X20 Console Manual
The best way to long-term store an X20 ready for use is switched
off and attached to a 13.8V mains adapter (optional extra) at
room temperature. This will continuously cycle the internal battery
between 8V and 10.8V. The charger will operate for twenty
minutes with the first 14.5 minutes at rapid charge followed by
7.5 minutes of pulsed top-up. The charger will switch on about
once every two weeks, but depends on the initial charge level.
This will keep the battery at about 40% charge.
After extended storage, and if the X20 console will not start
(battery LED is red), bring the X20 up to room temperature (above
10°C (45°F)) and connect to 13.8VDC mains adapter or connect to
tractor harness. Leave it switched off but connected, and notice
that the battery LED will start to flash green. This means that
rapid charge is in progress. The X20 console is usable after about
5 -10 minutes. This cycle will last for about 20 minutes if left. If
the battery is so discharged that the voltage is below 8V the battery
will trickle charge until the voltage rises above 8V and will then
rapid charge. This is a function of the battery chemistry, as are the
temperature limitations on charging.
Be aware that fast charge and pulse top-up only operates in the
range 0°C (32°F) to 50°C (122°F). At temperatures outside this
range the charging process is a trickle charge only.
TIP
Storing the X20 console in this way will give the battery
its longest possible life.
