Which statement regarding vehicle batteries is accurate?

The statement regarding vehicle batteries that is accurate indicates that vehicle batteries can run down if stored for long periods. This occurs because batteries naturally discharge over time, especially when not in use. In addition, factors such as temperature fluctuations and the self-discharge rate of the battery can lead to a reduction in charge even when a battery is stored. For this reason, vehicles that are not frequently used, such as classic cars or seasonal vehicles, should be periodically charged or connected to a trickle charger to maintain battery health.

The other options do not accurately reflect best practices or facts regarding vehicle batteries. Disconnecting battery cables while the engine is running, for instance, can cause electrical surges that may damage the vehicle’s electronic systems. While some batteries may offer warranties, not all have lifetime warranties, and battery warranties can vary widely in terms of duration and conditions. Additionally, battery maintenance is still important in warmer climates as higher temperatures can accelerate the chemical reactions within batteries, leading to a shorter lifespan if not properly maintained. Thus, the importance of regular checks and potential maintenance does not diminish in warmer weather.
