Your robot cannot stay outside over the Winter, it is really bad for the battery.  It also needs to be charged at least once per month.  We don't recommend leaving it on the charger. 

Charge the battery fully prior to bringing your robot indoors. Keep your base intact and use this cable to charge it. This avoids hassles in the Spring, such as docking issues due to not installing the base correctly.

If your robot has the Connect module with GPS and Geofence is enabled, make sure you turn off the robot with the switch and the PIN (when Geofence is enabled) or a deep discharge of the battery can occur which is detrimental to to the battery. Then charge the robot at least once per month. Turn the robot on and the charging session will get recorded in the robot's memory (required for the second year battery warranty). This will keep it in top condition.

Robot Models vs Winter Charging Cables

L15/L20/Quad: These models do not use a winter charging cable. The L15/L20 base tower snaps onto the platform. The Quad tower must be unscrewed. Remove the tower to bring it indoors for winter charging with the power supply that came with the robot.

L85: Choose the alligator style winter charger. Then connect smaller alligator test leads to the cable's alligator clips, being careful not to short the alligator clips.

4.0/4.36: Choose the port style winter charger.

When to Purchase the 2A Trickle Charger

If the robot's battery is larger than 5Ah, it is necessary to add the 2A Trickle Charger option to your order. This charger works with all robot models, but in most cases, it charges more slowly than the charger that came with the robot. Do not use a battery charger greater than 5A with the winter cable because it will melt the cable's plastic.

Re-charge the robot with the Winter Charger before setting it up outside and you are good to go!

Although it is not absolutely required, it is best to bring the base electronics inside. Models that have a base tower: some snap onto the base platform, others are installed with two screws. Remove the perimeter wires from the connectors, then remove the tower. Models that have an arch: remove the left panel, take out the perimeter wires, slide the transmitter off of its posts. When re-connecting in the spring, remember that "Back is Black", that is the wire from the back of the base goes to the black terminal, the wire from the front goes to the red terminal.
