Yes, it stores power to an extent, but it does not function in the same way as a battery. Capacitors are advertised as a way to store extra current and deliver it to your amplifiers when they pull large amounts of power to stabilize your electrical system and current draw.

PTH Axial Electrolytic Capacitor Axial style capacitors are not used very often but are interesting in how they are marked. A negative or cathode band runs down the side of them similarly to the radial style but there is an arrow in the marking that indicates which side is negative or the cathode.

Capacitors offer some small amount of protection for amplifiers from potentially damaging under-voltage surges over time if you play loud music regularly. But most of the reason for adding capacitors is to keep your car voltage stable.

A: The rule of thumb is to put in 1 Farad of capacitance for every 1,000 watts RMS of total system power. But there is no electronic penalty for using larger value caps, and in fact, many see benefits with 2 or 3 Farads per 1,000 watts RMS. The larger the cap, the more charge is available for the amp when it needs it.

The job of capacitors is to allow only the high frequencies to pass. The inductor (also known as a coil or choke) assumes the opposite task by letting only the low frequencies pass. It does this by storing energy in magnetic instead of electrical form.
