21700 Battery, 2PCS 5000mah 3.6V 21700 Flat top Battery 21700 Rechargeable li-ion Battery Green with Battery Organizer

Since homelife does not seem to be making batteries for vape devicesI needed to find a company that offers 21700 bateries as sparesso I decided to test these against the one home life 21700 batery I have batteries appeared to be close to fully charged when delivered so I put both bateries in my charger and let fully charge up.And now I am testing the first one in my lost vape Thelmalina so far it is holding a charge around 85 percent on the first battery when I put it in device it said 99 percent and then dropped down quickly to 85 percent but it seems to be holding the charge it could also be the vape device is trying to adjust also to the new battery also so I need more time to test it.As I bought these based off of others reviews which are good for vape devices.My homelife 21700 is rated for 4000mah.These say 5000. Mah not sure if they are actaully that but defenetely seem very close to the rating of my homelife battery.While update once more testing is done and I have had a chance to test both bateries over a week.I know I need to find suitable batteries since a lot of vape shop seeks to not want to carry vape bateries anymore and home life is no longer warrentieng them with insurance anymore.Next up 18650 bateries as I need to get a few more vape devices that take those ones but in a 2 batery format.Update while the both bateries quickly went from 100 percent on my vape device to 85 percent it held at 85 percent for over 12 hrs and I got almost 24 hrs of vape use from the first battery down to 17 percent right now the second battery is at 63 percent and it has been over 15hrs so so far these batteries seem to be meeting or exceeding the homelife 21700 batery rated at 4000mah and my tank has, stopped leaking vape juice since the switch.More I have not tested these batteries yet at 55 60 watts yet I am testing at 45 watts with a, fat rabbit tank and hellbeast coils.And again diferent vape devices can throw off readings on batteries also if note I am using a, slow charger to charge the batteries which takes about 15 hrs to charge these batteries which is a USB style 4 battery charger with an adapter plug to charge ac.Also I do not recommend using the vape device charger for charging unless it's short term or In an emergency.Will do final update in a few daysAnd my comment about vape device is to push back against the one reviewer who complained that he got an 87 percent reading after a, full charge and dropping down which again can be the device the key is does it match or exceed the old bateries charge and last longer between needing recharges.

I bought this item saying it was a 21700 battery, never paid any attention once receiving. When trying to install in my flashlight the battery would not fix, too large of a diameter, way past the return windowIf you look at the picture on the ad it does show 21700A, my errorNow I have 2 batteries to pitch that will not work

These batteries store a LOT of energy and last a long time. Super fast shipping. Would buy again.

These are to large for BSS Trunite flashlights. My oversight I suppose. However they look to be great batteries for what they are for.

Batteries charge quickly and last days. I purchased them for my Vaporesso Armour Max Pro and loved them so much I got another backup set. These cost twice as much at a vape shop so the value for the money is excellent. They fit better than the 18650 batteries which require a sleeve. Very happy.

I bought these Svenirven 21700 batteries for my vape device, and they’ve been working fine for the past three months. They hold a charge and get the job done, but there are a couple of things to note.The size is slightly larger than the standard 21700 batteries, which makes it a bit tricky to fit into my device. They do fit, but it takes some effort.Also, they seem to drain faster compared to higher-quality batteries I’ve used before. That said, they work well enough for daily use, and the included battery case is a nice bonus.Overall, I’m satisfied with the purchase for the price, but if you need longer-lasting batteries, you might want to look at premium options.

I ran these through 10 cycles to be sure, and the BEST of 4 cells was able to take 2300mah, less than half of what this item description claims. Quality 18650 cells have higher capacity than this inferior cell. The description is misleading and deceptive. There is no way this is an accident: I bought 4 cells and all of them are exactly the same. Look elsewhere for quality cells.

I was leery due to all the price variations of e-cig batteries. The vaping store was charging $35 each for comparable batteries. I was nervous but needed a 21700 for the e-cig. I don't remember the cost, but it was a significant savings and they are functioning perfect
