Panasonic 2CR5 Batteries

Panasonic 2CR5 Battery (6V) — What It Is

Panasonic 2CR5 is a primary (non-rechargeable) lithium battery designed for devices that need a compact, stable 6V supply. It is commonly specified for film and early digital cameras, external flashes, rangefinders, and selected security sensors. If your device calls for 2CR5 (also listed as EL2CR5, DL245, or 5032LC), this is the correct form factor.

Shelf Life	Up to 10 years when stored properly
Operating Temp.	Typically −4 to 140°F (−20 to 60°C). Check the Panasonic datasheet for exact limits.
Rechargeable	No (do not attempt to recharge)

When to Choose This Battery

• Use if your camera, flash, or sensor explicitly specifies 2CR5/EL2CR5/DL245/5032LC.
• Choose for intermittent-use gear (film cameras, seasonal security devices) where a long shelf life is valuable.
• Avoid if your device requires a different format (e.g., CR123A, CR2, AA) or a rechargeable power source.

Compatibility and Cross-Reference

Common equivalents include: 2CR5, EL2CR5 (Energizer), DL245 (Duracell), 5032LC. Some devices list only one of these codes—any should indicate the same physical and electrical format. Always confirm with your device manual.

Performance and Runtime (Real-World Guidance)

• High-drain bursts (camera flash recycling) benefit from stable 6V output versus alkaline options.
• Approximate runtime example: at a steady 1W load, theoretical runtime is ~6–7 hours (1400 mAh at ~0.17 A). In practice, expect less (3–5 hours) due to pulse loads, temperature, and device cutoffs.
• Cold weather reduces capacity; keep a spare warm in a pocket for outdoor shoots.

Storage and Handling

• Store cool, dry, and out of direct sun; keep in original packaging to prevent short circuits.
• Do not mix old and new batteries in the same device.
• Non-rechargeable: never attempt to recharge or disassemble.
• Recycle at approved battery drop-off locations; do not dispose of in fire.

Alternatives and Notes

• Two CR123A cells are not a drop-in substitute unless your device explicitly allows it; shape and contacts differ.
• Rechargeable packs labeled as 2CR5 exist but may have different voltages and protection circuits. Use only if the device manufacturer approves them.

Buying Tips

• Verify the code on your device or manual: 2CR5/EL2CR5/DL245/5032LC.
• Purchase from reputable sellers to avoid counterfeit cells.
• For frequent shooters or multi-device setups, multi-packs can reduce cost per unit.

FAQ

Is 2CR5 the same as EL2CR5, DL245, or 5032LC?

Yes—these are common cross-reference codes for the same 6V lithium form factor. Check packaging for any device-specific notes.

Can I recharge a Panasonic 2CR5?

No. This is a primary lithium battery. Attempting to recharge can cause leakage, rupture, or fire.

Will two CR123A cells work instead?

Not usually. Even though two CR123A cells provide 6V, the mechanical fit and contact layout differ. Use only if your device manual explicitly supports it.

How should I store spares?

Keep unopened in a cool, dry place around 50–77°F (10–25°C). Avoid high heat and humidity. Proper storage supports up to a 10‑year shelf life.

What temperatures can it handle?

Typical operating range is −20 to 60°C (−4 to 140°F), with reduced performance near the extremes. Always check the latest Panasonic datasheet for your exact cell.
