The Extralink battery is a 12-volt AGM VLRA battery with a capacity of 40 ampere hours. The battery is a device designed to store energy, which can be repeatedly discharged and recharged with electricity.
In AGM VLRA batteries (Valve Regulated Lead Acid) the electrolyte is absorbed in a glass mat separator.

More and more often they replace well-known acid or alkaline models because of their properties, such as:
no special maintenance or electrolyte topping up 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
