I purchased a cell phone battery. When I put it in it said 80% charged, so I charged it overnight. It showed full charge the next morning but by evening it was dead and my phone shut off. I know sometimes you have do several charge cycles to bring a battery up to its full potential so I gave it two weeks. It still does not last a whole day, and I don't make many phone calls. The two year old battery I took out of my phone lasts longer than the new one. I took it back to the store and they said I guess I should just charge it every night.

great brands @ great prices. They bought my used battery for $5.
