Energizer 223 Batteries

Energizer 223 (CR‑P2) Lithium Battery — What It Is

The Energizer 223, commonly labeled CR‑P2 or EL223AP, is a primary (non‑rechargeable) 6‑volt lithium manganese dioxide photo battery. It is designed for pulse‑heavy loads in cameras, rangefinders, and select motion or security sensors where fast response and stable voltage are critical.

Compatibility at a Glance

• Replaces/also known as: CR‑P2, CRP2, 223, 223A, DL223A (Duracell), EL223AP (Energizer), RL223A.
• Not the same as: 2CR5 (DL245), 4LR44/476A, or two separate CR123A cells unless a device‑approved adapter is used.
• Fit check: Look for “CR‑P2/223” on your device, battery door, or manual. The 223 has a rectangular body with two top contacts.

When to Choose It (and When to Avoid It)

• Choose if your device explicitly specifies 223/CR‑P2 and you need reliable performance across cold or hot conditions.
• Avoid if your device calls for a 2CR5 or 4LR44—these are different shapes/chemistries and will not fit correctly.
• Avoid rechargeable “RCR‑P2” substitutes unless your device manufacturer approves them (higher voltage can damage electronics).

Key Benefits

• Stable 6 V output for high‑drain photo equipment and sensing devices.
• Long shelf life (up to 10 years when stored properly) for emergency spares.
• Wide operating range: approximately −40°F to 140°F (−40°C to 60°C).
• Leak‑resistant construction to protect sensitive electronics.
• Lightweight vs. alkaline alternatives of similar voltage.

Typical Uses

• Film and digital cameras that list CR‑P2/223.
• Golf/hunting rangefinders.
• Motion detectors and select wireless alarm sensors.
• Specialty meters and instrumentation that require a compact 6 V lithium pack.

Technical Specs

Runtime Planning (Simple Estimate)

For rough planning, runtime (hours) ≈ capacity (mAh) ÷ device draw (mA). Example: a device averaging 100 mA could see around 15 hours. Cameras and sensors draw in pulses, so real‑world life often spans weeks to months of intermittent use.

Pack Sizes and Buying Advice

• Single pack: Replace one device as needed.
• 2‑pack: Keep a spare for field work or travel.
• Multi/bulk packs: Cost‑effective for teams, security fleets, or frequent shooters.

Installation Tips

• Match polarity and orientation; the two top contacts align with marked terminals.
• Do not mix old and new batteries. Replace as a set (one 223 per device).
• Clean contacts with a dry lint‑free cloth if you see residue.

Safety and Care

• Non‑rechargeable—never attempt to recharge.
• Avoid short‑circuiting the terminals (store in original packaging or a case).
• Store cool and dry; do not freeze or expose to direct heat.
• Recycle or dispose per local regulations for lithium primary batteries.
• Keep out of reach of children and pets.

Alternatives and Cross‑Shopping

• Other brands (e.g., Panasonic, Duracell) also offer CR‑P2/223 batteries; match the CR‑P2 designation.
• Adapters using two CR123A cells may work only if designed for your device; check manufacturer guidance.
• Rechargeable RCR‑P2 solutions provide different voltage profiles—use only if explicitly approved by the device maker.

FAQ

How long will a 223 battery last in a camera?

It depends on shooting style, flash use, and temperature. Many users see weeks to months of intermittent use; continuous high‑drain operation can deplete a cell in hours. Use the capacity ÷ load estimate to plan spares.

Is 223 the same as CR‑P2?

Yes. 223, CR‑P2, CRP2, EL223AP, and DL223A refer to the same form factor and 6 V chemistry.

Can I substitute a 2CR5 for a 223?

No. Both are 6 V lithium packs but the shapes and contacts differ. Use only the type specified by your device.

Should I choose rechargeable RCR‑P2?

Only if your device manual lists it as supported. Rechargeable versions often have higher voltage and different discharge behavior that can damage equipment not designed for them.

How should I store spare 223 batteries?

Keep them in their original packaging in a cool, dry place at room temperature. Avoid metal objects that could short the terminals.
