What You Need to Know About Car Battery Voltage
Since voltage is a current, it doesn''t get used up when you use your battery, the way your car uses up gas. However, the frequent generation of power results in the battery''s chemicals slowly turning into different chemicals. Those chemicals are less capable of providing power, and the voltage in the car''s battery will begin to drop.
