Maintenance-free sealed lead-acid batteries used in the system do not require the addition of water or electrolyte. These batteries are charged
and maintained in a fully charged state by the main power supply’s charger during normal system operation. A discharged battery typically
reaches the voltage of 27.6 VDC within 48 hours;. Sealed lead-acid batteries must be replaced within at most 5 years from their date of man-
ufacture. Minimal replacement battery capacity appears on the control panel marking label. Immediately replace a leaking or damaged bat-
tery. Replacement batteries are available from the manufacturer.
