Will parking air conditioning cause damage to vehicle batteries?

Whether the parking air conditioning will cause damage to the vehicle battery mainly depends on the usage.
When using parking air conditioning, especially when the engine is not running, if the battery is low, it is easy to cause excessive discharge, which can shorten the battery's service life in the long run. In addition, parking air conditioning usually requires a large amount of power to operate, and if the battery capacity is small or has aged, there may be a loss of power.
However, if the parking air conditioning is used for a short period of time and the vehicle's battery is in good condition, the impact on the battery should be limited. When using parking air conditioning, some measures can be taken to reduce damage to the battery, such as minimizing usage time, avoiding use when the engine is not running, and regularly checking the battery status and level.
If the vehicle's battery condition is poor or low, consider using other power sources or backup batteries to power the parking air conditioning to avoid damage to the vehicle's battery.
In short, proper use of parking air conditioning can reduce damage to vehicle batteries, while also extending the service life of parking air conditioning and maintaining its good operating condition.
