Climate conditions - In areas with higher temperatures, the actual service life of batteries will be significantly shorter.
The output voltage of the generator - too high can cause overcharging, while too low voltage can cause insufficient charging.
The driving habits of car owners - when the engine is not running, using the electrical appliances in the car for a long time or often forgetting to turn them off.
Incorrect adaptation - selecting a battery with a low capacity will shorten its service life.
Severe vehicle leakage - Severe leakage will significantly increase the burden on the battery and greatly shorten its service life
