Crown Battery 125S

As is true with any piece of industrial equipment, proper maintenance not only keeps it operating to its design specifications, but also helps prolong the equipments life. The following effective battery maintenance tips can help achieve the best performance out of your industrial battery

1. Maintain the proper electrolyte level. Avoid overfilling

2. Charge properly, check charger controls and instruments periodically. Calibrate meters as needed

3. Repair any damage promptly. Minor damage, if not repaired in a timely manner, can lead to major damage

4. Don't overcharge, many batteries deliver short service life from too much charge

Warning: This inspection requires trained personnel with PPE!

Is the battery still in the vehicle?

If the battery is still in the vehicle, turn off the power switch and unplug the battery from the vehicle

Allow the battery to remain on open circuit (do not charge or discharge) for 30 minutes or longer

Fill in the Crown Battery Inspection Report. Include battery type, serial number, etc.

Read and record the specific gravity for all cells of the battery

Read and record the open circuit voltage for all cells of the battery

Read and record the pilot cell temperature

Record the temperature-corrected specific gravity readings. Use a temperature correction thermometer.

- Lead Acid Motive Power Batteries can become unbalanced or sulfated if they are not recharged or equalize charged on a regular basis

Likewise over-discharging or unbalanced discharge can cause low uneven cell voltages. The treatment for restoring the battery to its full potential involves charging and discharging the battery in a very tightly controlled manor

This is a last resort remedy in order to salvage a battery that's been allowed to get into this condition. This may or may not be successful, as sulfate is extremely hard to remove from the cell plates and if let in this condition, may not be reversible

A. Charge the battery as normal to a fully charged condition.

B. Record all individual cell voltages and specific gravities. These readings will be used later to measure how successtul the treatment was.

C. Starting with a cool (less than 80°F) fully charged battery, charge the battery at 2.5 amps per 100 amps of battery capacity. A 24-85FC-21 has a capacity of 850 A.H. Therefore the charge rate would be 21 amps. Charge the battery for at least 24 hours. Stop the charge, if the battery temperature goes to 120°F or higher.

A. Let the battery cool back down to about 80°F

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

Sign off on the battery maintenance

Warning: This procedure requires trained personnel!

Enter the current battery charge in amperes

Place the battery on charge at every opportune time (breaks, lunches, etc)

Enter the battery charge after opportunity charge

Opportunity Fast Charge will allow you to charge a battery up to 80% in two hours or less

Enter the battery charge after Opportunity Fast Charge

Is the charger rated higher than the connector on the battery?

If yes, battery modifications will be needed. These modifications include but are not limited to; dual cables, dual intercell connectors, cooling fans, battery recording device, thermistors and pilot contacts
