Temporarily put the lead-acid battery upside down for a few minutes and then recovered it before starting to use it, will this cause harm to the battery?

The main reason for inverting and discharging the battery is the fear that the electrolyte of the battery will flow out. However, the seal of the battery has a rubber cap, the battery water will not flow out easily. In addition, nowadays the battery is generally gel battery, not afraid of inverted and side put, short time are no problem, and will not cause harm to the battery, it's okay, don't worry about it.
