Yes.
If you need to jump start the car then the battery may be fully charged but it is defective and needs replacing. A full charged battery will read 12.6 volts at the posts with the engine not running. 12 volts indicates the battery is only 25% charged.
As long as the battery is fully charged it will start no matter the condition of the alternator. Eventually the battery will run down if the alternator is not keeping it charged.

The 2007 Chevy Cobalt features two batteries primarily for its audio system and additional electronic components. The second battery, known as the "auxiliary" battery, helps to provide extra power for features like the sound system, which may draw more current than the primary battery can supply alone. This setup ensures that the vehicle's main battery remains charged and can reliably start the engine while supporting the electrical demands of the car's accessories.

Low/bad battery, bad battery connection. If the battery isn't getting fully charged you might not be able to start. If it isn't getting charged, check the alternator.
To charge the battery on a 2006 Honda CR-V, first ensure the vehicle is turned off and park it in a safe location. Connect the positive (red) jumper cable to the positive terminal of the dead battery, then attach the other end to the positive terminal of a charged battery or a jumper pack. Next, connect the negative (black) cable to the negative terminal of the charged battery and attach the other end to a metal ground on the CR-V, away from the battery. Once connected, start the vehicle with the charged battery, let it run for a few minutes, and then try to start your CR-V.
It will start if there is enough charge in the battery to turn the engine over. However if the alternator is weak then the battery will not be charged fully.
