Substation Battery Charger Reading

The substation battery check records charger voltage and current on the installed meter and looks at the rack without opening a cell. The technician writes the as-found reading and compares it with the last one on the asset. Do not open a cell, add electrolyte, or enter a live cabinet. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. Record charger voltage and current on the installed meter
  2. Look at the rack, ventilation and any cracked jar you can see without opening a cell
  3. Confirm the eyewash path the site posted, if the room has one
  4. Do not open a cell, add electrolyte, or enter a live cabinet
  5. A charger alarm is a finding, not a field adjustment of a protection setting

Why This PM Exists

The substation battery check records charger voltage and current on the installed meter and looks at the rack without opening a cell. The technician writes the as-found reading and compares it with the last one on the asset. Do not open a cell, add electrolyte, or enter a live cabinet. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

What Skipping It Looks Like

A charger alarm gets cleared by changing a protection setting because the jars 'look fine'. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not open a cell, add electrolyte, or enter a live cabinet.

Setting the interval

Monthly. A charger alarm is a finding, not a field change to a protection setting. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.

Common Questions

How often should this PM run?
Monthly. Monthly. A charger alarm is a finding, not a field change to a protection setting. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.
How long does it take?
Budget about 1.0 hour for a technician working to the standard procedure. ChatterFix uses that estimate for capacity planning, then learns your plant's actual time from completed work orders.
What happens if we skip it?
A charger alarm gets cleared by changing a protection setting because the jars 'look fine'. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not open a cell, add electrolyte, or enter a live cabinet.
