Need a little advice on my battery

Hi guys my son wants to try out ice fishing so I am trying to not spend a lot of money before I know if he likes it or not. I have a Lowrance Elite 7 hdi that I have seen guys use as a ice fishing flasher, I plan on using it for a while to see if my son likes ice fishing enough to buy a flasher. My issue is I have a 12 volt 7ah battery that I charged it and it doesn’t seem to have the power to keep the elite 7 running. It is a battery that is probably 3 or 4 years old and it hasn’t been used in a year or two, is it possible that the battery is bad. How big of a battery should I go get to get this running as this is the only thing that is stopping me from this working. Any help will be great as he seems excited to go out ice fishing. Thanks Jusitn

Ya new battery time, that battery is less then $20 and should run that graph for 7 hours no problem.
