18650 Rechargeable Battery 3500mAh 3.7Volt Flat Top 2 Pack Large Capacity 18650 Batteries for Headlamp Led Flashlight

Giving these 5 stars after a week or so of using them. I am using them in a box mod, running at around 60w on a dual coil RDA. If you know, you know. They last just about a day (I put them in the charger at night, run a different pair of similar rated for the night and swap these in in the morningish time). I will update if they die early but they seem to charge at 1 amp pretty quickly, they're usually around 3.50v when I put them in, couple hours later they're at 4.2v. Happy so far.

These are really good batteries.. fast shipping holds amazing charge

Last about 8 to 10 hours on a charge. Good for the price

These work great. No problems charging or longevity.

Bought 3 months ago. Both will no longer charge. Not talking about holding a charge - these will absolutely not charge. Deadsville. I do not recommend purchasing these batteries.

very very good!

2496 mAH when charged to 4.2V then discharged to 3.4V by 1A current.I gave 4 stars despite of wrong labeling and advertising because all Li-Ion cells I bought from Amazon are being advertised to have 2-3 times more capacity than they actually have.Otherwise, good cells, 22 and 26 mOhm internal resistance. Good pair, have the same capacity that is not common when I used to buy other brands from Amazon.Edit: bought for the second time. Disappointed. Now they have capacity around 2000 and resistance 41 and 43 mOhm. Lowered to 3 stars, average accumulators.

Perfect fi for my high dollar flashlight.
