Questions about this item

When will the 1.4 Ah Li-ion battery need replacing?

The 1400 mAh cell is rated for several hundred full charge cycles before its run-time drops noticeably; typical e-reader use reaches that point after two to three years.

What stops the DS-CS-PRD900SL from running longer on a single charge?

The 5.18 Wh capacity is the hard limit; once the 3.7 V cell discharges to its cut-off voltage the reader shuts down regardless of load.

Does the 59.74 x 46.51 x 6.61 mm pack get warm or noisy during all-day reading?

Li-ion chemistry in this size produces no audible noise and only slight warmth during normal discharge; no fan or active cooling is present.
