The online manual for this Canon SX 610 HS says, the battery should be good for 270-400 pics.
There is definitely something wrong, as the pic above does not fit in quality to a modern 20Mpx camera (which the Canon is).
This Canon would be a perfect hiking companion, its small, lightweight and has a 18x zoom, which would be great for an occassional wildlife shot.
The battery is replaceable and is to be charged in an external charger.
But its not waterproof, so you would have to take extra care for it.
For many years I carried a decent camera (Lumix with 18x zoom) on my hikes, but nowadays I just use the smartphone. Makes really great pics, is waterproof, and in my pocket all the time - the best camera is the one you have handy.
Only downside is that it has no optical zoom, so in a way we are back to the 80ties when all you had was a Kodak Instamatic and you had to impress your buddies back home by storytelling more than by pics.
