Crown Battery 125S

Warning: This procedure requires trained personnel with PPE!

Check for any breaks in the coating of the steel tray

Check for any accumulation of dampness or acid on the battery

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

Enter the frequency of equalization

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

Select the battery operation type

Check if batteries are kept healthy by equalizing them according to the selected operation type

Warning: This procedure involves handling of corrosive substances. Ensure you are wearing 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.

Is the top of the battery dirty or damp?

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

Use Powerhouse Cleaner's 3 Step Process for general cleaning.

Spray Powerhouse's Corrosion Remover onto the corroded areas

Let the Corrosion Remover sit for at least 10 minutes.

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

Old battery removed successfully?

New battery installed successfully?

This is the complete recharge of a battery after it has been fully or partially discharged during normal operation. In general, a cycle charge is based on an 8‐hour charging cycles, but can be extended, depending on need

A freshening charge is used to bring a battery to a fully charged condition before it is placed in service or when it has been standing idle for a short period. It takes about three hours at the finish charge rate (3‐6 amperes per 100‐ampere hours of the battery’s 6‐hour capacity rating)

When a battery is placed on charge, the opposite action of battery discharging takes place; the sulfate in the active material of the plates is driven back into the electrolyte

This reduces the sulfate in the plates and increases the specific gravity of the electrolyte and the electrochemical process continues until the on-charge cell voltages reach 2.50 to 2.70 volts per cell, depending on the type of charging equipment used

Finish rate or "normal" rate is that current which can be used safely any time charging is required and which can be continued after the completion of the charge without causing excessive gassing or high temperature resulting from overcharge. The finish rate is shown on the nameplate of Crown Batteries

Generally, the finish rate is 3.5 amperes per 100 hours of the battery's 6-hour rated capacity. A partially or completely discharged battery can safely handle currents much higher than the finish rate, but as it approaches full charge, whatever charging rate is used must be reduced to the finish rate
