You might have a bad alternator, in which case when the engine runs, it doesn't charge the battery like it supposed to. Next time you jumpstart your car, make sure you turn off all accessories (lights, radio, etc), and once your car starts, let it run for at least 2 or 3 mins so the battery charges up.
 
Sounds like the "new" battery is bad as well; it’s not that unusual if it’s been sitting on the shelf long (batteries not being rotated on store's shelf – older up front and newer behind - like milk in a grocery store). Take the battery back to the place you bought it and get it tested. Also, on the battery there should be a “creation” date of when it was made. If it’s more than six months the battery could have lost it’s charge sitting on the shelf.

Also, check the battery cables for corrosion (white flaking powder), especially under the red rubber cable end (positive cable). It can even be in the cable, it'll be swollen and deformed, when squeezed you'll hear a crunching sound. If you see corrosion take baking soda with a little bit a water using a small wire brush to brush away the corrosion. The baking soda neutralizes the battery acid (white flaking powder) you'll hear it sizzling. Let the caked on baking soda "stand" on the cables for between 5 - 10 minuets then wash it off with water very well. Also, do not to get it on your clothes or it will eat right through them. You might even need to either replace the cable or cable ends if very severe (unlikely with only 4-5 yr old vehicle).

If this does not fix it. Take it to a shop; it could be a number of items from a simple wire short, bad starter solenoid to a computer problem.
