NOTE
Specific gravity measure must not be
performed after battery cell filling.
1- Open the battery cell filling cap.
2- Using the hydrometer, take a sufficient quantity
of electrolyte so that the float emerges. Ensure
the float top does not touch the rubber bulb or
that the foat does not stick by capillarity to the
glass walls.
3- Read the value as indicated on the example
below :
4- Return the electrolyte in the cell and record
cell electrolyte specific gravity on the battery
service log.
5- Repeat operation for each battery cell.

5.1.1 Electrolyte specific gravity and
battery voltage
Specific gravity and voltage measure is the most
important check to be performed on a battery. A
hydrometer is supplied with the work platform.
Specific gravity and voltage readings must be
performed at least once a month and recorded in a
battery service log.
The state of charge of the battery can be checked by
measuring the specific gravity of the electrolyte. This
value decreases as the battery discharges.
When the battery is fully charged, the specific
gravity is 1.280 kg/l.
When the battery is 80% discharged, the specific
gravity is 1.150 kg/l.
The following graphic shows the correspondence
between specific gravity and battery discharge.
Checking electrolyte specific gravity :
Battery electrolyte must not be allowed to
contact the skin or eyes. If it does occur, flush
the contacted area with water and consult a
doctor immediately. Appropiate equipment
must be worn (GLOVES, GOGGLES, RUBBER
APRON) to prevent the electrolyte from
contacting the skin or any other part of the
body during any servicing operation on the
battery.
During maintenance or any servicing
operation on the battery, rings, watches or
any other jewellery must be removed.
