Common Usage
Because Zinc-Carbon batteries excel in low-drain or intermittent-use scenarios, they are most commonly used in:
- Timekeeping: Analog wall clocks and alarm clocks.
- Control: Television, AC, and audio system remote controls.
- Safety: Smoke alarms and carbon monoxide detectors (where low current is pulled over a long time).
- Simple Toys: Small electronic toys without heavy motors or bright lights.
- Basic Tools: Handheld calculators and transistor radios.
