A:
Battery life will vary, because the power consumption of electronics varies drastically depending on how you use them. Many manufacturers shy away from specifying it, instead they quote milli-Amp-hours (mAh) which is a measure of how much current it can produce and for how long. The genuine Sony battery pack has 1200mAh. This battery has slightly less - 1000mAh, so it is probably comparable to the performance of the original Sony battery when it was new.
