4.2 Operation

4.2.1 Commissioning unfilled batteries

Z The operations required must be carried out by the manufacturer's customer

service department or a customer service organisation authorised by the

manufacturer.

4.2.2 Commissioning filled and charged batteries

Checks and operations to be performed before starting daily work

Procedure

• Make sure the battery is in physically good condition.

• Make sure the terminals are correct (positive to positive and negative to negative)

and check that contacts on the battery terminal conducting system are secure.

• Check the terminal screw torques (M10 = 23 ±1 Nm) of the terminal conductors and

connectors.

• Charge up the battery.

• Check the electrolyte level.

Z The electrolyte level must be above the cell baffle or the top of the separator.

• Add electrolyte with distilled water up to the nominal level.

Checks completed.

4.2.3 Discharging the battery

Z To achieve an optimum useful life avoid operational discharge of more than 80% of

nominal capacity (full discharge). This corresponds to a minimum electrolyte

density of 1.13 kg/l at the end of the discharge. Recharge a discharged battery

immediately.
