Part 3. Exercise
I recently received a refurbished View as a birthday gift, charged it up, set it down a couple of days. When I picked it up I found it was dead. I charged it again, called Sansa about the issue and they agreed it was a bad battery after diagnosing the problem. They also told me the battery is not replaceable and after warranty you throw these units away. Now I need to deal with Buy.com to see if they will give me my money back or replace the unit hopefully with a e200 series. The e200 series has inexpensive replaceable batteries.
Answer:
Negative
