All Subaru vehicles are equipped with maintenance-free batteries. The
term "maintenance-free" can be misleading - as these batteries do
require some attention to maintain their cleanliness and efficiency.It is extremely important to have your car's battery checked by a Subaru-trained technician regularly.
A battery check will include an examination of cable connections for
cleanliness and tightness. Loose or corroded connections can
dramatically diminish your car's starting power; and if the connections
grow loose or crusty enough, they can shut off your car's electrical
flow entirely and leave you thinking you have a dead battery.
High temperatures also reduce the efficiency at which a battery is recharged.
driving conditions frequently require the use of A/C for extended
periods while driving at slow speeds. This additional load requires the
charging system to work properly so that it sufficiently charges the
battery the next time you start your car's engine. For this reason, your
Liberty Subaru service technician should also check your battery's charging system and
voltage regulator, and inspect your vehicle's alternator to ensure that
all components are operating properly.
