Replacement battery for Sony PRS-500

This lithium-ion pack replaces the original battery in Sony Portable Reader PRS-500, PRS-505, PRS-505/SC and PRS-505SC/JP models. It matches the OEM part numbers 8704A41918, 1-756-769-11 and LIS1382(J) so the e-reader recognises it immediately. The cell is supplied new and ready to install.

Thermals noise and power draw in normal use

The 3.7 V chemistry runs cool during typical reading sessions and adds no audible noise to the device. Built-in protection circuits guard against over-charge, over-discharge, over-voltage and short-circuit conditions, keeping power delivery stable and the battery safe throughout its service life.

Capacity decides if this is the right part

Rated at 700 mAh (2.52 Wh) with a verified 680 mAh typical capacity, the pack fits the 52.0 x 34.0 x 4.0 mm compartment and weighs 38.2 g. Buyers whose reader requires a higher capacity or a different voltage should look elsewhere.

Questions about this item

How do I install the Estry 700 mAh 3.7 V battery in my PRS-500 or PRS-505 reader?

Power off the device, remove the rear cover, disconnect the old pack and connect the new one matching the 3.7 V polarity; the 52.0 × 34.0 × 4.0 mm dimensions ensure it seats flush without forcing the housing.

What maintenance or replacement will this lithium pack need over time?

The cell is sealed and maintenance-free; when run-time drops noticeably — typically after several hundred full charge cycles — replace the pack with another 3.7 V 680–700 mAh unit such as part 8704A41918 or 1-756-769-11.

What limit appears first during sustained reading sessions with this battery?

The 2.52 Wh capacity sets the practical ceiling; continuous page turns and backlight use will drain the 700 mAh cell in a single long session, requiring a recharge before further use.
