Very good quality battery. It has performed equal to original battery. Cost and product quality were drivers for making this purchase with Battery Mart. I highly recommend using this vendor for future purchases.

This battery works great in my Sony headset. The length of the charge is not determined yet since I haven’t done a marathon of TV watching since I got the batteries. Hopefully it will last 4+ hours.
