Your 1985 Chevrolet G20 cannot function without a battery. The battery provides power for starting your vehicle and also acts as a surge protector for the car’s computer. You can get short-term power as well for things such as lights, stereo, GPS, or wipers when your engine is off.

When your 1985 Chevrolet G20 has plenty of add-on’s and upgrades, it will call for more power than a factory standard vehicle. In these cases, it is highly recommended to upgrade your battery to a high-performance battery. A high-performance battery also generally has a higher power capacity with a charge ability that is denser and can put out more amps. Additional benefits of a high-performance battery include; faster speeds, longer distances, and faster starting.
