Why does the Haval Big Dog lose power after being parked for a few days?

[Leroy]

Reasons why the Haval Big Dog loses power after being parked for a few days: 1. The internal plates of the battery have fallen off, causing severe self-discharge. The battery cannot be left unused for long periods, so a new battery needs to be replaced in this case; 2. The vehicle's discharge current is too high when in a dormant state. The Haval Big Dog is a compact SUV under the Great Wall Motors brand. Taking the 2021 Haval Big Dog 2.0T DCT 2WD Chinese Hunting Dog Edition as an example, it features a 5-door, 5-seat structure with a fuel tank capacity of 61 liters. In terms of power, the 2021 Haval Big Dog 2.0T DCT 2WD Chinese Hunting Dog Edition is equipped with a 2.0L inline four-cylinder turbocharged engine, with an aluminum alloy structure, delivering a maximum power of 155 kW and a maximum torque of 325 Nm, paired with a 7-speed dual-clutch transmission.
