With the 21st century technology loaded in today’s vehicles it is more important than ever to ensure that your battery stays charged and on point.  Old worn batteries will often still start up the engine but will cause other problems. When you start the engine of your vehicle, the starter motor puts a huge load on the electrical system. Even though the car may sound normal as it starts, it’s the load on the starter that can make the system voltage drop well below normal if the battery is already getting weak.  Low voltage can cause issues with the many computers and modules in your car that depend on a stable voltage. Because of this, at Delta Tire & Lube we recommend replacing car batteries today as preventive maintenance more than ever before.
