Lead-acid batteries are an older technology used mostly as car batteries (gasoline-powered cars, to start the engine). Could they help solve the [[energy storage]] problem? | Lead-acid batteries are an older technology used mostly as car batteries (gasoline-powered cars, to start the engine).

If you have some extra car batteries, may as well use them for a [[rooftop solar]] project. They probably won't store enough energy to power your whole home, but it's better than nothing.
