new camera-a big disappointment

I'm very disappointed with my new trail camera. 10 megapixels should look better than this. I do have it set on the highest resolution. The battery still shows to be charged, but it refused to take pictures after 263 & the last few were very dark. It has a 6v rechargeable battery & I have tried using it for several days. I have to recharge it every day & I have still never made it through the night.
