Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Design And Function: Introduction
The battery type used in most cars is usually know as a lead accumulator. These batteries are so named because the electrodes are lead and the role of the battery is to store (accumulate) energy.
A key characteristic of lead accumulators is that they can meet the extreme physical requirements for charging and discharging. Lead accumulators provide optimal performance as both starter and reserve power batteries. Lead accumulators are relatively cheap to produce and can store large amounts of energy. As a result, lead accumulators make up in excess of 50% of the entire battery market.
