PRS-350 Sony PRS-350 Battery Issue

xpolarbearx · 02-26-2011, 08:51 PM

I have a Sony PRS-350 and I tried using an aftermarket charger to charge the reader. It showed as "usb connected" and "charging" on the screen but it actually drained the battery. After fully charging it via the mac usb port the battery doesn't seem to last long at all. It goes down to one bar while reading on and off in one day. Did I kill the battery or will it fix itself after a couple more complete charges? I did get a blackberry micro usb charger that allows charging while reading so I'm not sure if that is the problem also.

Firstly you need to leave it to charge over night... the charging light goes off at 80% charge, secondly do not put through full deep discharge cycling... these are Li Polymer batteries not NiCads, letting a Li Poly battery run all the way down is harmful (battery manufacturers information). Blackberry chargers are reported as fine and ideal to leave charging overnight... see numerous other threads relating to batteries for much more detailed information...
