I ordered the battery, because my Acer reported 5742 g, the battery is defective and should be replaced. The order was delivered quickly. Packed the battery is securely in a cardboard box. The battery fits just as good as the original but convinces with a better life than the aged original battery.
The battery impresses in every aspect and I recommend this battery to anyone who needs a new battery and want to spend a fortune for a no original battery.
