What are the reasons for the dead battery in Haval H6?
2 Answers
Haval H6 battery may be dead due to the following reasons: 1. Short driving distance; 2. Frequent ignition; 3. Electronic circuit issues; 4. Engine not charging; 5. Battery failure; 6. Prolonged use of high-power electrical appliances; 7. Unclosed electrical appliances after locking the vehicle; 8. Short circuit or open circuit between battery poles or loose connection of battery terminal clamps. Taking the 2021 Haval H6 as an example, its body dimensions are: length 4615mm, width 1860mm, height 1720mm, with a wheelbase of 2680mm. The 2021 Haval H6 is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 150PS, a maximum torque of 210Nm, and a maximum power of 110kW, paired with a 6-speed manual transmission.
My H6 had a dead battery last time, and I learned a few lessons. Leaving the headlights on is the most common mistake, especially when parking in underground garages. Daily short commutes are another pitfall—just ten minutes to and from work isn’t enough for the alternator to fully charge the battery. Winter makes it worse; at minus ten degrees Celsius, the battery won’t even start the car. Last time, I installed a dashcam but wired it wrong, draining the battery overnight. I recommend checking the battery’s inspection window regularly—green means it’s healthy. Keeping a portable jump starter in the car is crucial for midnight breakdowns. Also, get the dark current tested at a repair shop; fix any abnormal power drain early, or a new battery won’t last long either.
