Study sees gradual, focused replacement of lead-acid SLI batteries by Li-ion batteries over next couple of years

Green Car Congress

The researchers also concluded that the energy market sector and its use of the lead-acid battery will continue to grow with significant expansion in use for storage in renewable energy systems. There will still be a need for a 12 V battery for the supply of auxiliary power that will not necessarily be a Pb-acid SLI battery.
