What Are the Technical Specifications of the Panasonic CR-P2 Battery?
The CR-P2 provides 6 volts with a nominal capacity of 1,500mAh. Dimensions are 34.5mm x 19.5mm x 9.5mm, weighing 12g. It uses lithium manganese dioxide chemistry (Li-MnO2), ensuring stable voltage output. Operating temperatures range from -40°C to 60°C, and it meets IEC 60086-4, UL, and UN38.3 certifications. Shelf life extends up to a decade with minimal self-discharge (2% annually).
How Does the CR-P2 Compare to Other 6V Lithium Batteries?
Unlike alkaline 6V batteries, the CR-P2 offers higher energy density, lower self-discharge, and superior cold-weather performance. Competitors like Energizer L544 and Duracell 6V lack equivalent capacity (1,500mAh vs. 1,200mAh). Panasonic’s leak-proof design and 10-year shelf life outperform generic brands, making it optimal for medical devices and emergency equipment requiring dependable power.

What Devices Are Compatible with the CR-P2 Lithium Battery?
Common applications include blood glucose monitors, digital thermometers, Olympus/Pentax camera flashes, and industrial sensors. Refer to device manuals for voltage compatibility. Avoid using in non-6V electronics, as overvoltage risks damage. Panasonic recommends replacing batteries in pairs for multi-cell devices to prevent uneven discharge.
The CR-P2 is particularly suited for devices requiring consistent power over extended periods. For example, in emergency lighting systems, its low self-discharge rate ensures readiness even after years of storage. Medical professionals favor this battery for portable diagnostic tools due to its ability to maintain voltage stability during high-precision measurements. Below is a compatibility table for common devices:
| Device Category | Examples |
|---|---|
| Medical Equipment | Blood pressure monitors, pulse oximeters |
| Photography Gear | External flash units, light meters |
| Industrial Tools | Laser levels, gas detectors |
Why Choose Lithium Chemistry for the CR-P2 Battery?
Lithium manganese dioxide ensures lightweight construction, high energy density, and resistance to extreme temperatures. Unlike NiMH or alkaline, Li-MnO2 minimizes voltage drop during discharge, critical for precision instruments. The chemistry also eliminates mercury/cadmium, aligning with RoHS environmental standards.
Lithium batteries like the CR-P2 excel in scenarios where weight and performance are paramount. Their ability to operate in sub-zero temperatures makes them indispensable for Arctic research equipment, while the absence of memory effect allows partial discharges without capacity loss. Compared to silver-oxide alternatives, lithium chemistry provides a 20% longer runtime in continuous-use devices like security sensors. This electrochemical stability also reduces the risk of sudden failure in mission-critical applications.
How to Store and Dispose of the CR-P2 Safely?
Store CR-P2 batteries in cool, dry environments below 35°C. Avoid contact with metal objects to prevent short circuits. For disposal, follow local e-waste regulations—lithium batteries require recycling at certified centers. Never incinerate, as thermal runaway risks explosion. Panasonic provides prepaid recycling kits in select regions.
What Safety Features Does the CR-P2 Include?
Panasonic integrates a pressure-relief valve and anti-corrosion steel casing to prevent leaks. The battery is UL-certified for short-circuit and overcurrent protection. Internal separators inhibit dendrite formation, reducing rupture risks. Always inspect for damage before use and avoid mixing with other battery types.
“The CR-P2’s decade-long shelf life and robust temperature tolerance make it indispensable for medical and aerospace sectors. Its lithium chemistry balances energy density with safety—a rare combination in disposable batteries.” — Industrial Power Solutions Expert
Conclusion
The Panasonic CR-P2 lithium battery sets the benchmark for high-drain 6V applications, combining technical excellence with stringent safety protocols. Its specifications cater to industries where reliability is non-negotiable, backed by global certifications and environmental compliance.
FAQs
- Can the CR-P2 Be Recharged?
- No—it’s a primary (non-rechargeable) battery. Attempting to recharge may cause leakage or explosion.
- Is the CR-P2 Legal for Air Travel?
- Yes, under IATA guidelines. Carry in original packaging and declare if exceeding 2g lithium content per battery.
- What’s the Difference Between CR-P2 and CR123A?
- CR123A is 3V, while CR-P2 is 6V. They’re not interchangeable. Using CR123A in a 6V device may result in underperformance.
