Put a voltmeter across the negative terminal and the actual positive wire and have someone crank the engine. Look at the voltage while cranking. It shouldn't to much lower than ten volts.
My 2006 had a weak battery but it would easily crank the engine over, but the crank time to start was long. Turned out to be the battery not supplying enough voltage to the fuel pump. I almost replaced the fuel pump.
