Replacement battery for Sony PRS-350

This lithium-polymer cell replaces the original 1-853-016-11 pack in several Sony Reader models. It suits owners of a PRS-350, PRS-350SC, PRS-650, PRS-650BC or PRS-650RC who need a fresh power source. The unit is brand new and built to match the factory specifications.

Low heat and silent operation from a 3.7 V 900 mAh

The 3.33 Wh capacity delivers typical e-reader run time without measurable warmth or audible noise. Li-Polymer chemistry keeps self-discharge low during weeks of storage. Power draw stays modest, so the device charging circuit handles it without stress.

Slim black pack fits the original battery bay

At 62.50 x 52.65 x 3.50 mm the brick slides into the reader’s compartment with no modification. The black finish matches the internal aesthetics of the supported models. Buyers who need a different voltage, a higher capacity or a connector for another brand cannot use this item.

Questions about this item

How do I install the DS-CS-PRD350SL battery in my Sony PRS-350 or PRS-650, and what step is often missed?

Power off the reader, remove the rear cover, disconnect the old pack, connect the new 3.7 V 900 mAh cell, and reassemble; the step often missed is fully charging it before first use.

What maintenance will this 3.33 Wh Li-Polymer pack need over its life?

No routine maintenance is required; store at roughly half charge if unused for weeks, avoid deep discharge, and replace the pack once run-time drops noticeably.

What limit appears first during a long reading session with this replacement battery?

The 900 mAh capacity sets the runtime ceiling; continuous page turns and front-light use will drain the 3.7 V cell until it needs recharging.
