2.4.5 Sealed lead acid
battery
A sealed lead acid battery supplies battery backup for the Aestiva 7900
Ventilator. The Aestiva 7900 Ventilator is not a portable unit. Batteries for the
ventilator are used as back up power in case of a power failure. Thus the
battery is in a float charge state most of the time. Batteries meet the
following:
• Capacity to operate unit for 30 minutes.
• Long float charge life.
• Battery pack is internally fused - in line replaceable.
• Battery terminals and connecting wires are protected against short circuits.
