Vehicle Battery

Battery Change and Battery Ventilation

• When replacing the vehicle battery pay attention to that there is no open bleed hole in the area of the positive terminal.
• If there is an open bleed hole in this area it must be closed using a seal and the ventilation in the area of the negative terminal must be opened.
• Pay attention to the battery type. Correct designation of the battery. Refer to the Parts Information.

Severely Discharged Batteries

• Severely discharged batteries freeze earlier.
• Batteries that have been frozen must no longer be used.
• Severely discharged batteries in vehicles must be replaced prior to delivery. Pre-existing damage cannot be ruled out.
• Batteries which have not been in driving mode for a longer time, for example with vehicles in storage, discharge by themselves.
• For severely discharged batteries, the electrolyte consists almost completely of water, because the acid portion has been greatly reduced.
• Severely discharged batteries are sulphating, that means that the entire panel surfaces harden.
• The sulfating process may be largely reversed if a severely discharged battery is recharged immediately.
• If the battery is not recharged, the plates will continue to harden, and the ability to accept a charge will decrease. This results in reduction of battery performance.
