1. Replace the charging station circuit board, or the
baseplate (including the N and F wires). Refer to
To
replace the circuit board in the charging station on
page 31
and

station and the charging station cap on page 30
.
8.3.4 Red solid light
A solid red light is probably a fault in the circuit board, or
an incorrect power supply in the charging station.
1. Check the power supply.
2. Replace the charging station circuit board. Refer to
To replace the circuit board in the charging station
on page 31
.
8.4 Battery test
If the product’s battery starts to perform poorly, the
product mows for shorter time periods. The product can
also stop and show the
Low battery
message.
Note: A battery test can be run on the workbench with
Autocheck, but the most reliable test result is achieved
when the product is run in an installation.
8.4.1 To do a battery test
1. Fully charge the battery.
2. Set the cutting height to maximum.
Note: The product must have a low level of cutting
resistance during the battery test.
3. Let the product mow in secondary area operation
mode until the battery is empty.
4. When the battery is empty the product stops. The
result of the battery test is then saved automatically
and can be found in Autocheck or in the
Tools
menu
.
8.4.2 To evaluate the battery test
A new battery has a total capacity of about 5.0 Ah but is
charged to a maximum of 4.0 Ah. The test results from a
battery test on a new battery are normally around 3.8 -
4.0 Ah.
As the battery ages the battery capacity decreases. If
the battery capacity displayed is approximately half of its
initial value or lower, it is possible that the battery is poor
and needs to be replaced. The assessment should be
based on the most recently conducted test as the first
test can show an incorrect value. It is therefore more
practical to perform a battery test in connection with the
product’s normal operation or in connection with it
having recently been in operation.
Note: The values are approximate and vary between
different products and batteries.
Note: If the product has not been in operation for more
than two months, at least two and preferably three
battery tests must be carried out.
