Samsung 25R 18650 Battery

These worked great in my vape. Had to turn them around so they wouldn't say they were dead after that gold

It had been 2 years since I bought new batteries. I bought 2 to cycle in and theyast for 2 days now (heavy vaper). Great product

Only have to change every 8-12 months, perfectly working through and through.

The batteries work just as advertised, came slightly charged which was unexpected. Side note, be careful to not click the fire button while putting in batteries
