The battery gymnastics are required

The storage battery of car BMW of 3 series has the built in index of degree заряженности batteries (the marksman on an illustration), located on the top party of the battery. This “the magic eye” can show, of course, only the basic condition заряженности.

The battery does not demand service. Addition of the distilled water is not required. Electrolit level can be defined outside. It is in area marks MAX-1, approximately on 5 mm above lead plates.


Check of level of electrolit (at the batteries demanding service)

If the storage battery not firms BMW it is a question, as a rule, about so-called малообслуживаемой to the battery is bought. In this case, if electrolit level falls below mark MIN, it is required to add one-two time in a year the distilled water. All sections of the battery should have the identical level of electrolit which are between marks MAX and MIN.

Electrolit level is checked necessarily outside. If it is impossible to make it, remove carving covers and glance in section from above. Electrolit level should be on 5 mm above lead plates.
