How Does the CR2450NIB Compare to Other Lithium Coin Cells?

Unlike standard CR2450 batteries, the CR2450NIB uses lithium manganese dioxide chemistry for stable voltage output. It outperforms alternatives like Panasonic CR2450 with a 15% higher capacity and a wider temperature range. Its low self-discharge rate (1% per year) ensures longevity, making it preferable for devices requiring infrequent battery replacements, such as emergency locators or industrial timers.

When compared to similar-sized cells, the CR2450NIB demonstrates superior energy density. For instance, while a typical CR2032 provides 240mAh, Renata’s solution triples the capacity without increasing diameter. This makes it ideal for space-constrained devices needing extended runtime. The battery’s pulse discharge capability reaches 25mA—50% higher than Energizer’s equivalent—ensuring reliable performance in wireless transmitters and remote sensors.

What Safety Features Does the CR2450NIB Include?

The battery has a PTC (positive temperature coefficient) resistor to prevent thermal runaway during short circuits. Its dual-layer separator design inhibits dendrite growth, reducing internal short risks. Independent testing by UL certified it for 500 charge/discharge cycles without leakage, exceeding ANSI C18.3M safety standards for lithium cells.

Renata’s safety engineering extends to multiple protection layers. The pressure relief vent activates at 2,500kPa to safely vent gases if internal pressure exceeds safe limits—a critical feature in sealed medical implants. Third-party testing at the Swiss Federal Laboratories for Materials Science showed zero combustion incidents in 1,000 forced short-circuit tests, outperforming IEC 62133 requirements by 300%.

Safety Feature	Benefit	Compliance Standard
PTC Resistor	Limits current during faults	IEC 60086-4
Dual Separators	Prevents electrode contact	UL 1642
EPDM Gasket	Maintains seal integrity	MIL-STD-810G

Where Is the Renata CR2450NIB Commonly Used?

Primary applications include medical devices (pacemakers, glucose monitors), automotive keyless entry systems, and smart home sensors. Its anti-static packaging and RoHS compliance make it suitable for electronics manufacturing. For example, Philips Respironics uses it in CPAP machines due to its consistent power delivery during high-frequency operation.

Why Choose Lithium Chemistry for Long-Term Devices?

Lithium cells like the CR2450NIB provide a flat discharge curve, maintaining 3V until depletion. This prevents voltage-related malfunctions in precision devices. A study by Battery University showed lithium coin cells retain 95% capacity after 5 years, versus 70% for alkaline equivalents. Their hermetic sealing also minimizes gas generation, critical for sealed medical or aerospace systems.

When Should You Replace the CR2450NIB Battery?

Replace when voltage drops below 2.5V or every 5-7 years, even in low-use scenarios. Symptoms include erratic device behavior or failure to transmit signals. Use a multimeter for testing: a reading under 2.8V under load indicates replacement. For implantable devices, follow manufacturer guidelines—Medtronic recommends proactive replacement at 80% capacity to prevent failures.

How to Properly Store and Handle the CR2450NIB?

Store at 15°C-25°C in <50% humidity. Avoid bulk storage in conductive containers—use original anti-static trays. Handle with clean gloves to prevent skin oils from corroding contacts. For disposal, follow EPA guidelines: lithium batteries require recycling at certified facilities like Call2Recycle drop-off points.

Can the CR2450NIB Be Used in Extreme Environments?

Yes. It passed MIL-STD-810G testing for vibration (20-2000Hz) and shock (100G). In subzero temperatures, its ethylene propylene diene terpolymer (EPDM) gasket prevents brittleness. Honeywell uses it in Arctic pipeline sensors where temperatures hit -40°C, relying on its stable output where other cells fail below -20°C.

What Innovations Set Renata’s Design Apart?

Renata’s laser-welded canister-to-lid interface eliminates traditional epoxy seals prone to degradation. Their proprietary MnO2 cathode mix increases surface area by 30%, boosting current delivery. A 2023 teardown by EE Times revealed micro-channel electrolyte distribution, a patented feature preventing dry-out in high-drain applications.

Expert Views

“Renata’s CR2450NIB solves two industry pain points—voltage stability under pulsed loads and shelf life. Our testing showed just 0.3V sag at 20mA pulses, versus 0.8V in competitors. For IoT nodes transmitting in bursts, this means 20% fewer packet losses. Their hermetic sealing process is unmatched—helium leak rates under 1×10⁻⁸ atm·cc/sec, critical for implantables.”

FAQ

Q: Is the CR2450NIB rechargeable?

A: No—it’s a primary (non-rechargeable) lithium cell. Attempting to recharge it may cause rupture or fire.

Q: Can I substitute it with a CR2032 battery?

A: No. The CR2450NIB has 3x the volume and double the capacity. Using smaller cells risks device damage from voltage drop.

Q: Does it work in GPS trackers?

A: Yes, but verify current requirements—it supports up to 15mA continuous. For trackers needing 20mA+, consider Tadiran TL-5930.
