100% Authentic Samsung30Q 3.7V Rechargeable 18650 Battery 30Q Flat Top, Real 3000mAh(2 Pack, with Free Plastic Case)

These genuine batteries have served me well for over a year. They charge quickly and last a long time. I like them.

Very happy with these batteries, my old ones would get super weak at 60% life and these not only have way more power but stay the same all the way down to 10% I didn't even notice they where low. So I just ordered a 2nd set of them. Great batteries for mods and flashlights.

I just got these in the mail an they have warnings all over them saying not for vape an could cause a fire I'm confused cause I got these for my vape mod, do these need to be returned cause they aren't for what I needed them for?

I very seldom purchase through a non- Prime seller but even though I paid nominal shipping I’m happy with the product

They will take around 2900mha just like real Q30 batteries do discharge rate of 15 amps everything is in specification

Charged these up and they have good battery life. Happy with purchase.

I am not sure what happened but these were the exact batteries that came out of our light. These immediately overheated and I put them outside because it seemed they just got hotter and hotter. I did return them without hassle.I don't know what the issue was, but there certainly was one.Very happy with the return process, very unhappy with this battery experience.

These "Samsung" 2500 mah batteries perform poorly in my devices. My charger and test instruments show them barely able to reach 4.2 volts new and hold less than 2000 mah,(advertised as 2500 mah).They came in a generic plastic wrap with jet-printed labeling.
