An empty Battery must charge up to 5 hours to reach full
capacity.
2 Battery run time: Approximately 45 minutes of continuous
operation at zero vacuum level (free flow), fully recharged.
3 Always fully charge Battery - before and after each use.
To prolong Battery lifetime it is recommended to place the
Battery on continuous charge. It will not harm the unit.
If continuous charging is not possible, charge Battery for
minimum 24 hours once a month. Completely discharging the
Battery will shorten its useful life.
When stored unused for > 3 months
• Fully charge Battery before storing
• Recharge every 3-6 months
Battery Test
When in operational use, the Battery should be tested every
6-12 months.
1 Start the test with a fully charged Battery.
2 Set Max Vacuum level.
3 Let the unit run for 20 minutes (free flow).
4 Block the Patient Tube.
5 If Vacuum level fails to reach 550 mmHg the Battery
should be replaced.
