Maintenance of DC system chargers and batteries

adv.

Safety & Environment

 When performing battery maintenance, eye wash solution shall be readily available. Battery rooms should be well ventilated. Use bicarbonate of soda solution, 1.0 lb bicarbonate of soda to 1 gallon of water, to neutralize acid spillage. Batteries are heavy and proper lifting techniques should be employed. Much of the battery work is done upstream of any protective breakers or fuses so extreme care should be taken to avoid short circuiting a single cell or battery set. Keep tools insulated. For the protection of our employees and the environment, employees should stay abreast of and adhere to all safety rules, established work practices, and environmental compliance practices while performing maintenance on this equipment.

Battery Inspection:

·        Verify that battery box is in good condition x Inspect the locks, lid, hinges, cable supports and rails to be in good condition. Repair as necessary. x Inspect any fuse blocks, fuses and cables for corrosion, loose connections and deteriorated fuse barrels. Repair as necessary.

·         Inspect the room lighting and ventilation to be functioning correctly. Clean and repair as necessary.

·         Inspect the rack to be clean, free of corrosion, stable and able to support the battery weight. Clean and repair as necessary.

·        Battery Physical Condition Inspection:

·         Inspect battery to be clean, case has no cracks, no leaks and tops are dry and not lifting. Clean and repair as necessary.

·         For clear cases inspect the plates for warping and excessive sedimentation. Document any abnormal conditions.

·         Inspect battery straps to be free of corrosion. Clean and repair as necessary.

·         Inspect battery terminal connections to be free of corrosion. Clean and repair as necessary.

·         Coat all cleaned or replacement connectors, posts, and hardware with a thin film of no-oxide grease.

·         Total  resistance  to be measured , Measured values should be 0.1 milli-ohm.
