When the battery light turns on in Your 2010 Toyota Corolla it could mean that there are a couple of potential problems. The first thing that You should check when Your light is on is the actual battery resting voltage. The light can give You a warning about Your battery being lower than it should be while the vehicle was off and that is a sign that Your battery is failing and will need to be replaced. If You don't replace it You may reach a point where the car will not start. The other reason a battery light may go on is when there is a problem with Your alternator. The alternator charges Your battery and if it is not charging at the correct voltage Your car will let You know.
