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.

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.

The dimensions are not accurate. The actual dimensions are 71x22x22mm and do not fit a SMOK Mag Solo that will readily accept standard sized 21700 batteries. These are too large.

Bought 2 sets of these for a flashlight I use daily, very often during the day. Out of the four batteries one of them loses charge much faster than the other 3. Let it run a few charge, discharge cycles and then missed the return window, oh well. THe three of these that work, work GREAT and lost SUCH a long time in my flashlight. Thanks!

These are by far the best longest lasting flat top 21700A 5000 mAh rechargeable Li-ion batteries that I have found in the 7 years I’ve been vaping. Longest charge hold, for the money spent, don’t second guess these. I am not one to write reviews and these are deserving!

The pair I received do not reach a 100% capacity charge. They last about as long as my 2- or 3-year-old 18650s that I bought these to replace because, after being used that long on a continuous basis, it's normal for them to start losing charge, like 80% instead of 100%. Actually, one of the batteries charges only 30-40%, although both show 100% charged in the charger. Neither is. The one that charges only about 30-40% lasts only 3-4 hours. The other one lasts about 8 hours, if that. These are completely drained in less than a day. They do fit in a GeekSquad Max.New 21700s are supposed to last for a longer period before they need to be recharged, and these don't even last any longer than my OLD smaller capacity 18650s, so it appears that these were used by someone for quite some time before repackaged and sold as "new." These are listed as lithium-ion, but detailed information farther down describes them as "lithium-polymer."I'd forgotten that I'd already ordered a pair of 21700s from W*****t, thinking that I'd only looked at them. I discovered that fact before either pair had arrived. That pair DO reach a 100% charge, so I'm glad that I hadn't cancelled them. They last a whole lot longer than these you're reading about now. I highly recommend that you buy another brand from a different seller so that you won't be one of those disappoínted by your purchase, as I and many others were. Some were pleased, but the reviews make it appear to be a random chance that you will receive 100% new batteries.NOTE: These are 21700A batteries, which several reviews say are shorter and 1mm larger in circumference than normal 21700 batteries and won't fit in their devices, including certain flashlights and vape e-cigs. The ones I received fit, but don't even last 24 hours, so they drain much faster than they should and/or had been used for a lengthy period of time before reselling them as new.

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

These were the wrong size for my particular vape.I had to send them back.
