Panasonic CR123A Lithium Battery, 3 V 1550 mAh Button-Top Primary Cell for High-Drain Devices

The Panasonic CR123A is a robust primary (non-rechargeable) lithium‑manganese dioxide (Li‑MnO₂) battery designed for high‑drain electronics. Delivering a nominal 3 V output with 1550 mAh capacity (under 100 Ω load at 20 °C), it supports high current bursts and exhibits stable voltage during discharge. Compact and lightweight (≈17 g), it features a durable construction and a broad operating temperature range of –40 °C to +70 °C, making it ideal for industrial, security, medical, and imaging applications.

Key Features:

• High-energy capacity: 1550 mAh at standard load (100 Ω at 20 °C).
• Nominal voltage: Consistent 3 V output throughout discharge.
• Compact and lightweight: Dimensions – diameter 17.0 mm × height 34.5 mm; weight ~17 g.
• Wide operating range: –40 °C to +70 °C ensures reliability in extreme conditions.
• High pulse current capability: Supports up to 900 mA pulses (3 sec on, 27 sec off) with long cycle endurance.
• Stable discharge with internal safety: Includes PTC device; low impedance (~1 Ω), stable voltage.
