Customer Reviews
Overall rating: 4.8 / 5 from 171 reviews.
Used to rebuild a notebook battery pack. It's my first time using this type of battery, time will tell, but so far working much better than expected!
I have tested the capacity in 4 out of ten that I purchased and already one came back at 2500ah capacity. The other 3 were around 3000ah. I guess I will have to test all to find ones that will balance out.
Really like these batteries and at a great price!
Works perfectly, capacity is just as advertised. Would buy again!
So far, so good. However, all of the six cells I purchased failed to reach their 3200 mAH rated capacity when charge/discharge cycled by an Ambient Weather BC-3000 charger. The charge/discharge rate was 200 mA, which is 0.0625C of the advertised capacity. The BC-3000 showed all the batteries as having a capacity between 3050 mAH and 3150 mAH.
Although the post office seemed to have an issue delivering on time, the batteries I ordered arrived undamaged. They charged without any issues and are working as expected in my RC transmitter. Overall, a good experience with the 18650 Battery Store!
Excelente Calidad

Awesome price fast delivery
Arrived in a timely manner, proactively packaged. Cell work great.
Great batteries. True to capacity. Quick shipping. Fair prices
Very good
Cells matched specs.
Entrega rápida, las baterías se ven de buena calidad
Using in a 1S4P configuration for a low draw mesh repeater. Ordered 6, and all came in at the exact same V.
These are top notch cells. I'm still trying to collect data and run some more robust diagnostics, but so far every cell has performed as specified (or better)!
Great capacity and price
Solid batteries. Expected them to hold a charge a bit longer than what they do, but still an excellent battery
Great price. Batteries came with my device and it's always good to have spares.
Just what I wanted
They are just like my factory batteries
Great brand of battery and works good too. Recommend this brand to anyone that needs a good replacement battery.
Great batteries long lasting excellent, Great price fast shipping will order again from this company when needed again,
They take a lot longer to charge then the batteries I bought from my local vape shop, but they also last long enough that it isn't an issue to swap out with a fully charged pair.
Thank for fast delivery.
Exactly what I ordered, in good packaging, and good price
These are the real deal, no fakes or aftermarket overly rated weak junk. In testing these they always come out with higher capacity than advertised.
I don't buy much batteries but I was making a smaller ebike 36v power pack and few small 12v packs. Did some research and read INR batteries are the way to go. Batteries from here are the best and actually legit. Bought few fake/knockoffs from other places so highly recommend from this supplier.
Good batteries. Great price.
Great price, fast shipping
Super
good transaction
They worked great for rebuilding my battery pack.
Very happy with my experience, the product, and shipping. I've made another purchase and expect the same outcome. If so, they will be my go to for all my needs moving forward.
Ran a NOR battery test. mah numbers were to spec. Didn't check current output.
I bought these to build a battery block to provide battery backup for an amateur radio. They are functioning perfectly wired in parallel.
I’m rebuilding a Hubsan zino mini Pro battery for the drone. Been in electronics For a very long time as well as extra class Ham. I’m pretty close to being done but would recommend this for a novice operator In the drone hobby. Lots of patience and knowledge needed to have it work. Respectfully Edk/n0ek
