Applicable Products and Categories of This Article

The battery for this model of Network Walkman™ player (see the Products section below) can be charged from empty to full approximately 500 times. However, the actual number of charges possible in the lifetime of the battery will vary depending on the condition of the player and of the battery.

NOTE:  Charging the battery from a completely discharged state to a full charge is considered one charge for the Network Walkman battery. However, charging a battery that is not completely discharged does not reduce the capacity of the battery.
