Even the best battery can fail if you charge it wrong. Here's what to do:

• Use the included cable and adapter. Third-party chargers can push too much current.
• Don't charge overnight while you sleep. Set a timer or charge during the day.
• Keep the device away from flammable surfaces while charging.
• If the device gets hot while charging, unplug it immediately.

Most modern vapes have overcharge protection, but that doesn't mean you should leave them plugged in for hours. Heat is the enemy of lithium batteries.
