AutoZone Has the Best Battery Components 
When your vehicle's battery doesn't work, everything grinds to a halt. Nothing else matters until you restore power and bring your vehicle's systems back to peak performance. The problem's even worse when you're trying to power your vehicle's normal assemblies plus extra equipment such as a winch or auxiliary lighting. Fortunately, AutoZone's got you covered. We stock the best battery current control systems for cars and trucks sourced from top brands such as Painless and Westin.

How Your Battery Current Control System Works
As it's typically made, a vehicle battery can handle the standard current requirements to power the starter, alternator and other key systems such as climate control. With a truck or off-road model such as a Jeep, you need a finely tuned power system to operate other accessories installed onto the vehicle. That's where a battery current control system comes into the picture. Designed to accommodate a concurrently installed second battery, a control system allows the driver to control power usage by auxiliary systems that depend on the second battery. That's especially important, considering that winches and other accessories often rely on marine-quality power cells to operate. For winches, the common battery power recommendation is between 440 and 660 cold cranking amps.
