Take note of some of the most common of these hazards and try to avoid them:
Weather - Weather is one of the most common issues associated with shortening car battery life. This is particularly prevalent in areas where the weather gets blistering hot during the summer. During these hot summer months, consider storing your car in the garage, or under covered parking whenever possible to help preserve your battery.
Routine Maintenance - Consider visiting a service center or local auto parts store every few months to get your car battery recharged. This will help it continue running at full capacity and reduce the chance of a gradual reduction in power.
