Maintenance 7
Cleaning the battery
Cleaning the cell array, battery tray and insulators is necessary in order to
maintain the required insulation of the cells against each other, against
ground or foreign, conductive objects. In addition, damages and accidents
from corrosion and leakage currents are avoided.
Leakage currents can arise if the dust deposits on the battery combine
into a conductive layer with small amounts of electro-particles, which may
leak when charging the battery. Leakage currents then flow
through this layer.
Weak leakage currents can result in the self-discharge of individual cells
or of the battery (reduced capacity).
Electrical sparking cannot be ruled out if higher leakage currents flow.
This sparking can cause explosive gas, which issues from cells when
charging the battery, to explode.
Safety instructions
Risk of injury due to chemicals!
The batteries contain acids, which are poisonous and corrosive. This is
why batteries can release explosive gases that can explode if they ignite.
The squirting battery acid can then cause serious burns.
► Read and observe the Operator’s Manual of the battery.
► Observe the manufacturer's cleaning instructions.
► Do not smoke, avoid fire and open flames.
► Do not use any heating devices with open flames.
► Avoid contact of the battery acid with the skin, eyes and mouth.
In case of contact with battery acid, immediately flush the
contaminated parts of the body with plenty of clear water and seek
medical attention at once.
► It is essential to wear protective clothing and goggles when working on
batteries.
► When cleaning, use a dry cleaning cloth.
► Do not remove or open cell plugs.
Accident hazard from dirty battery!
A dirty battery can lead to short-circuits or leakage currents and thus to
serious injury or even death.
► Keep the battery clean.
