mAh Lithium-ion Button-Top Batteries directly from EcoGear, and they came within a week. The cost was very reasonable for great rechargeable batteries. And I knew that buying EcoGear batteries for their own flashlight was a good was to insure the right fit. They of course do fit perfectly the FX TK130, and they also fit the older non-EcoGear flashlight. Thank you EcoGear for excellent products. I will continue to recommend your flashlights and products to those in my Emergency Preparedness community.

Fantastic!

Not reviewable as new batteries after charging did not solve the weak illumination issue.
