Dan K.Good quality. True mah battery. Long lasting Steve L.Work greatBrandon S.I’m sure these are a great product. I got them fast. Fastest delivery ever. However, they are the wrong type of batteries. I thought they where flat tops. Jeremy L.greatJustin J.If you order from this store, they spam you with requests to write a review.Then, when you finally do break down and write a review, they spam you with more requests to upload photos of you using it, which seems a bit silly for a battery.Then, they spam you with requests to describe the “look and feel” of the battery.So, to see where this journey takes me, the following is my description of the “look and feel” of the battery:These batteries look like a regular 18650 battery with a metal bump on top for a positive terminal and a shrink-wrap color that looks like a light green material.The battery feels like you would expect a battery to feel – it feels smooth on the outside of the plastic shrink wrap – its not like sandpaper; they feel rigid, not floppy like a wet noodle.They do not feel sharp like they could cut you open.Surprisingly, if you leave them sit on the kitchen counter overnight, then the next morning they feel like they are about the same temperature as the kitchen counter.The feeling of them is not slimly, so I don’t think that there is a thick coating of oil on them.Oh, and back to the “look” of them – they are not really shiny, so if you look at them in a bright room, its not like someone is flashing a mirror into your eyes – so you can actually look directly at these batteries without having to wear eye protection.I expect that after I submit this, I am going to get an email asking me to review how the batteries smell, taste, and sound.Robert E.Price was excellent, shipping was super fast which is pretty rare during a pandemic unless your business ends in oogle, mazon, pple, etc. My batteries arrived in brand new condition, definitely not re-wrapped, and provide the voltage and capacity advertised. What REALLY surprised me is that they actually came in a hard plastic safety carry case, where every other company I’ve ordered 18650 batteries from, they arrive in individual little cardboard boxes.Definitely not ordering my batteries from anywhere else, ever again. This was by far the best experience I’ve ever had. Thank you so much 18650 battery store! You just got a customer for life!Nelson S.Install batteries in radio and they worked as advertised good jobDavid S.These batteries came quickly and, best of all, they outperformed the rated capacity. I completely discharged each battery and then measured mAh for a full recharge. They exceeded my expecting. I will definitely buy these batteries again.Mark C.What can I say about a battery other that it arrived quickly, took a charge, and keeps my flag lit all night. It’s only been in use for a week so long term durability remains to be determined. Kris N.The 19650B battery is just what my LED flashlight needed for our application.Mark K.Batteries work great, take a charge and worked as expected.Vince H.HSo far so good.I bought these to replace another brand that wold not hold a charge.Thomas T.Bought these batteries from 18650 Battery Store for my new flashlight and they have lived up to my expectations. The 18650 Battery Store has a great selection and great prices as well.Jim G.I just recently started ordering from you guys. Mainly because of some of your battery specs I’m seeing. I ordered these 2 Panasonics because their specs are as high as some of the batteries I’ve been buying for 20-25 bucks. Yes there are just as good. I don’t know how long they’ll last but they Take a very good charge. Thanks guys for a great product. James L.Fast shipping. Pre charged.

Keep on producing and I’ll keep buying.

I have found my battery store.J.C.3 out of 4I bought 4 of these and 3 were as expected. A little higher than advertised capacity and charge-up just fine. The 4th has low voltage and takes for ever to recondition to full capacity which is a bit under what is advertised. I sent an exchange request email to the seller a couple days later and never heard back from them. I guess I’m stuck with 1 lousy cell and they (all over 1 marginal cell) don’t get a repeat customer. It’s a loose/loose and not how I like to play. Oh well!!Ben KProduct as spec’d, delivered as promisedTransaction was easy- good order follow-up. Product arrived as specified and on time.UnknownGreat TransactionGreat product and fast transaction.John MaganaFast Processing and shippingi ordered these at the beginning of the week and was hoping to get it before i had to ship a package overseas. i ended up getting the shipment wednesday afternoonTed Hansen18650 Battery PurchaseBatteries arrived in great shape and performance is right on!William SenskeMeets specs in charger but doesn’t last long in caDistilling run running tests but only lasted 4 days in my outdoor camera on the first try after it was chargedJeremy RymutBattery store delivers what I neededProduct came on time and product is excellent!!

Two of the batteries are showing good IR numbers, but the other two are slightly elevated, but for the, purpose I’m using the batteries for that shouldn’t be an issue.Kevin Ellisfast serviceFast service and a quality productKevin MurrayAs advertised- 3400mAHSolid battery, well packaged and arrived promptly.James Abbott18650 BatteriesTop notch quality.

Went from 3 hours runtime with a “12000 mah” battery to over 10 hours run time with a 3400 mah battery.john kirchnergood value for the moneythis battery charger was the least expensive of all of the ones I found, but it works well.
