Determining if a Battery is Properly Charged

- 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.)

CAUTION: ONLY EXPERIENCED PERSONNEL SHOULD ATTEMPT BATTERY REPAIRS! ALWAYS WEAR SAFETY GLASSES AND A FACE SHIELD WHEN WORKING ON OR NEAR BATTERIES

Choose the action based on the battery's condition

If you don't have an experienced battery repair person, send the battery to your nearest authorized Crown Battery repair facility or arrange to have a Crown Battery service technician perform the repairs at your plant site

- Test batteries using three testing instruments

- The specific gravity and open circuit voltage readings are normally in direct proportion to each other; consequently, a voltmeter or hydrometer can be used to check the battery

- The use of the voltmeter is a faster method of approximating the individual cell state of charge and can reduce dramatically the time required for routine battery checking. When using the voltmeter method, take specific gravity readings on the two cells having the highest and lowest voltage readings

- This will confirm both cells state of charge and accurately pinpoint the difference in the state of charge between them. The voltmeter is used when on‐charge or on‐discharge voltage readings are needed

- A battery thermometer is read like a normal thermometer. A proper thermometer should have specific gravity correction marked on its scale

- The hydrometer has an extra‐long scale to make readings more accurate. For ease of correcting for temperature, the specific gravity corrections are marked on the scale of the thermometer. The cell tester (voltmeter) has a 1.5 to 3.0 volt scale and an easy‐to‐handle, one‐piece terminal probe;

Warning: This procedure requires trained personnel with PPE!

Is the battery water level low?

If water level is low, proceed with the following steps. If not, skip to step 8.

If tap water is not pure, use distilled water.

Enter the amount of water added to the battery.

Did you avoid overfilling the battery?

Is there any visible tray corrosion?
