Any battery fully charged should show 12+ volts, almost 13 volts. After a full charge, it should not be 10 volts, the battery is dead. You can check the fluid level if the fluids are below the plates it's bad.

Check the owner's manual for the correct size and amperage of the battery. The car is used so it may not have the correct battery. Also, check the manual and see if there is an auxiliary battery for electronics. Brand new cars have them.

Once the battery is replaced or checked out to be good. Have your mechanic check out the charging system. It may or may not be charging properly. I've seen bad charging that does not trip a CEL.

Good luck!
