Series 55 – Section 8.3 Storage Battery

Section 8.3
Storage Battery

The lead-acid storage battery is an electro-chemical device for storing energy and converting chemical energy into electrical energy.‪

The battery has three major functions:‪

• It provides a source of current for starting the engine.
• It acts as a stabilizer to the voltage in the electrical system.
• It can, for a limited time, furnish current when the electrical demands exceed the output of the alternator.

To avoid injury from battery explosion or contact with battery acid, work in a well-ventilated area, wear protective clothing, and avoid sparks or flames near the battery. Always establish correct polarity before connecting cables to the battery or battery circuit. If you come in contact with battery acid:‪ Flush your skin with water. Apply baking soda or lime to help neutralize the acid. Flush your eyes with water. Get medical attention immediately.

If you come in contact with battery electrolyte:‪

1. Flush your skin with water.
2. Apply baking soda or lime to help neutralize the acid.
3. Flush your eyes with water for 10-15 minutes.
4. Get medical attention immediately.

In the selection of a replacement battery, it is always good practice to select one of an "electrical size" at least equal to the battery originally engineered for the particular equipment by the manufacturer. This information is listed in Table "Table Battery Specification" .‪

Section 8.3.1
Repair or Replacement of Storage Battery

Refer to the OEM for service procedure.‪

Section 8.3.2
Cleaning and Removal of Storage Battery

Precleaning may be necessary. Refer to OEM guidelines.‪

Remove storage battery as follows:‪

1. Disconnect grounded terminal of the battery.
2. Remove the cable clamps.
3. Remove felt washer.
4. Remove the battery.

Section 8.3.2.1
Inspection of Storage Battery

For storage battery inspection procedure, refer to OEM guidelines.‪

Section 8.3.3
Installation of Storage Battery

Install the battery as follows:‪

1. Clean battery carrier, as necessary.
2. Seat the battery level in its carrier.

   NOTICE:
   Do not draw the hold-down clamps down too tightly because the battery case will become distorted or crack.‪

3. Tighten the hold-down clamps evenly until snug.
4. Attach the cable clamps after ensuring the cables and terminal clamps are clean and in good condition.
5. Place a new felt washer at the base of each terminal beneath the cable clamps, to make the cable connections as corrosion resistant as possible.
6. Coat the entire connection with a heavy general-purpose grease.

   Note: Ensure the ground cable is clean and tight at the engine block or frame.

   NOTICE:
   Connect the grounded terminal of the battery last to avoid short circuits, which will damage the battery.‪

7. Check the polarity to ensure the battery is not reversed with respect to the generating system.
