Why does the Haval H6 battery drain after a few days of non-use?
2 Answers
There is a leakage phenomenon in the vehicle's electrical equipment. Solutions: Manual push-start; Jump-start with jumper cables, which is time-saving, labor-saving, and cost-effective if another vehicle is available nearby; Towing by another vehicle if jump-starting fails and a vehicle is nearby; Using a portable emergency power bank to charge and start the vehicle. Battery: Batteries can be divided into traditional lead-acid batteries and maintenance-free batteries. Since the battery uses lead-calcium alloy for the grid frame, the amount of water decomposition during charging is less, and the evaporation of water is also low. Additionally, the sealed structure of the casing releases very little sulfuric acid gas. Therefore, compared to traditional batteries, it has advantages such as not requiring any liquid addition, easy connection to terminal posts, and long power storage time.
I encountered a situation with my Haval H6 where the battery died after the car was parked for a few days. This could be due to the battery aging itself, combined with hidden currents in the car secretly draining power, such as the anti-theft system or navigation not being completely turned off, causing continuous discharge when the car is stationary. Environmental factors are also crucial—battery performance declines faster in cold weather. I recommend not letting it sit idle for too long; start the engine and drive around weekly to recharge, or simply buy an automatic charger to plug in, avoiding being stranded next time you need to use the car. Additionally, check if the battery terminals are loose, as dust buildup can also lead to poor contact. Keeping the engine bay clean helps extend its lifespan.
