The 18500 batteries seem to be of a much higher quality than the ones from DXextreme. Also, the prices are not that much higher, and the delivery time is much much better - anything from overseas (especially China) can be months in transit. I haven't had the batteries long enough to really test them out, but as of now, they seem to be a winner.
Mervyn N.
I’ve tested the capacity of both these 18650 lithium ion batteries. The are good, and show a consistent 3400+ mAh. Weighs in at 48g
Brian P.
The battery specs were great and the reviews were good also. Of all the different 18650 batteries I have had and tried, this one is the first one that its OD (outer diameter) was larger than all others that I have owned as I had to "shake" the flashlight to get it out. Possible, the ID of this one flashlight tube may have been out of spec also. (too small)
Todd H.
I have 6 of these for my tactical flashlights and they make my flashlights brighter and keep a charge longer than the 12 other batteries I have. These are super solid batteries.
Kevin T.
I bought the for my flashlight in my bugout bag. I work for Panasonic and was thrilled to find the panasonic brand 18650
Gerardus W.
Works well in a portable radio designed for 18650 cells. This battery lasts almost twice as long as the one that came with the radio.

Excellent battery and seller.

I feel safe with these batteries
Based on 16850 battery store recommendations I went with Panasonic batteries. I had a cheap 18650 battery and cheap charger malfunction and became so hot it melted the plastic wrap. It really scared me. I feel safe with these recommended batteries. What a great store to buy from.

Perfect Purchase!
I bought a Panasonic battery using 18650 battery store for the first time. The battery was great, as advertised. What I was really impressed with was the 18650 store on the purchase. I received the battery in a very timely manner, it was packed perfectly and I received notification and tracking links on each step of the purchase (confirmation, shipped, in transit, and delivered). I'm very impressed by the information on the website and with everything about this store. The packing slip included a checkmark verification from the packer to ensure they shipped what was on the order....I appreciate that. This was a great shopping experience and will definitely use 18650 battery store to buy my 18650s in the future!

Wrong type
I have no doubt that the batteries are good but they do not fit my video doorbell. I need the one without the button on top. Is there a way to exchange what I have for the correct batteries? I purchased six batteries for two video doorbells?

Awesome Product
I needed a quality rechargeable 18650 for a Streamlight duty rifle mounted light and the SL rechargeable batteries don’t work with the pressure switch tail cap installed. This battery works flawlessly and is cheaper than the SL batteries. Will definitely be buying more from here.

Pay close attention to actual size
18650 batteries are not necessarily 18mm x 65.0mm. This is my first time purchasing so-called "18650" batteries and I consulted this website's guide to sizes, which is somewhat helpful. While these NCR batteries perform well, they are much larger in diameter and length than the 18650 batteries they replaced. It is only by cramming these batteries into place that they are useable. If the battery compartment were any smaller, these would not fit. These are a good value, but the designation of "18650B" does not convey the actual size relative to other "18650" batteries, so I got lucky that they can be used.
Shad Patterson
Great so far.
Fast shipping too.

Perfect
The delivery fast the packaging was fine and the batteries came in their own protective box. These were the batteries I was looking for!
Allan Hayes
Great battery
So far so good. running this in a hefty laser pointer and it is super bright! charging took a little longer than i was expecting....about 8 hrs. but that may have been due to some other variable specific to my household or area. Nonetheless, for the price and performance, its hard to beat.
PATRICK STEVENS
Great for my flashlight
I bought these for camping, I’ve run into a few circumstances where I need my bright flashlight for an extended period of time, this battery does the job well.
Ronald Matthews
Too long
I bought these Panasonic batteries for my Tecsun PL-880 radio. With the protection circuit, they are too long to fit into the battery compartment of the radio. Not sure what to do with them now, as I have no other devices that use the 18650.
Unknown
Excellent replacement batteries
Holds a good charge and goes a long way with my flashllights.

Sent the wrong type
They sent me flat tops when I ordered button top. I asked customer service and they asked me to send a picture. I did and haven't had a response.

Great place to purchase batteries
I was impressed with this store. It looks like what you purchase is what you get. I bought some Panasonic 3400's 18650s, and they test equal to the label quoted. The people there were very present to talk too. I will shop with them again.
Matthew Podnar
Great!
Way better than the one that came in my Braun flashlight. Fits perfect twice the run time.

Good Protected Cell
Purchased for use in a Lumintop GT Mini flashlight. The protected cell is a little longer, this is noted in the description. However, cell does work in the light. More peace of mind with the protected cells, and protected cells are recommended for this particular light.

Top grade batteries for a great price. I couldn't be happier with the batteries and this store.

