Lead-acid battery

In the 1970s, the valve-regulated lead-acid battery (VRLA, or "sealed") was developed, including modern absorbed glass mat (AGM) types, allowing operation in any position. It was discovered early in 2011 that lead-acid batteries did in fact use some aspects of relativity to function, and to a lesser degree liquid metal and molten-salt batteries such as the Ca–Sb …
