What type of batteries are known for being non-rechargeable and providing direct current?

Primary cells are known for being non-rechargeable batteries that provide direct current. These batteries are typically designed for single use, meaning that once they have discharged their stored energy, they cannot be recharged and reused. Common examples of primary cells include alkaline batteries and lithium batteries, which are widely used in everyday applications like remote controls, flashlights, and portable electronic devices.

In contrast, secondary cells are rechargeable batteries that can be used multiple times by reintroducing energy into them. Rechargeable batteries specifically refer to a class that can regain their charge through an external power source, which further distinguishes them from primary cells. High-capacity cells, while they might refer to batteries with larger energy storage, do not specifically address the non-rechargeable aspect that defines primary cells.

The characteristic of providing direct current is common in both primary and secondary cells, but it is the non-rechargeable nature of primary cells that is a defining trait highlighting their role in various applications where recharging is impractical or unwanted.
