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.

Works great in my Sony headset

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.
