Checking Battery Charge Status
After a HeartMate Battery is charged, it should be ready for use. After the Battery has finished
charging, use the on-battery Power Gauge to confirm that the battery is fully charged (
Figure
3.60 ).
Figure 3.60 Battery Symbol on the Battery (On-Battery Power Gauge)
The on-battery power gauge on a HeartMate battery uses five green bars to show available
battery power (
Figure 3.61 ). Each bar represents approximately 20% of available power.
When a battery is fully charged, all five bars light up when the Power Gauge button is pressed.
This indicates that the battery is 80–100% charged. Fewer bars illuminate as power is depleted.
When battery power drops below 10%, only one green blinking bar comes on.
