Some Subaru Outback owners report experiencing dead battery issues during winter storage, characterized by symptoms such as slow engine cranks, no starts, dim lights, flickering dashboard lights, and clicking noises when attempting to start the engine. To mitigate these problems, they recommend using a portable jump starter or jumper cables and being mindful of parasitic drain, which can occur when power is drawn from the battery even when the vehicle is off.
