2. Allow the robotic lawnmower to mow in
manual operating mode until the battery
is completely at. The mower should have
a low level of cutting resistance during
the battery test. The cutting height should
therefore be set to maximum.
3. When the battery has run down the mower
stops. The result of the battery test is then
saved automatically and can be read in
Autocheck EXP or Tools - History, total -
Battery capacity in the mower's display.
In cases where a battery test cannot be performed on
an installation, the test can be performed directly on
the work bench via Autocheck EXP. The test is per-
formed as above, except the mower's drive wheel and
blade disc rotate freely during the test. Since resist-
ance to the drive wheel and blade disc is in principle
non-existent, discharging the battery may take sev-
eral hours Note that the most reliable test results can
be achieved when the mower is run in an installation.
6.6.2 Evaluating the battery test
The 4 most recent battery tests are saved in the
mower. Read the test result from Autocheck EXP or
Tools - History, total - Battery capacity in the mower.
A new battery has a total capacity of about 3,200 mAh
but is charged to a maximum of 2,600 mAh. The test
results from a battery test on a new battery are thus
normally around 2,500 to 2,600 mAh.
As the battery ages the battery capacity decreases.
If the battery capacity displayed is approximately
1500 mAh or lower, it is possible that the battery is
dead and needs to be replaced. Note that the values
are approximate and vary between different mow-
ers and assume that the measuring is done as de-
scribed. NB! If the mower has not been in operation
for more than 2 months when the test is performed,
for example if the mower has been put in for a win-
ter service, at least 2 and preferably 3 battery tests
should be carried out. The assessment should be
based on the most recently conducted test as the
rst test can show an incorrect value. It is conse-
quently more practical to perform a battery test in
connection with the mower’s normal operation or in
connection with it having recently been in operation.
When replacing the battery the charging cycle coun-
ter should be reset. This is done in Tools - Reset
charging cycle counter in Autocheck EXP. This re-
sets the value for Chargings OK, which is a measure
of how old the battery is, both in the main counter
and the trip counter. A battery can normally take ap-
proximately 3,000-4,000 charges.
