The Extralink battery is a 12-volt AGM battery with a capacity of 7 ampere hours. It is a device designed to store energy, which can be repeatedly discharged and recharged with electricity.
More and more often they replace well-known acid or alkaline models because of their properties, such as:
no special maintenance or electrolyte refills required
the rooms where the batteries are installed do not need additional ventilation
they perform well in buffer operation - their service life is up to 5 years
lower internal resistance and higher energy efficiency - compared to traditional batteries
Much lighter and smaller than acid batteries, with the same capacity
more resistant to extreme temperatures, vibrations and shocks
VLRAs are batteries that do not emit gases under normal conditions and retain their tightness. This means they do not need to be installed in special ventilated rooms. They can be installed and used in any position. The reduction of electrolyte leakage outside the housing significantly reduces corrosion in the battery's operating environment and has a positive impact on environmental protection.
