What Long does differently

Long batteries combine large-scale production with ISO quality standards and a batch-to-batch consistency that has made them the de-facto standard in backup systems and electric mobility. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Usage and maintenance tips

In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge.

Warranty and coverage

The Long 36B20R comes with the manufacturer's official warranty against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.
