Generators and batteries do not last forever. 

Generators and batteries do not last forever. Each has its own lifespan. The service life of a car battery is from 2 to 5 years, depending on how often and how long you drive, as well as the temperature in your place of residence. Batteries last longer in cold conditions and less in hot ones. Generators last an average of 7 years or 150,000 km.

The Autostart company repairs and replaces starters and generators. Checks the battery with special devices.
