I'm pretty sure that it would still need a 12v power source (like the one you listed), so any car battery should do the trick. The battery that you listed is only rated at 2.5 amp hours. A typical rating for a car battery, by comparison, is about 45 amp-hours, with some deep-cycle batteries being rated at or near 225 amp-hours. So the battery that you have listed will thusly last approxiamtely 1/18 of the time of a typical car battery to 1/90 of the time of a deep-cycle battery. Most radios pull 5-7 amps of continous draw. So you should get 30 minutes on your original battery.
