A type of plastic insulator enclosing each positive plate in the cell. The roll of the separator is to separate the positive and negative plates from each other and to catch particles that detach from the positive plate to avoid short-circuits.
For AGM-batteries, the pocket separator consists of a thin fibre-glass mat (AGM = Absorbed Glass Mat).
