Crown Battery 18-125S-15

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 from the battery

Check for any signs of tray corrosion

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

Spot check the electrolyte levels periodically to determine if the proper levels are being maintained

Check uniformity of construction and content in each cell

Check if some cells take less charge than others

Check if cells with a lower state of charge are up to the same level as the others after equalizing charge

Check if cells with a higher state of charge are somewhat overcharged to bring the cells with a below normal state of charge up to full charge

Select the frequency of equalization based on how often the batteries are cycled and the depth of the cycles

Check if unnecessary equalizing charges are avoided to prevent significant loss of battery life caused by overcharge

Sign off on the battery maintenance

Warning: This procedure involves handling of corrosive substances and should only be performed by trained personnel with appropriate PPE.

Check for minor spills or overflows of electrolyte

If minor spills or overflows are found, clean with rags or paper towels and dispose immediately.

Check if the top of the battery is dirty or looks damp

If the battery is dirty or damp, it is ready for a general cleaning.

General cleaning involves Powerhouse Cleaner's 3 Step Process (Corrosion Remover, Battery Cleaner, Rinse)

Apply Powerhouse's Corrosion Remover on corroded areas and let sit for at least 10 minutes

Apply Powerhouse's Battery Cleaner across the entire battery and let sit for at least 10 minutes

Rinse the battery after the Corrosion Remover and Battery Cleaner have both sat for at least 10 minutes

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

Sign off on the battery replacement

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)
