When the battery charge is complete, the “INTERNAL BAT“ indicator turns off.
Although it is not necessary to start the ventilator to charge the battery, charging the battery during
operation will increase the time required to fully charge the internal battery.
When recharging a depleted internal battery, it may be necessary to leave the ventilator on charge for
about four (4) hours if the ventilator is on standby and about 10 hours if ventilation is operating.
6.5 Storing the Battery

WARNING
Even if the “INTERNAL BAT“ indicator is off, charge of the battery may sometimes be incomplete regardless
of charge time when the ambient temperature is above 104 °F (40 °C). This is due to the characteristics of
the battery’s internal heat safety device.
WARNING
Using the ventilator on an external 12 –30 VDC power source does not enable charging of its internal
battery.
