Check for general cleanliness of the battery, mounting rack, and battery
room. Check for electrolyte leaks and cover integrity, and take corrective
action if needed. Check for corrosion at terminals, connectors, racks, and
cabinets. Check the ambient temperature and make sure all ventilation
equipment (fans, vents, etc.) is operable.

Check for cleanliness and operability of eyewash station or portable eyewash
equipment and body wash station (see section 8.2). Check for a class C fire

because of the cooling effect they will have on the battery. Check for
availability of insulated tools and utensils so short circuits can be avoided.

5.7 VOLTAGE READINGS
5.7 VOLTAGE READINGS
An accurate digital voltmeter is critical for extended life of the battery (see
section 1.3). At a constant float voltage, the charging current will increase
as the temperature of the electrolyte increases. Therefore, cells of higher
temperature will indicate a lower cell voltage. See figure 10 for proper
meter probe placement. Place the probes across the posts of the cell so as
not to include the voltage drops across the intercell connections.

Readings of all cells should be taken and recorded about 24 hours after
placing the battery in float. Select the cell/module with the lowest float
voltage as the pilot cell for future readings. Use form POM-133B for all
voltage readings.
