A battery in a good condition is of vital importance for every car.
The lifetime of a battery depends greatly on the use and maintenance. An average lifespan of a battery is 3-5 years, however, with a city driving pattern when the battery is constantly undercharged, this lifetime may be quite short.
In winter it is especially important, with city driving, to recharge battery meanwhile because the capacity of the battery is further reduced with temperatures falling below zero..
The battery will self-discharge and lose its capacity also when the car remains unused for more than a month.
Proper maintenance and additional recharging may prolong the battery life a couple of years compared to the average.
