  • Product typeEbook Battery
  • Compatible with Sony PRS-300 series readers

Replacement Battery for Sony PRS-300 Series

This lithium-polymer cell replaces the original 1-756-769-31 pack used in Sony PRS-300, PRS-300BC, PRS-300RC and PRS-300SC e-readers. It delivers 3.7 volts and 680 milliampere-hours in a slim 52.00 by 34.00 by 4.00 millimetre black casing. The unit is brand new and built to match OEM fit and electrical specification.

Suitable for Owners of Listed Sony Readers

Readers who need a fresh power source for a PRS-300 family device will find this a direct swap. Buyers with other e-reader models or those requiring a higher capacity than 2.52 watt-hours should look at alternative options.

Capacity and Runtime Expectations

The 680 milliampere-hour rating restores the original runtime for typical reading sessions on the supported devices. Heavy use with frequent page turns or wireless features active will drain the cell faster, and the fixed 2.52 watt-hour capacity cannot be extended without a larger battery.
