TOPUSSE 3.7V Rechargeable Battery, 30A 2500mAh Rechargeable Lithium.ion Flat Top Battery for Flashlight. (4 Packs)

Great Batteries (so far) at a great price!! But only time will tell. I will update review, if they turn out to be not so great. But I don't think that'll be the case. Charge speed is basically the same as other 18650 batteries that I have, which charge just fine. Can't be more specific as I don't "time" them as they ccharge. Their size are perfect. Can't speak on life span of the batteries, but they stay charged and keep my devices working better than some other 18650's I have. Would definitely recommend

Good quality batteries. I've been using them for a while by replacing the old batteries from my Impact hammer drill. They work great.

Great replacement for vape batteries.

All 4 batteries capacity tested right around 2600 mah +/-, weight 45-48 gm.

For anyone that has a e cig mod/Vape, these do work can confirm. Went to 3 smoke shops to find batteries and they didn't carry them due to ban. Works great on geekvape aegis legend 2. 18650 battery 👍

I give these a good rating. CAP Tested and they are within the stated SPECS!

Compatibility to my vape devices. Good capacity. Stays charged for sometime. Comes with case for them.

This is the third battery set I have purchased on Amazon and the only one that comes anywhere close to meeting its advertised specs. From my observations, many other batteries that advertise 3400 mAh capacity test at around 1800 mAh and weigh a few grams less than these. Which is do you want, a 2500 mAh battery or an 1800 mAh battery with a 3400 mAh label and some deceptive advertising? My recommendation is to read the reviews. Ignore the ones that say the battery worked and look for reviews where the capacity was actually measured.
