CR Batteries – The Silent Power Behind Critical Devices

CR Batteries – The Silent Power Behind Critical Devices

Subheadline: 10-Year Shelf Life. Pulse-Proof Voltage. Zero Leakage.

In the world of compact power, there is no room for failure. Your pacemaker, your car’s TPMS sensor, your industrial memory backup—these systems don’t warn you before they fail. They simply stop.

That is why engineers, device manufacturers, and technicians trust CR Batteries.

Built on a foundation of lithium manganese dioxide (Li/MnO₂) chemistry, CR batteries deliver the highest energy density per cubic centimeter in the coin cell category. But not all coin cells are equal. Here is what separates CR from the rest.

1. Legendary Shelf Life – 10 Years Ready

Standard alkaline or silver oxide cells self-discharge at up to 5% per year. CR batteries utilize a passivated lithium anode and a non-aqueous electrolyte system that reduces annual self-discharge to less than 1% per year.

• 10-year shelf life at room temperature (20°C)

• 85% rated capacity remains after a decade

• Ready to use straight from storage – no activation required

For emergency equipment, remote sensors, and long-term installations, this means install once and forget for a decade.

2. Stable 3V Platform – Flat Until the End

Many batteries show a steady voltage decline as they drain. CR batteries deliver a flat discharge curve – staying near 3.0V for over 90% of their useful life.

This stability is critical for:

• Medical devices (glucometers, thermometers, pacemaker programmers)

• Automotive key fobs (consistent RF transmission)

• Motherboard BIOS memory (no data loss during voltage dips)

3. Superior Leakage Protection – The CR Seal

Leaking batteries destroy devices. CR Batteries incorporate a triple-laser-welded seal and a stainless steel can that withstands internal pressure buildup. Combined with a PTFE gasket, the result is:

• Zero electrolyte creep under normal use

• Pressure vent that activates safely only under extreme abuse

• Passed ISO 12826 leak integrity tests

Result: No corrosion, no white crust, no ruined devices.

4. Built for Real-World Extremes

While standard coin cells struggle in cold weather or high humidity, CR batteries are engineered for environmental resilience:

• Low-temperature performance: Delivers 80% of nominal capacity at -20°C (competitors often drop below 50%)

• Humidity resistance: Sealed to withstand 90% RH for extended periods

• Vibration tolerance: Tested to IEC 60068-2-6 for automotive use

This makes CR Batteries the choice for outdoor TPMS sensors, parking meters, and marine beacons.

5. Green Chemistry – Mercury & Cadmium Free

CR Batteries contain zero added mercury, cadmium, or lead. They are fully compliant with:

• EU Battery Directive 2006/66/EC

• RoHS 3 (2015/863)

• UN38.3 for safe transport

While all coin cells should be recycled, CR’s clean chemistry reduces environmental risk during collection and processing.
