Authentic 30QP Rechargeable 3.7V 18650 Battery Flat Top, Real 3000mAh(2PCS, with Free Plastic Case)

Samsung batteries.Two batteries in plastic case.They work great in my laser.Fast delivery too! No negatives!

My daughter says these are very long lasting vape batteries. Her favorite brand. They also stay in the mod, and do not cause the mod screw cap at the bottom, to pop off. Which means the length is perfect. That helps if you have a faulty bottom screw cap to battery chamber. Last all day.

Excellent

So I was curious, but couldnt find anything on the inter-webs.. are these really authentic? I feel like they’re fake and just marketed as real….but who knows. They work fine….

Good but not great

CAN BE RECHARGED , THIS DOES THREE THING I DONT TO BUY A REPLACEMENT, JUST RECHARGE AGAIN AND AGAIN, THESE RECHARGES SAVE ( IN THE LONG RUN) MONEYDO THE NUMBERS, REPLACING THIS WITH NON RECHARABLE WHICH COME IN LARGE PACKAGE AS YOU USE THESE UP TAKE TIME AND SPACE AND YES RECHARABLES ARE MORE COST BUT EVERY TIME YOU RECHARGED YOU LOWER THE COST TO A LEVEL THAT IS A COST SAVINGS AND YOU ALWAYS HAVE A BATTERY THAT JUST NEEDS RECHARGERING NOT REPLACING EVERY TIME. POWER OUTAGES NOW CAN BE HANDLED WITH USING 20V BATTERIES TO RECHARGE YOU SMALLER BATTERIES OR YOUR PHONE IN A POWER OUTAGES, WHICH MIGHT COME IN HANDY IN BAD TIMES

Definitely doesn't seem like listed capacity since batteries from other source last much longer with same or similar specs. Hard to prove not gonna bother to ask for return but won't buy again from this source.

I took my flashlight apart and changed this battery, it works like new
