Temperature change and hot summers are hard on batteries and when the temperature rises or drops it can cause a weak battery to fail. Battery cables and terminals should be cleaned and inspected periodically to make sure they provide a good electrical connection. Have your battery checked in the fall because it usually is in the winter when it will let you down. Cold weather can severely affect the cranking power of a battery.Your technician can test the battery’s strength and recommend a replacement if it’s too weak. Along with the battery, the cables, wires and terminals around the battery should be inspected for corrosion, fraying and cracks.
