Just a tip… so its raining, windy and cold - the last thing you want to do is go out and operate your gate manualy, yet, thats how the Peter Principle goes - raincoat, boots and tools… the keyboard LCD screen shows a reboot every time I do the settings and the motor barely kicks in - a faint hope… the battery is at 13.5V so lets see, it could be the PCB? After hours, even using another battery, no joy; so its eiter the PCB or the motor.
Yet as I used another, new, 12V 9Ah battery [after 2 days] everythingh started working - bottom line, use a strong, fully charged 12V battery, not 7Ah but 9 if possible!
Now for a well deserved cuppa…

Have these gate operators been taken over by the Nice Group?
I can’t establish who’s who between E.T. Centurion and Nice…

Those gate motors don’t have a power supply strong enough to run the motor without assistance from the battery. A weak 12V battery absolutely will stop the gate from running even if the power supply is good.
In my experience, the 9Ah battery has thicker and sometimes even wider terminals, so you might struggle to get the terminals to fit on the battery, even if physically it is the same size. For that reason, I replace with a 7Ah. The larger capacity costs more and has an insignificant effect on how long the thing is going to last.

hi @plonkster , yes, the terminals were wider - so I had a choice, attach wider plugs on the wire terminals or trim the battery terminals - I went for the latter… and voiding the warranty in the process; but what did they say back on the border, ‘Whiskey is a bargain even at R50 per bottle’ - rather that than kneeling down in the wet and performing that operation in the confined space with my stiff hands

I run my Centurion gate motor off a 100 Ah battery which is in a cabinet around 6m away from it. Come to think of it I can’t even remmember how I connected the 16mm cable I used, to the small battery terminals which is on the motor, but it works and there is almost no voltage drop.
Replace the standard 7 Ah with a lithium battery, at my previous house I had a 7 Ah lithium in my Centurion motor for around 3 years until I sold the place, it never missed a beat through rain and shine, plus it was at the hight of load shedding.
hi @JN.V , that’s the solution; yet I am quite impressed as the battery that pegged was an ordinary lead-acid 7Ah and lasted for about eight years with an average of 6-7 open/closed cycles per day [about 19k cycles], I can hardly believe it; caveat being my memory…
Maybe but only if no load shedding. If they get seriously discharged they don’t last :
yip @Richard_Mackay , loadshedding [in SA it’s lodeshedding ala the old PC game Lode Runner] would have ruined it as it did thousands but thanks to a PV system there was a constant charge
