Morphology

lead-acid + accumulator

The meaning 'a battery that uses lead and acid' is directly derivable from the components: 'lead-acid' describes the materials (lead + acid) and 'accumulator' means a device that stores electricity. This is a literal, compositional modifier+noun pattern common across languages, so a B1 learner who knows the constituent words should understand the MWE.

Etymology

Lead-acid accumulator shows the literal parts: heavy lead plates and liquid acid inside a container that 'stores energy', so it refers to a battery you can recharge.
