Climate
Extreme temperatures can shorten the life of a battery. In hot climates, the heat can cause the battery to overheat and lose its capacity. In cold climates, the cold can make it difficult for the battery to start the vehicle.
Frequency of use
The more frequently a vehicle is driven, the more the battery is used. This can shorten the life of the battery.
Type of battery
There are two main types of batteries used in vehicles: lead-acid batteries and AGM (absorbed glass mat) batteries. AGM batteries are more resistant to extreme temperatures and vibration than lead-acid batteries. They also have a longer life expectancy.
