Humidity during the rainy season accelerates corrosion on battery terminals. This buildup can weaken electrical connectivity, affecting overall battery performance and starting power.
Cold and damp conditions slow down the battery’s internal chemical reactions. As a result, the engine may crank slowly or fail to start, especially after the vehicle has been idle for a while.
Rainwater can enter the engine bay through bonnet gaps, particularly when the vehicle is parked outdoors. This exposure can damage the battery and nearby electrical components over time.
Moisture around exposed wires, terminals, or connectors can cause electrical shorts. These shorts drain battery power quickly and may lead to system malfunctions or safety hazards.
If water affects the battery or electrical systems, you may see warning lights or error messages on your dashboard. These alerts often point to moisture-related damage that needs immediate attention.
Pro Tip:
Always try to park your vehicle in a garage or covered area during heavy rain. This helps protect the battery and sensitive electronics from moisture-related damage and ensures longer-lasting performance.
