Battery is noticeably average.

In a way, he is very simple yet complex. His energy being based off his current charge is simple on paper, yet it acts as the most complex trait in his physiology. One lasting charge is all it takes for him to become restless (in either a good or a bad way). 100% or 1%, this obviously comes with its pros and its cons, one of which he tries to be very particular about: being on the same tempo as others, even if he's not so obvious about it.

Personality-wise... compared to everyone else, he's more of a blank slate. He's open-minded and independent, yet his views on things are easily influenced. He doesn't really do a lot by himself, so he's usually seen doing activities with his friends because he doesn't posess a lot of hobbies or interests of his own... He's always eager to see what others are up to—that is, if he has the energy for it!

While Battery is quite open-minded, he has a very homogenous view on all of his friends. Even though he hangs around Word Tile and Strawberry the most, Battery sees all his friends in the same light, despite having slightly varying opinions. It's hard for a guy like him to pick sides, and sometimes he'll find himself in the middle of two opposing forces. While some of his friends try to take advantage of this, he never lets himself get swept under the rug. His one notable trait does not speak for him alone, as his own independence does that in volumes well enough!

Battery is an indigo type-C battery, modified to be unlike any other conventional type-C battery. Because of this modification, his exact composition, voltage, and storage capacity all remain nebulous. They could be around anything in-line with a normal, conventional type-C battery, but never exact. In any situation that would call for a type-C battery, however, he will still function as such.

Even though he is strictly a battery, he functions as an electricity receptacle. This means he can utilize the current stored within him for external usage. In short: he can use electricity. Because of this (and the fact he is a battery), he is effectively immune to electricity. Whether it be to power, charge, or shock something, Battery can use his own energy to do so—which can also go vice versa, if need be.

Primarily, Battery is charged from the bottom cathode. He can receive energy from the top cathode, though it is far slower that way. Finding the right voltage will vary. While it isn't too much of a dangerous game to play, it is possible to short-circuit him if done incorrectly. How much energy he has stored within himself is indicated by green lights near his cathodes, shifting from a bright green (>90%) to a warm yellow (~50%) to a dim red (<10%).
