The document is a battery safety and maintenance guide from Deka Batteries. Here’s a summary of its key points:

1. Safety Precautions

  • Batteries contain lead and sulfuric acid, which can cause serious health issues.

  • Always wear eye protection and work in well-ventilated areas.

  • Hydrogen gas from batteries is explosive—avoid sparks, flames, and smoking.

  • Disconnect the grounded cable first and reconnect it last to prevent sparks.

2. Battery Inspection & Maintenance

  • Before testing, check for cracks, leaks, loose connections, and corrosion.

  • Clean corrosion with a baking soda and water paste.

  • Use a voltmeter to check the state of charge.

  • Charge weak batteries before performing load tests.

3. Charging Guidelines

  • Never charge a frozen battery; allow it to warm first.

  • Overcharging shortens battery life—follow manufacturer instructions.

  • Gel and AGM batteries require special chargers.

  • Charge at 1/3 of the reserve capacity rating and avoid exceeding 16 volts.

4. Battery Installation

  • Mark and disconnect cables properly before removal.

  • Clean terminals before installing a new battery.

  • Tighten connections properly—do not over-tighten.

  • Coat terminals with corrosion protection spray.

5. Testing Methods

  • Load Testing: Determines battery performance under load.

  • Conductance Testing: Predicts battery health based on electrical response.

  • Hydrometer/Voltage Testing: Checks charge state and battery condition.

6. Jump-Starting Procedures

  • Follow the correct order when connecting jumper cables:

    1. Positive (+) to Positive (+)

    2. Negative (−) to engine block (away from the battery)

  • Avoid connecting to moving parts or fuel lines.

7. Battery Storage & Stock Rotation

  • Store batteries in a cool, dry place, upright.

  • Follow First In, First Out (FIFO) rotation to use older stock first.

  • Test and recharge stored batteries every 4-6 months.

8. Selling & Selecting the Right Battery

  • Sell based on cranking amps, not just warranty period.

  • Consider temperature effects—cold climates require higher cranking power.

  • Vehicles with high electrical loads need a stronger battery.

This guide emphasizes safety, proper handling, testing, and maintenance to extend battery life and prevent hazards. Let me know if you need a more detailed breakdown!
