Query: Not OEM, did not charge properly

Purchased this because it said "Toshiba" and not "replacement," thinking I was getting genuine Toshiba part. This is misleading, since it is the exact same battery as the one sold on Amazon for half the price, listed as a replacement. They are both generic substitutes for the Toshiba battery. To make matters worse, this battery did not charge up properly, or hold the charge.
