What do you mean by, "acting like it needs a jump?" Do you mean that it cranks slow or that all the lights go out on the dash when you try to start it? Have you had to jump it?
Even though the battery is only 2 years old there are many things that could wear it down prematurely.
You could have a drain on the battery or it's possible there is just a bad cell in the battery.
I would suggest that you take the vehicle to the place where you purchased the battery and have them check it. You may even have a warranty left on it which they will pro-rate for a new battery.
As for the "round house" on your instrument panel, I'm not sure what that is. I would suggest that you check your owner's manual to find out what this indicates.
