Sony 2 hr. Lithium Ion Camcorder Battery

I have used this battery for a couple of years with no problems in my Sony camcorder.I bought it to supplement the smaller battery that came with the camcorder. It has lasted up to two hours of recording time.I don't usually recharge it after short usage time, but when it shows on my camcorder screen that it is getting below half charged, then I make sure to charge it up so that it is always ready when I need it.This has always given me an accurate reading on my camera of the time left on the battery, so I don't get any surprises.Depending on how low the battery is, it sometimes takes me up to an hour to charge the battery.I am happy with the amount of life I have gotten out of this battery and it is still going strong.
