29. How Battery Age Affects Cold Cranking Amps

As a battery ages, its ability to deliver Cold Cranking Amps (CCA) diminishes significantly. CCA is a measure of the battery’s power output at 0°F (-18°C), crucial for starting an engine in cold weather. Over time, the internal components of the battery, such as the lead plates, degrade due to chemical reactions, sulfation, and vibration.

This degradation reduces the surface area available for chemical reactions and increases internal resistance.

Consequently, an older battery, even if it holds a sufficient charge for basic electrical functions, may no longer be able to provide the high surge of amperage needed to turn over a cold engine. This is why older batteries are more prone to failing during winter months. When diagnosing 2013 Ford Explorer battery problems, especially during colder seasons, the age of the battery and its CCA rating should always be considered.

• CCA Degradation: Older batteries have lower CCA ratings.
• Internal Changes: Sulfation and plate degradation reduce power output.
• Impact on Starting: Reduced CCA leads to weak or no cranking in cold weather.
• Winter Vulnerability: Age-related CCA loss is most apparent in cold temperatures.
• Testing: Load tests specifically check CCA capability.

Best For: Understanding the link between battery age and starting power.

30. Battery Venting and Spark Prevention

As discussed in section 25, batteries vent flammable hydrogen gas. Preventing sparks when working around a battery is paramount to avoid a dangerous explosion. The most common source of sparks is by incorrectly connecting jumper cables or when tools accidentally bridge the positive and negative terminals.

It’s also important to note that even turning a key in the ignition can create a small spark if the battery is severely discharged.

When jump-starting, always connect the positive (+) terminal of the dead battery to the positive terminal of the good battery, and the negative (-) terminal of the good battery to an unpainted metal surface on the engine block or chassis of the dead vehicle, away from the battery itself. This final connection is the most likely to create a spark, and by placing it away from the battery, you minimize the risk of igniting any hydrogen gas.

• Risk: Hydrogen gas is explosive.
• Spark Sources: Incorrect cable connections, tool bridging terminals, ignition switch.
• Safe Jump-Starting Procedure: Connect positive to positive, negative to ground on the dead vehicle.
