I just bought this battery off of amazon and after charging the 3rd led light flashes constantly and when putting the battery in the aircraft I get a high voltage error. This batter was made last june as it stats on the package. I discharged the battery twice to 0% and even slow charged the battery last night. Still same result. Is this battery toast or is it possible for the battery to fix itself.

Defective during manufacturing.  Will not fix itself so needs to be replaced.

I just bought the battery from Amazon so I will return through them and get an exchange. Thanks to all that have responded.
