Voltage ripple

- A voltage ripple is a small alternating current on top of a direct current, which results in a DC voltage that is not entirely smooth but ripples slightly. While a battery delivers pure
direct current without any ripple, this is not always the case with a battery charger. In an old-fashioned battery charger, 50 % of the voltage will contain ripples. A large voltage
ripple shortens the lifespan of a battery, which needs to be charged with direct (not alternating) current. In addition, a voltage ripple can interfere with onboard audio, navigation and communications systems.
