Energizer 2CR5 Battery (6V) — What to Know Before You Buy

The Energizer 2CR5 is a primary (single‑use) lithium battery designed for high‑drain bursts such as camera shutters and flash metering, while maintaining long standby life. Choose it when your device specifically calls for 2CR5/CR‑P2.

At a Glance

When to Choose (and When to Avoid)

• Use if: Your device lists 2CR5/CR‑P2; you need reliable power after long storage (emergency kits, infrequent use); you operate in very cold or hot environments.
• Avoid if: Your device accepts rechargeable packs and you shoot daily (a rechargeable solution may be more economical); your device uses AA, CR123A, or CR2 cells (not cross‑compatible); you need USB/plug‑in rechargeability.

Typical Uses

• Film and early digital SLRs/point‑and‑shoots: Canon, Nikon, Pentax, Minolta models that specify 2CR5/CR‑P2.
• Rangefinders and meters: Golf/optical rangefinders and light meters designed for 2CR5.
• Security sensors and specialty electronics: Devices requiring a compact 6 V lithium pack.

Runtime Expectations

Actual life varies by device and settings. As rough guidance for film cameras:

• Light to moderate use, minimal flash: roughly 10–20 rolls (36 exposures each).
• Heavy flash use or cold weather: as low as 2–8 rolls.

For non‑camera devices, refer to the manufacturer’s guidance, as duty cycles differ widely.

Compatibility and Equivalents

• Fits only: Devices that specify 2CR5, CR‑P2, DL245, EL2CR5, or 245.
• Not a replacement for: Two CR123A or two CR2 cells (different shape/contacts), or AA batteries.
• Alternatives: If unavailable, consider branded equivalents such as Duracell DL245 or Panasonic CR‑P2, provided your device lists them.

Storage and Handling

• Store cool, dry, and in original packaging; avoid direct sun and humidity.
• Do not mix old and new batteries in the same device.
• Remove the battery if the device will sit unused for a month or more.
• Avoid carrying loose batteries with metal objects to prevent short circuits.

Safety and Disposal

• Do not recharge, disassemble, crush, or incinerate.
• If a battery is hot, leaking, or swollen, handle with care and recycle promptly.
• Recycle at approved battery collection points; do not dispose of in household trash.
