100% Authentic Samsung25R 3.7V Rechargeable 18650 Battery 25R Flat Top, Real 2500mAh(4 Pack, with Free Plastic Case)

Although I'm not using these for any vape devices (havent vaped in years), but rather they are for use in my replica Star Wars Lightsabers (specifically in the hilt to power to board that runs them). But from my vaping days, which go back nearly a decade when we built our own coils, there were no "mods" i.e. vapes with battery overdraw built in to prevent explosions in your face because the battery wraps are 95% of the time inaccurate, which causes problems when you build coils to a specific ohms level for best performance and SAFETY, the days when vapes were a metal tube that would have an atomizer screwed into them on top, a literal pipe bomb almost.. so we HAD to get familiar with batteries, and the counterfeits as well.With all that said, I can confidently say that these are GENUINE SAMSUNGS. Tested 2 of 4 and got 2400 mah and 2350 mah. And they DEFINITELY put out the listed 20 amps they're rated for, as they have my lightsabers BRIGHT, and with these sabers 10 amps is the minimum required to power the 200+ leds in the blade, along with the other components. But 15 amp or 20 amp batteries work much better/are much brighter and overall better looking. And my sabers have NEVER looked better than they do when I pop a freshly charged one of these into them. Just wonderful batteries. Don't hesitate or contemplate other batteries, just do yourself a favor and get these. The price is fantastic as well. I may order 2 more packs of 4 just in case, knowing they're legit Samsungs.I'll add in, back in those vape days, when the MXJO 35 amp 18650 3600mah batteries came out, those were ALL we used. They were $20 EACH, and had QR codes ON the battery wrap to scan, to verify they were legit. When those came out, the Samsungs were demoted to backups, but fortunately I'm not talking about using them for vapes lol. The MXJO's would be major overkill for my sabers, and these Samsungs are just the best. Grab them while you can, never know when the listing will dissappear or something like that. I'd give a 10/5 rating if I could.

Was just getting into replacing Li-Ion battery packs instead of just throwing the battery-powered device away, but when I discovered almost every battery-powered drill, portable vacuum, leaf blower, string trimmer, and half my power tools use the same battery cells, just assembled in different combinations to provide the amperage and voltage required.I separately ordered a battery-powered spot welder making it easy to attach the nickel ribbon wire these battery packs use to interconnect the individual battery cells, so when I started doing these replacements I found these batteries were both the same dimensions, voltage, and amperage as used in all these battery-powered devices, and I found this specific brand provided the best quality and battery life.Don’t just by a few, you will need a dozen or more to get started!

These batteries worked great for my snap on wratchet. The batteries in the snap on were 20r and these were 25r. I did a little research and it didn't seem to matter. I do recommend testing the voltage. The snap on battery pack has 2 + and - sides. Make sure the voltage is even. If it isn't. Connect the positive and negatives together for 5 mins or so. This is because the snap on charge is anal about it. Once you do this the battery works perfect.

These batteries work just fine for vape devices. Every 18650 battery I've bought for vape mods/devices have included the "NOT FOR E-CIGARETTE DEVICES" and I've never had an issue with any of them. I would be fairly certain batteries bought on a vape site or store would carry the same warning. The reason I'm unsure is that I've never paid $16-$20 for 1 battery at a vape store.

These batteries are Not of cheap quality.They deliver reliable performance you can count on.I use them in flashlights as a replacement for the non rechargeable 3AAA setups

If you’re gonna buy replacement batteries for your vape, these are the ones that you buy. They last longer than anyone that I’ve ever bought before.

These charge slowly, run down quickly, run out unevenly... Just... Garbage. Don't buy these. Spend the extra and get something real.

I believe these are the real deal, this is my second purchase of Samsung 18650 batteries. I am very loyal to company that sells a quality product.Thank you 👍👍
