after charging, test the battery with a hydrometer. A fully charged battery shows a reading of 1.265 or higher. Repeat the charging process if readings are low.

9. Reinstall the battery

once reconditioned, reinstall the battery in your car. Connect the positive terminal first. Then, connect the negative terminal. Ensure all connections are secure.
