The Importance of Your Car Battery

Your car battery plays a crucial role in the overall functionality and reliability of your vehicle. It serves as the electrical power source, providing energy to start the engine, operate the lights, power the electronics, and more. A properly functioning car battery ensures a smooth and consistent supply of power to all components, allowing for a seamless driving experience. Regular battery maintenance, such as checking the connections and ensuring proper charging, is essential to prevent unexpected breakdowns. Remember, a healthy battery is vital for starting your car and powering its electrical systems, so prioritize its maintenance to avoid inconvenient and potentially costly issues down the road. 

Your Vehicle’s Battery

Todays batteries in cars, SUVs and light trucks are required to start the vehicle through the wide varying extreme weather conditions in New Hampshire and Maine and run all of the power-hungry accessories. Today’s start/stop  fuel savings techniques add further demands on your starting system and battery. Auto Care Plus’s MT Series Interstate Automotive / Light Truck Batteries as well as the MTP Platinum are built to handle cold weather starts as well as warm weather battery stresses. They are specifically designed to provide maximum cranking power to start the vehicle and run the electronic accessories when the vehicle is turned off. Backed by a nationwide 30 month free-replacement and 48 month pro rated warranty, all Interstate Batteries are engineered to meet exact OE fitment specifications.
