Esser 018002 12 V 2.3 Ah Backup Power Battery

This battery offering 2.3 Ah capacity at 12 V is one step above the 1.2 Ah model. When mains power fails, it stores the energy needed for the control panel and connected devices to continue operating. It is widely used in small-scale installations, auxiliary panels, and repeater units. An increase of one capacity step means longer backup duration in the same cabinet size.
