Taken 3.7V 18650 Rechargeable Batteries 3000mAh 2 Pack Lithium Battery Button Top for Flashlights, Headlamps, Doorbells, Toys

These rechargeable batteries are a cost-effective and eco-friendly alternative to disposable batteries. They offer a good capacity and reliable performance, making them suitable for a wide range of devices. The button-top design is convenient for many devices, and the rechargeable nature reduces waste and saves money. However, it's important to ensure that the device you're using is compatible with these batteries and to follow the manufacturer's instructions for safe charging and use.

Hopefully these last! So far they last far longer than the 18650 battery included in our flashlight. The flashlight's battery was "3600 mAh", but last for only 3 hours. One of these Taken are rated at "3000 mAh" and last over 8 hours which is pretty impressive! I'll update if that changes as it seems plenty of batteries out there blatantly lie about their capacity...

Our home is located along the Utah/ Idaho border. Our front yard faces north and it receives no direct sunlight from the end of October to the first part of April. This makes powering our solar lights a routine where I’m always recharging batteries to put in my lamps. We purchased two new lanterns to hang on a shepherds hook. They came with 18650 1800 mAh batteries which would last two days before needing to be charged up on one of my chargers. These batteries give me 7 to 10 days of light before needing to be charged. Additionally, they charge reasonably fast. We’ll see how they do when the temperatures gets below zero in December and January. Additionally, we’ll see how durable these batteries are. If anything unusual presents, I’ll update my review. In the meantime, I highly recommend them.

Not any better than 8 year old batteries in our outdoor solar lights. Replaced in one light that the battery leaked (so had to be changed). And one other (of 4 total) to see if the better than the other 2 with original batteries. The originals said 2,200 mh, these 3,000.

Bought these for a solar security light with motion detector, which came with two 1200mAh batteries for keeping the unit charged through a solar panel, and the batteries would be depleted after a couple of days and would need to be put in a charger to recharge them.After replacing those batteries with these Taken 3000mAh batteries and topping them off a couple of times in my charger, now it has been a couple of months in all kinds of weather, and the batteries are staying charged, and my lights work great.I have used many different 18650 battery brands in the past for things, and these batteries are so much better than any of them.At this point I will never buy any other 18650 batteries. As these are the best there is, as far as I am concerned.

Refreshing to get a battery that performs to the advertised specifications and label description. Rating is 3000 mah. First charge out of the box (at 1000 ma) was 2979 mah and 3084 mah. Also the weight was 45.3 g and 45.5 g. From what I've seen, heavier batteries exhibit higher capacities. Don't believe ratings of 9900 mah. Even 5000 mah is a stretch. I just returned 4 batteries rated at 5000 mah but only charged to 1400-1500 mah (<30% of rating) after 4 charging/discharge cycles.

This item is not as described. I started to charge monthly as described, and now they don't work at all as I am going to have to make another purchase for my upcoming camping with the kids.

I used this product for a remote control car transmitter that I use for an hour at a time quite often. The transmitter has a voltage readout and I can say the capacity on these is great. I’ve been using them for a month and it’s only dropped .3v, still haven’t needed to charge it.They seem well made and worth the price which is a great deal compared to other competitors. Overall if I needed to buy again I would definitely come back to these.
