Yuasa is a free Android application developed by PT. Santi Yoga that helps you maintain your vehicle's battery at peak performance. It offers a wide range of features such as automated battery reminders, an option to find the exact battery types based on your vehicle type (limited to Indonesian cars and motorcycles), and a list of trusted battery stores (limited to Indonesia). The app also provides a list of convenient stores where you can purchase Yuasa Battery products.

The user interface is straightforward and easy to navigate. The app's main page displays the battery status, whether it's healthy or needs attention. The app also shows the date of the last battery check, making it easy for users to keep track of their battery's maintenance schedule. The battery information section provides detailed information on the battery, including its type, voltage, and capacity. The app's store locator feature helps users find the nearest trusted battery stores that offer Yuasa products.
