The battery would have to supply this current in full or 12 X 7.5 = 90W for a useful 30W output. 2/3 of your power would be wasted as heat. Whether using a buck converter or a linear regulator the power required from the battery will be roughly proportional to the load.
Whether a battery is a constant voltage source or current source
A battery is considered to be a voltage source because the galvanic activity they use to store and deliver energy has a fixed voltage across it. However, a battery is not an ideal voltage source. All real sources have some built in resistance.

Battery charger, is it a current source or a current-limited
Real world "current sources" are either voltage sources that use feedback to maintain a current limit, or have a non-linear curve that include a region with a somewhat constant current. (OK, yes, there is an ideal current source in the real world: a radioactive particle that emits a constant stream of beta particles.)
Is a Battery a Constant Source of Voltage? Exploring Voltage vs
Current delivery: Current sources provide a constant amount of current. For example, an ideal current source will supply 1 ampere of current irrespective of how much resistance is present in the circuit. In contrast, a battery supplies voltage, and the current output depends on the connected load.

6 FAQs about [Is the battery a current source ]
What type of current is produced by a battery?
The current produced by a battery can be either AC or DC depending on the power source. In the case of a battery discharging, the current is DC. A direct current flows in one direction, maintaining a constant polarity. This is different from alternating current, which constantly changes direction.
Is a battery a DC or AC source?
A battery can be either a direct current (DC) or alternating current (AC) source, depending on how it operates. The current flow in a battery is always direct, meaning it flows in one direction. This is in contrast to AC, where the current alternates between positive and negative directions.
Can a battery be a direct source of DC current?
A battery can be a direct source of DC current. It operates by converting stored chemical energy into electrical power. However, a battery can also be charged by an AC current. AC supply is used to supply current to the battery in alternating cycles, which is then converted into DC current by the battery.
Can a battery be used as a power source?
A battery, which is a DC power source, can be used to convert DC current into AC current, making it a valuable source of AC power. This innovation has paved the way for portable AC power supplies, enabling us to use AC-powered devices even in remote locations.
Will battery technology revolutionize the way we think about power sources?
In the future, advancements in battery technology will revolutionize the way we think about power sources. Currently, most of the technology we use operates on either AC (alternating current) or DC (direct current) power. AC current is what we typically find in the power supply to our homes, while DC current is what batteries produce.
Why is a battery considered a voltage source?
As the chemistry shifts with discharge (or charge) the no load voltage changes slightly and the internal resistance changes as well. A battery is considered to be a voltage source because the galvanic activity they use to store and deliver energy has a fixed voltage across it. However, a battery is not an ideal voltage source.
