I bought an Aspire CF VV 1600mAh battery September 30, 2014. Initially the battery worked fine. It now only works correctly intermittently. Sometimes it blinks amber, sometimes it blinks blue. In either case there is no output. The battery is fully charged when this occurs. I tried to return it for an exchange at the retailer I purchased it from, but they refused.
I have a second Aspire CF VV 1600mAh battery that works just fine, so I tend to believe the battery itself is faulted. Since all my set-ups work just fine with a number of batteries, including the additional Aspire battery, I do not believe they are in any way at fault.
