GRACE EASY Manual
Connect the plug on the charging cable to the socket
on the battery.
Next, connect the charger to the mains with the
mains plug.
The LED ring on the battery socket briefly lights up red before switching to orange. When
properly connected, an acoustic signal will sound. The battery is charging.
After the battery has been fully charged, the charging will stop automatically. Disconnect the
charger from the mains and the battery from the charger. The battery is switched off
automatically.
It takes about 5 hours for the battery to fully charge. When charging is complete, the LED
ring will go from orange to green. Unplug the plug on the charger from the battery followed
by the mains plug from the socket.
Ideally, charge the battery at a room temperature of 20°C (68°F). Before
charging, give the battery enough time to reach this temperature itself.
Avoid fully charging the battery too frequently. The battery prefers to be
partially discharged. There is no memory effect in Lithium-ion batteries.
Quick discharges followed by charging can cause the charge indicator to no
longer correspond to the battery's charge state. For this reason, after
around 30 charges, fully discharge the battery and charge it up again
afterwards. This does the required calibration of charge indicator with
charge state.
All Lithium-ion batteries are subject to function-related wear. Normal use and
the ageing process causes the battery cells to oxidate. The battery loses capacity.
The typical life expectancy of a Lithium-ion battery is currently 2 to 3 years,
regardless of whether the battery is in use or not.
