There is an effort by some car makers to shift to a 48 volt system rather than 12 volt system. If this were chosen for an electric car, the lead-acid battery would then be 48 volts rather than 12 volts. The need is the same - to have a battery pack meant to maintain voltage, whether 12 volt or 48 volt, for the on-board car systems just named.

According to a 2003 report entitled "Getting the Lead Out", by Environmental Defense and the Ecology Center of Ann Arbor, Michigan, the batteries of vehicles on the road contained an estimated 2,600,000 metric tons (2,600,000 long tons; 2,900,000 short tons) of lead. Some lead compounds are extremely toxic.
These batteries are commonly referred to as SLI (starting, lighting, and ignition) batteries, reflecting their primary functions in a vehicle. The active circuit parts of a lead-acid battery cell include several components. The negative electrode is made of lead (Pb), while the positive electrode is made of lead dioxide (PbO2).
While they offer proven safety, lead-acid batteries have a lower specific energy compared to lithium-ion types. In contrast, hybrid electric vehicles often use nickel-metal hydride (NiMH) batteries because of their long lifespan and ability to undergo many charge/discharge cycles.
