The little wall wart is pulling 36w when charging. Multiply by 8hrs = 288 watts out of your battle borns give or take. The input specs are irrelevant just look at the output.
Watts used for a lead acid battery scooter charger?

No, it means that battery consumes 240Wh of energy.
Over 8 hours that would be 30watts per hour
Over 6 hours that would be 40 watts per hour.
But more likely, the battery is registering empty after 120Ah of use... so the battery only pulls 15watts per hour to charge.
A kilowatt will tell the true usage, but my guess is itll be pulling a 50%SOC 120Wh so around 20 watts per hour...
Let us know what your meter reports.
To complicate this, the charger likely draws 80 watts for the first few hours, then 10 or so watts until full.
This depends on the controller profile.
It is why a kilowat meter is so jandy.

Here is the battery: https://www.amazon.com/Universal-Po...=2025&creative=165953&creativeASIN=B00BUCUPV6
If you change to the lithium iron replacements, you get lower weight, and longer recharge life.

AND..... charging the batteries from the 24V wall charger will have different charge rates, times and overall Wh than if you tie the batteries directly to the solar DC/DC Renogy. Not dramatically, but different.

They don't sell the lithium batteries for my scooter, only lead acid. Can I convert my scooter to lithium just by finding the same sized ones?
I don’t see why not. You might post this question in the general forum and see if any scooter experts are out there to disagree.
The batteries you linked to are standard UPS batteries. I have a couple. They are very common. I would hope they have those in lithium ion versions too.
Yay! They have a LiFePo version: https://www.amazon.com/Discharge-Li...ds=UPS+battery+lithium&qid=1574348605&sr=8-25
Lithium ion version: https://www.amazon.com/Lithium-Flas...ds=UPS+battery+lithium&qid=1574348605&sr=8-34
Double check the physical dimensions on your battery you currently have against the batteries I linked to, to make sure the physical size is the same or a bit smaller.
But you may not be able to use the same schooter charger for Li-Ion batteries as the upper cutoff voltages are different.

Thanks for the links. I also asked on Amazon and someone just said yes, but be careful and something about his buddy's scooter having a thermal effect after changing the controller and almost catching fire!
I would like to know what that guy did!
LIFEPO4 just dont catch fire... it's why will recommends them.

Here is his answer: "You can, just make sure your discharge rate on the Li-ion isn't below the draw rate at full throttle on the scooter. My buddy got a different controller, and the discharge rate was less than the draw and one of the battery's went into thermal and almost caught fire. "
Almost caught fire...
Nope...
almost burst, or almost melted the wiring, or bulged and vented smoke...
But LiFePO4 doesn’t catch fire... unless you put it in a fire.
Maybe some wires on the scooter smoked a bunch. I had that happen on a tiny desktop vacuum using only a single AA battery. How the darn thing drew enough current to set the wire coating smoking is beyond me. But it was a neat trick! I can't even do the same trick by connecting 2 wires directly to an AA battery.
