Since you have a battery and it is a sliding gate, I will assume you have a Roboslide model by Elite. The battery has to be charged in order for the gate to work. The charging comes from a transformer or a solar panel. Check to make sure these have power coming out of them. Most gate operators use a transformer and if the two wires providing the voltage touch each other, it will blow the transformer. If you have a volt ohm meter you can check this. You might need to use the AC setting as well as the DC since some are 18 volt DC and others are 25 volt DC. You can do the same for a solar panel but only use the DC setting.

If this is not your issue, then make sure it is your battery draining and not something binding in either the motor or the gate. Finally, it could be the motor going out. Simply hook the charged up battery directly to the motor to check it. It should respond strongly. Reverse the leads to make the motor go the other way.

Good luck.

There are several possible causes, but the first to check is the limit switches. When the gate opens, it is supposed to trip a limit switch that tells the mechanism that the gate is fully open. If the switch is not tripped, it will not respond properly to a command to close. It may think the gate is running into an obstruction and then just shuts down.

The opener may have been mounted improperly or may have slipped from it's original mounting location. You may not be able to make an adjustment because the arm is already fully extended.
You may have to re-position the gate opener.
Fixya doesn't do repairs. Posting a question here is like calling the public library for an answer that they can look up.

Need more information.
Firstly, engage the manual release inside your motor and then operate gate by hand. Pay attention to any spots that are hard to push, this would indicate some sort of mechanical obstruction causing the motor to stop. Try remove obstruction.
Secondly, measure the voltage on your battery while trying to operate the gate. If your battery drops below 11.5V the control board will shut down. If so, replace battery.

If you disengage the motor does the gate slide easily? if not that could be the problem, most gate control boards have a sensor that detects the current drawn by the motor, if the gate hits an obstruction or is jammed the motor draws more current and the sensor stops the gate moving. It could also be a problem with the safety sensor, to check this locate the safety sensor input on the control panel and bridge the 2 contacts if the gate then works the safety sensor is the problem.

the auto close has been set or the motor has been set up in reverse and it is auto reverseing,make sure the gate is opening up all the way, if it is not just help it along and see what happens.

if the motor cant rotate the shaft by itself, its likely a burned coil in the motor, but if the motor is running but not moving the gate then its a broken gear
