Diesel truck owners experience parasitic battery drain from aftermarket devices, leading to dead batteries overnight, with difficult diagnosis and costly consequences.

Workarounds Described

• uses multimeter to test circuits manually
• takes truck to mechanic for diagnosis
• guesses which device is causing drain

Implied Software Gaps

• Mobile app that automatically detects and identifies parasitic drain sources without manual multimeter testing

BatteryEye

BatteryEye is a smart battery monitor that plugs into the OBD-II port and detects parasitic drain in real-time, alerting the driver via smartphone before the battery dies. It identifies the offending circuit using current profiling, eliminating guesswork and reducing towing costs.
