CHECKING
It is recommended to check the following: -cr acks or breaches of the battery box (case);
- the battery upper part cleanness;
- the plugs condition.
It is required to strictly check the following: -lack of plugs sulfate composite;
- proceed, is necessary to their cleaning and greasing;
- check the correct wiring plugs tightening at the battery plugs. The existence of an imperfect
contact may generate incidents at engine starting or at battery charging, sparks producing risk
being possible to occur, which may cause the battery explosion;
- check the electrolyte level.
For the batteries provided with access plugs, which may be dismounted, proceed as follows:
-r emove the plugs;
- check the electrolyte level in each element;
-i f n ecessary , refill the level, using only distill ed water, till maximum 1.5 cm above the plates.
AT TENT ION
N ever fill up with electrolyte, but only with distilled wat er.
PRECAUTIONS
It is important to know that: -the battery contains sulfuric acid which is a dangerous substance;
- during battery charging, oxygen and hydrogen are produced. The mixture of these two
gases is forming a detonate gas, which may lead to the explosion risk.
1. DANGER = ACID
The sulfuric acid solution is a very aggressive, toxic and corrosive product. This is a ttacking
the skin, the clothes and may lead to the corrosion of most of the metals. Also, it is very important, that, when you handle a battery , to consider the following precautions:
- protect the eyes by using protective glasses;
- wear anti-acid gloves and clothes. PARTICULARITIES
