Separator
An insulator between the positive and negative plates in a battery that prevents the two plates from touching, thus preventing a short circuit.
In addition, the separator can be used to protect the plates from vibrations, making a battery particularly resistant to vibration. For this purpose, separator pockets are used in super heavy-duty batteries, which completely enclose the grid plates. In AGM batteries, the separator made of glass fiber fleece absorbs the electrolyte, which improves the cycle stability and reduces the internal resistance, and particularly high cold start performance is achieved.
