Crown Battery 18-85-21

Warning: This procedure requires trained personnel with PPE!

Check for any breaks in the coating of the steel tray

Check for any sulfuric acid spill on the battery

Check for any signs of tray corrosion

Check for any accumulation of dampness or acid

Check the electrolyte level of two or three cells each time the battery is changed

Add water to all of the batteries assigned to each charging area on a regular time schedule

Check uniformity of battery cells

Enter the state of charge of the cells

Check if cells require equalizing charge

Note: Unnecessary equalizing charges can result in significant loss of battery life caused by overcharge.

- To prevent corrosion and the resultant problems, batteries must be cleaned and dries routinely

Sometimes minor spills or overflows of electrolyte occur due to overfilling. Instead of giving the battery a general cleaning at this time, the moisture can be removed with rags or paper towels. (This should be immediately disposed of.)

The frequency of a general cleaning depends upon two factors:

1. How quickly dust, dirt, oil, and other foreign matter accumulates on the top of the battery, and 2. How quick the electrolyte spillage accumulates

When the top of a battery is "dirty" or looks damp, it is ready for a general cleaning. It could be as often as every two weeks or as infrequent as every six months, depending on the battery's environment and the care it receives. The average battery needs general cleaning every three months

To give a battery a general cleaning, use Powerhouse Cleaner's 3 Step Process (Corrosion Remover, Battery Cleaner, Rinse)

Powerhouse's Corrosion Remover was developed specifically for the removal of heavy corrosion and acid neutralization. For use, spray onto the corroded areas (will turn a rust looking color) and let sit for at least 10 minutes

Powerhouse's Battery Cleaner is a mixture of 2 parts cleaning detergent to 1 part acid neutralizer. Battery Cleaner is OSHA compliant and environmentally safe. For use, spray across the entire battery and let sit for at least 10 minutes

After the Corrosion Remover and Battery Cleaner have both sat for at least 10 minutes the battery can now be rinsed. The corrosion and acid should be neutralized and can be washed down the drain (note if lead pieces from the top of the battery are in the water they should be disposed of properly.)

Warning: Battery replacement should be done by trained personnel only!

Battery fully or partially discharged during normal operation?

Enter the battery's 8-hour charging cycle

Enter the finish charge rate (3‐6 amperes per 100‐ampere hours of the battery’s 6‐hour capacity rating)

Enter the on-charge cell voltages (2.50 to 2.70 volts per cell)

Enter the finish rate (3.5 amperes per 100 hours of the battery's 6-hour rated capacity)
