Acumulator AGM 12v 18Ah
The Extralink AGM 12V battery is a 12-volt battery with a capacity of 18 ampere hours. The battery is an energy storage device that can be discharged and recharged several times.

In AGM VLRA batteries (Valve Regulated Lead Acid) the electrolyte is absorbed in a glass mat separator.

VLRAs are batteries that normally do not emit gases and remain tight. This means they do not need to be installed in special ventilated rooms. They can be placed and used in any position. The reduction of electrolyte leakage outside the casing significantly reduces the corrosion process in the battery's operating environment, which has a positive impact on environmental protection.
