Rechargeable 18650 batteries
With so many choices and specifications, battery shopping can be overwhelming. The simplest method is to look for something with a higher mAh number if you want a longer lasting cell, and a higher amp rating if you want a stronger cell. If you mostly vape at higher temps, focus on the amps, or power. If you vape at lower temps and want longer battery life, get a battery with a higher mAh rating. Finally, if you use a box mod with more than one battery, it’s best to buy batteries in sets that you keep together and charge together, treating them as one.
The Samsung 25R is a high-quality 18650 battery that has earned a stellar reputation in the vaporizing community. The Samsung 25R was designed to be a good all-around battery with enough power to satisfy at higher temperatures. It is rated at 2,500mAh with a 20 amp continuous discharge rate. When you’re not sure which battery to get, this is a solid, safe choice.
