My car battery died wihtout a warning so I called a friend for help. He jump started my car and recommended I have the battery checked out at Auto Zone. I was there in a few minutes and my battery tested after another few minutes. Yep, it was bad. I called Toyota and founf out my bateery still had a 50% warranty on it. The kind lady at Auto Zone advised me to get a new battery from Toyota to save me some money. Great experience.
