Lenovo ThinkPad Edge E525 - Manual (Page 54)

The battery status indicator will let you know that the battery is charging, and will also notify you when the
battery is fully charged.
Note: To increase the life of the battery, the computer does not start recharging the battery if the remaining
power is greater than 95%.
Maximizing battery life
To maximize the life of the battery, do the following:
• Use the battery until the charge is completely depleted; that is, use the battery until the battery status
indicator starts blinking orange.
• Recharge the battery completely before using it. The battery is fully charged if the battery indicator shows
green when the ac power adapter is plugged in.
• Always use power management features such as power modes, screen blank, sleep, and hibernation.
