⑤
Unloaded Voltage: The voltage measured when turning off
the on-board electrical appliances
⑥
Ripple: A vehicle's battery operates on one-way direct current
(DC) electricity, while alternators output alternating current
(AC) electricity. In this process, the power needs to go through
the diode rectier to turn into a direct current - that's when
the ripple occurs
