Try to shock the battery back to life with hi and low alternating voltage. The best to use is an old school analog charger. Do it with a battery OUTSIDE of the car.

If you can't get it back to 13v consider replacement. The procedure may take a day or more.

If in a hurry you can take it to the retailer but their methods may be to just make you buy another....depends on how patient you are.
