WiFi Battery Charger is a utility application designed for Android devices that enables users to remotely monitor and manage 12V battery charging. The software features a built-in stable Wi-Fi connection system, allowing for real-time tracking of battery charging current, voltage, remaining time, charging mode, and any abnormalities during the charging process.

Key functionalities include support for multi-battery monitoring and the ability to visualize the charging process through an eight-segment display. Users can remotely set various battery types, such as car lead-acid and AGM batteries, and adjust the charging current to options like 2A, 4A, 6A, or 8A. Additionally, the application provides alarm notifications for abnormal charging conditions and automatically generates charging history reports for performance evaluation.
