I think every camera comes with a battery.
You can go for Sony DSC H9, nice optical zoom with reasonable picture quality.
Retail : 22k
Other Way: 18k
But if aren't for brands then go for Canon 12X optical zoom or Olympus 18X optical zoom camera.
I am all talking about optical zoom cams because when u will use them u will definitely love them because the subject and situation is never always near you to get clicked.
You would love to take picture of birds..hehe...yeah..birds...anywhere...everywhere.
