Camcorder batteries questions

[Netty]

Hi
We have a sonydcr-hc22e mini dv camcorder. I need to buy a battery for it as we only have the one that came with it. The battery we have is infolithium p series.
Can anyone recommend a website to buy one from and also how many minutes do they last for?? I know that using the lcd screen shortens the time.
has anyone used this site? Their batteries are very cheap.

i got mine from Amazon but can't remember how much it was. may be worth a look, if only to compare prices.
