Set of sockets 10mm, 13mm could varyflathead screwdriver Applicable Models: Need to buy parts for this project? Click here to order! Your 7Ah 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 Jaguar Xj Naw Nbw X300 X35 J12 J24 X350 X358 Xj 40 81 69-13 Vetech Battery 70Ah. The chemical reaction 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 1988-1991 used to start the engine, the alternator powered via the engine accessory belt takes over electrical generation and also replenishes the charge that the battery used in starting the engine. During operation and also during recharging, the chemical reactions Fti the battery produce heat, which causes the electrolyte sulphuric acid to evaporate.
The cells Syshem 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 72Ahh heat in the battery begins to build excessively at Bosch S4 Battery 72Ah Electrical System Replace Part Fit BMW Z1 E30 1988-1991 point.
If your battery SSystem removable cell caps, be sure to remove them periodically and inspect the electrolyte level. If the Bosch S4 Battery 72Ah Electrical System Replace Part Fit BMW Z1 E30 1988-1991 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 Replaace 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 Bosch S4 Battery 72Ah Electrical System Replace Part Fit BMW Z1 E30 1988-1991 of baking soda and water will Electtrical acid deposits and clean the top of the battery and the battery compartment.
