1. Parasitic Drain: Even when a car is turned off, there are still some electrical systems that continue to draw power, such as the car alarm, clock, and memory systems. This is known as parasitic drain. Over time, this drain can deplete the battery, especially if the car is not driven regularly.
2. Sulfation: When a lead-acid battery is left in a discharged or partially discharged state for an extended period, the lead sulfate crystals on the battery plates can grow and harden, making it difficult for the battery to hold a charge. This process is called sulfation and can permanently damage the battery.
3. Temperature: Extreme temperatures, both high and low, can affect battery performance and longevity. If the car is parked in a hot environment, the high temperatures can accelerate the evaporation of water from the battery, leading to dehydration and reduced capacity. On the other hand, cold temperatures can slow down the chemical reactions within the battery, making it less efficient in delivering power.
To prevent the battery from going flat, it's recommended to start and run the car for at least 15-20 minutes every week or two. This helps maintain the battery's charge and prevents sulfation. Alternatively, you can connect the car to a battery charger or maintainer to keep the battery topped up.
