PROCEDURE FOR MAINTENANCE OF BATTERY

THE EXACT NATURE OF WORK THAT ARE TO BE CARRIED OUT AS FOLLOWS:

   A)    Batteries are to be cleaned properly, each individual cell is to be cleaned thoroughly along with racks and cabinet.

   B)    Check and clean the battery vents.

C)    The battery leads inter cell connections etc are to be checked for tightness and treated (Greasing) check all connections if necessary replace them.

D)   Check electrolyte level and if required, top up with fresh electrolyte up to correct level(Consider the manufacturer recommendations)

E)     Measure the density using Hydrometer and note down the result.

F)     Check the in line voltage of each cell with properly scaled in line voltmeter and record reading.

Note: If the result as above (Item No:”E&F”) shows that any of the cells is weak, they are to be replaced with new ones.

G)   Clean the battery compartment and the battery Charger unit,check all the Circuits and components of the battery charger and ensure correct operation of charger in all conditions i.e. at high rate and low rate,check all meters and indication lamps for proper operation,replace the burnt out items as necessary,after the maintenance,the charger is to be put on low rate charging and should not be left on high rate charging.

          

H)    Check whether the DC supply reaches the switchgear panel or not,if any interruption is noticed,replace the wiring between the battery unit and the switch gear panel.
