Your Vuse ePod 2+ should last for about 300 full charge/discharge cycles before battery efficiency begins to deteriorate. This is common with all lithium-ion batteries but will depend on your personal vaping behaviour.

After this period, you can still use your Vuse ePod 2+ device, but you may need to charge it more frequently. Keep your Vuse ePod 2+ battery charged to maintain the battery life.
