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. If the electrolyte is at the same level as the tops of the lead plates, add clean distilled water to the battery. Most modern lead-acid batteries are sealed so that the evaporated electrolyte cannot escape.
However, a charging battery also produces hydrogen. This is discharged from the top of the battery using a small vent tube. Make sure the vent tube is not blocked or damaged and keep in mind that open flames or sparks around a charging battery are a potential source of battery explosion.
Heat, chemical reactions and electrical charges can cause battery connections to become covered with corrosive and insulating deposits. Any time you remove the battery terminals from the battery, be prepared to clean the metal surfaces with a metal brush. A solution of baking soda and water will neutralize acid deposits and clean the top of the battery and the battery compartment. Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement.
The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and Bosch S5 Battery 100Ah Electrical System Part Fit BMW 3 Series E46 1999-2006.
