negative terminal

Polarity element connected to the negative plates and attached to an electric cable, which connects the battery to the electric circuit.

battery cover

Upper part of the battery, sealed in the case.

positive terminal

Polarity element connected to the positive plates and attached to an electric cable, which connects the battery to the electric circuit.

plate grid

Hole in the plate coated with a porous lead-based paste that reacts in the acid solution.

positive plate

Electrode made of honeycombed lead oxide; it supports the active matter (paste) and collects the current.

negative plate strap

Component holding the negative plates together.

positive plate strap

Component holding the positive plates together.

liquid/gas separator

Ventilation device retaining the acid vapors and preventing liquid from being discharged.

separator

Porous partition separating the negative and positive plates in order to prevent short circuits.
