I can open mine with my left pinky finger. Even my cat (not mine really, stray cat) can push fold it

Sliding auto gate will be heavy, mostly because the gate itself is already heavy..
But for swing or folded gate, it just like opening a normal gate without the autogate (when autogate is disengaged)..

I removed my battery long ago,,,,,so far luckily no power failure.

Need to change within 2 years or remove the battery if dont want to use it. The battery is arround RM50-60. Can plug n play.

If you can open the gate by hand during power fail, I guess can save the battery cost.

Arm type autogate cannot be push because it use something like worm gear, it basically will lock the entire arm if no movement on motor, hence for these type of autogate have to remove the lock on the edge to remove the entire arm and push the gate.

You will notice arm have no locking solenoid like the old type (underneath) or DC motor, this because worm gear basically are very strong.

Bought the new battery for RM40, dunno what brand...ciplak one.
But at least can replace my 4 years old battery which the terminals all corroded with sulfur already.

40, that more like China brand.

Auto gate ,if power fails cannot use force to open the gate.Only way is remove the lock screw and open the gate or use battery power.
