21700 Battery Case Set 5000 mAh for Flashlight - 2 Pack

I was skeptical about buying these batteries. But got a good deal on the black Friday deal. I use 21700 batteries in my flashlight at work and use them very often. So far they seem to last as long as my original one does. I've bought cheap batteries in the past and they seemed lighter than the original one. But these seem weigh the same as the original one. At this point I am very pleased with the purchase!!

Holds a charge just fine. My vape will last about a day and a half now. Fits my regular sized charger. Worth the price. Would gladly purchase again.

Direct replacement for bad battery in my 10ah Dewalt 20V battery pack. The battery pack will now accept a charge. It did take a little Dremel work to make it fit.

these batteries have 10% of the advertised capacity. cannot recommend in good conscience. you can see in the pictures that they have roughly 500mAh capacity, when the ad is for 5000. troubleshooting information useless.

ok

This was a great deal for what is proving to be a great pair of batteries. I bought these to replace the batteries for my vape mod. After a full charge, I’m finding that they will last me all day before needing a recharge. It beats having to carry a charge cable with me everywhere. I’ll be returning for more when it’s time to replace these.

These charge fine, they've kept a good charge for me. Only had them a couple weeks but I go through a battery a day (heavy vaping, getting off of cigars after 40 years) so one gets charged every day while I'm using the other one and so far I haven't noticed any deprecation of capacity.

I love the 21700 battery set I purchased. The charge last a long time compared to other brands that I have purchased in the past. It was a great value for the price. The battery case is great for traveling as well. Would definitely purchase again.
