7.2.4 Basic requirements and pre cautions on maintenance routines :
1) Principle to discover areas of concern and insure the safe operation. Should be documented
while test ing the batter ies .
2) Preventative maintenance and performance analysis should be carried out routinely .
3) Battery parameter and operation should be complied with the maintenance documentation and
re viewed .
4) Always wear insulated gloves when handling the batteries to avoid electric shock. Make tools
and instrument s are properly insulated.
5) Use calibrated instrument and meters which meet test requirement.
