The Joye 510 battery has a typical lifespan of about 200 charges, according to the manufacturer. Of course, real world experience tells us that this may not be the case. Some people have reported that the battery will last 4-6 weeks, while others say they last a lot longer. All electronic parts will eventually fail, so it is recommended that you have spare batteries so that you will not have any interruption in your daily vaping.
For the ultimate flexibility, have at least 3 batteries charged at all times. For the times when you are on the go, a Personal Charging Case, or PCC, will allow you to charge your batteries without an outlet.
Also, check your warranty on your parts. If your battery fails before the end of your warranty, contact your supplier for a replacement.
