Chemistry

Chemistry refers to the type of materials used to create the battery. 18650 batteries come in two main types: lithium-ion (Li-ion) and nickel-cadmium (Ni-Cd). Li-ion batteries have a higher energy density, which means they can store more energy for their weight, and they also have a longer lifespan. However, they can be more sensitive to temperature changes and have safety risks if not handled properly. Ni-Cd batteries are more robust and tolerate temperature fluctuations, but they have a lower energy density and a shorter lifespan compared to Li-ion batteries.

Charging Considerations

Before purchasing a 18650 battery, ensure that your device is compatible with the charging method required for the battery. There are three common methods: manual charging, automatic charging, and protected charging. Manual charging requires user intervention, while automatic charging can be dangerous if the battery is not designed to handle it. Protected charging includes built-in safety features that prevent overcharging and ensure the battery's longevity.

Multiple people pointed out in the beginning scene when energized TV man was teleporting into the base of the toilets, there seemed to be a figure in the background. some people speculate that this could be another teaser or hint for computer men.
I have no basis for this, but Here is some of the powers that would make sense or be a cool idea for a computer man
the ability to "hack" the toilets without needing to use hypnosis or any type of beam. They could simply hack and shut down the equipment, causing failure.
Maybe they would have some form of "telekinesis", where they can simply pick up knives and move them with their mind, or throw toilets around at will, maybe instead of hypnosis, they project a tractor beam from their screens which is used to move and manipulate objects around, kind of like a built in Gmod phys gun.
Maybe they also have the tech to 3d print weapons and gadgets quickly, building guns and vehicles faster than the other races.
A cool way for the computer men to communicate would be binary or hexadecimal code appearing on their screens. They could also communicate audibly by making dial up noises.
Possible computer man sighting
