Notes on Using the Battery
About the battery pack
The supplied battery pack is designed specifically for your tablet device.
For your safety, use only the supplied battery pack or an optional battery pack specified by Sony.
Depending on the ambient temperature or how to use your tablet device, the battery may not be charged, or it
may take a long time to charge the battery.
Do not charge the battery near fire or in direct sunlight.
While your tablet device is plugged in and has a battery pack installed, it runs on AC power.
The supplied battery pack is not fully charged when shipped.
Heat builds up in the battery while it is in use or being charged. This is normal and is not cause of concern. If
your tablet device or the AC adapter becomes abnormally hot, shut down your tablet device and unplug the
AC power cord (mains lead) from the AC adapter.
Do not use your tablet device without the battery pack inserted.
About battery discharge
After charging, the battery gradually loses its charge even if it is not used. If it is left unused for a long time,
the battery charge may be depleted. We recommend recharging the battery before use.
If you do not use your tablet device for an extended period of time, fully charge the battery every six months.
About battery life
Battery life varies depending on usage, settings, and temperatures.
About battery deterioration and replacement
The capacity of the battery pack gradually declines through repeated recharging and discharging. As a result,
the battery life may become short or the battery pack may not perform optimally even when fully charged. If
the battery life has become short, replace it with a new battery pack specified by Sony.
If the battery pack quickly runs out of power after being fully charged or will no longer accept a charge,
replace it with a new one.
