Design And Function: Introduction
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
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.
