Query: Battery life not as good as I had expected

After only a few weeks, the batteries' ability to hold the charge decreased significantly. My Canon Powershot A540 would show full battery at first and then be completely drained after 3 hours of light use. Not good for trips, you're better off buying lithium batteries or regular batteries for cheap. I would not buy this product again.
