The Extended Life and Overnight battery can take up to 10-12 hours to fully charge.   The battery icon on the display will stop flashing when the battery is fully charged.  Please note that even if the battery icon is showing 4 bars, this indicates that it is only at 75%. When the battery icon stops flashing, the battery is 100% charged.

Always store the battery separately from the PowerShell and if you are not using your battery on a continuous basis, please fully charge every 2-3 weeks, then remove from PowerShell.
