Common Names for the 9V Battery

IEC and ANSI Designations:

  • IEC: 6LR61 (alkaline)
  • IEC: 6F22 (zinc-carbon)
  • ANSI: 1604A (alkaline)
  • ANSI: 1604D (zinc-carbon)

Common Names:

  • 9V battery
  • PP3 battery (original series name from the manufacturer Ever Ready)
  • E-block battery

Typical Chemistry Types:

  • Alkaline (most common consumer version)
  • Lithium (longer life, lighter)
  • Nickel-metal hydride (NiMH) (rechargeable)
  • Zinc-carbon (cheaper, shorter lifespan)

Common Uses:

  • Smoke detectors
  • Guitar pedals
  • Radios
  • Multimeters

Typical Discharge Current of a 9V Battery

1. Alkaline 9V Battery (e.g., Duracell, Energizer)

  • Continuous current: ~15–50 mA (milliamps)
  • Peak current: Up to 400–500 mA (for short bursts)
  • Capacity: ~500–600 mAh (at low drain)

2. Zinc-Carbon 9V Battery

  • Continuous current: ~5–15 mA
  • Peak current: ~100–200 mA
  • Capacity: ~400–500 mAh

3. Lithium 9V Battery

  • Continuous current: Up to 120–200 mA
  • Peak current: Often 500–1200 mA
  • Capacity: ~1000–1200 mAh

4. Rechargeable 9V Batteries

  • NiMH (Nickel-metal hydride):
    • Typical current: 50–100 mA continuous
    • Peak current: ~200–400 mA
    • Capacity: ~150–300 mAh

Notes:

  • Drawing high current continuously will reduce battery life quickly.
  • Actual current delivered depends on the internal resistance and load.
