Ask an assistant to set the parking brake, put the transmission in (automatic) or Neutral (manual), and crank the engine for a few seconds, just enough to get a good voltage reading but less than 30 seconds.

Some parasitic drain is normal – your battery delivers enough energy to keep things, like your clock, radio presets, and security alarm operational at all times.

What to do when your car battery drains?
Start with a fully charged battery. If yours is low, use a battery charger, or have a friend assist with jumper cables from a good battery. Recreate the same configuration as when the battery drains overnight. Meaning, shut everything off, lock the doors, and take a key with proximity sensor away from the vehicle.
