Set of sockets 10mm, 13mm E6 varyflathead screwdriver Applicable Models: Need to buy parts for this project? 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 Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 completely covered with sulphuric acid the electrolyte. The Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 Syste between lead and sulphuric acid produces a nominal 2 Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 per cell; the six-cells together provide the approximately 12 volts required to operate electrical and electronic components in the vehicle.

After the battery Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 used to start the engine, the alternator powered via the engine accessory belt takes over electrical generation Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 also replenishes 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 BW 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 Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 to build excessively at that point.

If your Vetsch had removable cell caps, 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 Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 of the battery using a Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 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 Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 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 Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 will neutralize acid deposits and clean the top of the battery and the Vetech Battery 70Ah Electrical System Part Fit BMW 3 Series E46 1998-2006 compartment.
