Acumulator VRLA Alarmtec BP 18-12 (12V, 18Ah)

Alarmtec BP 18-12 is a maintenance-free valve-regulated lead-acid battery (VRLA). It is hermetically sealed; the gases released during the charging process recombine to form water, which eliminates the need for its regular addition. The battery uses AGM (Absorbed Glass Metal) technology, where the electrolyte is absorbed in highly porous fiber glass separators placed between the plates.The absence of a liquid electrolyte allows it to work in any position. A low internal resistance enables a higher voltage and longer operating time.The battery is dedicated for use in buffer power supplies. It can also be used as a cyclically recharged power source for autonomous or portable devices (charging voltage 14.1...14.4 VDC).Key features VRLA battery - maintenance free, does not require the addition of water or electrolyte, can work in any position, designed lifetime of 3 - 5 years (at 20oC according to Eurobat) small size, slow self-discharge.Discharge characteristicsSelf-discharge characteristics (where the X axis represents months)DimensionsPlease note:The battery needs to be fully charged every 6 months. If it is not charged after this period, its capacity will decrease.
