Notes on storing lithium-ion rechargeable batteries
A lithium-ion rechargeable battery is built into your Walkman. When you store it for a
long period of time, be sure to follow the storage instructions below.
Leaving a charged battery unused for a long period of time causes deterioration of
the battery and results in a decrease of battery capacity. The deterioration is more
severe when the battery is stored with a full charge, and is accelerated by
prolonged exposure to heat such as when leaving your Walkman in a car while
connected to the power port. Store the Walkman at temperatures below 35 °C (95
ºF). Charging or discharging the battery to approximately 50 % of capacity before
storing is also recommended.
The battery deteriorates when left in a depleted condition. Charge the battery to
approximately 50 % of capacity at least once every six to twelve months to prevent
deterioration.