Panasonic NCR 18650B Battery
I don't know much about batteries. I don't have the tools to test the ones I received but after searching youtube and watching the testing done by the battery on numerous 8650 batteries. The Panasonic NCR 18650B were the best for my application and at the best price. Sure you can get better but, I wasn't willing to pay 19.00 for a flashlight battery.
Eduard breuer
great battery
Super fast shipping. Was a bit longer for my application but charged up without issues.
Unknown
Well made
This protected battery appears to be well put together. Works in my Harbor Freight folding work light just fine. Big upgrade over the battery that was included with the flashlight.
Kevin Reed
Be aware of the longer length.
These batteries are a fantastic performer and great bargain. But you need to be aware that they are longer than some battery holders will allow. In most of my lights it's a tight fit, but they work. In other lights it's a no-go. They will break the holder if you try to force them in. Just be warned. That's the only reason for my 4 star rating instead of 5.
KTR
Works fine so far.
Ordered 10 batteries. Did run time tests using same equipment used with other more expensive batteries. The Panasonic batteries ran just as long as the expensive batteries.
John Cozma
Perfect!
Took a loooong time to charge, but once they were topped off, they were perfect!
Unknown
Almost good
Ordered 2 18650 batteries; started to charge them; one said it was good; the other said it was poor doesn't really hold a charge. It's a battery, sometimes you get one that isn't really useful. Considering the price of the battery, it isn't worth trying to send it back. I can just buy another one. I like the company though.
Josh Lepselter
Battery Metal strip
1 of the 4 batteries has the metal strip folded or otherwise thicker than the rest which makes fitment in a flashlight a bit too snug. Possibly able to be repaired, with a new wrap though since the current one needs to be removed
Brandon Kershaw
18650 batteries
Batteries seem to work well but have not used them very much since I’ve only had them for a week. Only question that I have is why is Panasonic’s name not on the battery?

Delivered quickly and came charged
I am a first time customer and ordered rechargeable batteries for a new pocket flashlight that had been difficult to find in local stores. They were delivered ahead of the predicted delivery date, came in their own protective case and arrived charged. I wouldn't hesitate to use 18650 battery store again
Robert Housedorf II
tested OK, not labelled as Panasonic
i bought 4 of these, and they look nice. No mention of the word Panasonic. Ran all 4 through a Hiletgo battery discharge tester, which seems to do an OK job at testing. It is by NO means a pro grade battery testing instrument! https://www.amazon.com/gp/product/B0716ZL1SM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 NOT CURRENTLY available, just for reference. these batteries all came out at 3300 - 3200 which is well within expected results. My Review? For the price, buy what you need for your regular use, keep the set together, and test in your Real World Usage situation. If they work for you, they are a GREAT price at what I paid, $33.57 for 4 , shipping incl.

Name Brand 18650's for Flashlights and Radios
The protected cells from Panasonic tested to spec on start-up and are working well in my low-draw toys. Good choice for replacing the Chinese c#@p that usually ships with this stuff. Definitely not for high-amp loads, but probably safer in this application, and more mAHs. Buy a replacement and a stand-by spare. They ship with a decent safety storage case, so no worries in storing the spare (and the Chinese one).

Battery is fine but too long
I wasn't aware that protected batteries might be physically longer than non-protected ones. Unfortunately, the holder where these batteries were supposed to go would not accommodate these cells.

Purchased wrong battery???
When I purchased these two batteries, I knew I was faced with deciding whether I needed flat or button top batteries. I purchased 2 button tops after examining what I have. Sadly, the new batteries wouldn’t fit.

Outstanding Customer Service
I needed a simple lithium battery for a flashlight. I didn’t know which of the many the Battery Store had in stock. They responded to my email immediately and with a few questions and an email I had the correct battery in a couple of days. They went out of their way for a $5.00 purchase. Greatly appreciated, don’t get the kind of response I did very often. Thanks very much, excellent company with a lot of product in stock.

Better than any 18650s I've ever owned
I bought 16 Panasonic batteries and found one bad one. Apparently the protection circuit would not allow a charge. But the team at the 18650batterystore sent me a new replacement the same day I contacted them. Great store!
Terry O
The right battery, first rattle out of the box
I agonized mire over the correct battery for my flashlight, than the light itself. I based my purchase on reviews I read. Works as advertised, and I am completely satisfied.

Seems fine
Haven’t used yet. Purchased as spares as I have several light that use them. They arrived with about 1/4 charge, but charged up fine. Time will tell.

Carlos Yanez
Don’t know yet
I bought a MF Stingray flash light and ordered 18650 batteries from your company. The flash light uses three 18650 batteries in series and it’s turning off by itself. I called the flashlight manufacturer and they said that it’s caused by poor quality batteries. They say that the battery circuit shuts them off for that application. So I’m ordering batteries from them MF (2.5 times more expensive) to make sure that that’s the case. If it’s not I’ll write a new review.
