Is it normal for a car not to start after being parked for a week?

[OliveLynn]

It is normal for a car not to start after being parked for a week, most likely due to a drained battery. Here are the relevant details: 1. Car battery replacement cycle: The warranty period for a new car is generally three years or over 100,000 kilometers, and the lifespan of a car battery is approximately three years. After this period, special attention should be paid to the maintenance of the battery, and it should be replaced promptly if necessary to avoid potential hazards. If the battery is used frequently, subjected to heavy loads, or used extensively during this period, its lifespan may be even shorter. 2. Battery: A battery is a type of cell, also known as an accumulator, which works by converting chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte.
