Replacement for Sony e-readers

The Estry PRS-350 is a lithium replacement cell built to the original 3.7V 900mAh specification. It fits the PRS-350, PRS-350SC, PRS-650, PRS-650BC and PRS-650RC models and matches part numbers LIS1459MC9SY6 and 1-853-016-11. The pack is sold as a single unit and is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Capacity and headroom

At 900mAh and 3.33Wh the cell provides the same energy budget as the factory battery, delivering a full day of reading under normal use. Heavy page-turning, front-light use or frequent wireless sync will drain the charge faster, so a recharge is needed before the next long session. The protection circuit stops over-charge, over-discharge, over-voltage and short-circuit events to preserve cycle life.

Thermals noise and power

The slim 62.5 x 52.65 x 3.5mm, 43.8g pack has no moving parts and runs silently. In normal e-reader operation the discharge current is low, so the cell stays close to ambient temperature and adds no perceptible heat to the device. Self-discharge is minimal when the reader is asleep, leaving the stored 3.33Wh ready for the next use.

Questions about this item

Will this 900mAh 3.7V battery fit my older PRS-350 e-reader?

Yes, it is compatible with PRS-350, PRS-650, PRS-350SC, PRS-650BC and PRS-650RC models and replaces part numbers LIS1459MC9SY6 and 1-853-016-11.

How can I verify the 3.33Wh cell is working correctly after installation?

The device should power on normally and show expected battery-life readings; built-in overcharge, over-discharge, over-voltage and short-circuit protection operates automatically.

What comes in the 1-pack box and is any extra hardware needed?

One lithium battery measuring 62.5 x 52.65 x 3.5mm and weighing 43.8g is included; no additional components are required for installation.
