Click here to order! Your BMW E46 is equipped with a 6-cell volt lead acid battery. Each cell consists of lead plates in a lattice and completely covered with sulphuric acid the electrolyte.

The chemical Bosch S5 Battery 100Ah Electrical System Part Fit BMW 3 Series E46 1999-2006 between lead and sulphuric acid produces a nominal 2 volts per cell; the six-cells together provide the approximately 12 volts required to operate electrical and electronic components in the vehicle. After the battery is used to start the engine, the alternator powered via the engine accessory belt takes over electrical generation and also Bosch S5 Battery 100Ah Electrical System Part Fit BMW 3 Series E46 1999-2006 the charge that the battery used in starting the engine.

During operation and also during recharging, the chemical reactions in the battery produce heat, which causes the electrolyte sulphuric acid to evaporate. The cells in many older batteries are equipped with plastic caps, which allow the evaporated electrolyte to escape. If the level of electrolyte drops below the tops of the lead plates, the plates can become damaged; also the heat in the battery begins to build excessively at that point.

If your battery had removable cell Bosch S5 Battery 100Ah Electrical System Part Fit BMW 3 Series E46 1999-2006, be sure to remove them periodically and inspect the electrolyte level.
