Introduction to the Pyronix CR2450 3V Coin Battery Pack (5)
Pyronix BATT-CR2450Ris a slim, reliable pack of five CR2450 3.0 V lithium coin cells designed primarily as replacement batteries for Pyronix wireless sensors, notably the MCNANO-WE series. Supplied as a convenient sleeve/strip of five cells, this pack is aimed at installers, maintenance personnel and homeowners who want to keep spare batteries on hand for low-drain security devices. The CR2450 form factor is a common choice where slightly larger capacity than slimmer coin cells is needed without increasing device size.

- Packaging: Sleeve/strip of 5 — keeps batteries organised and easy to store or carry on a service job.
- Reliability: Lithium Li-MnO2 chemistry is known for a stable discharge profile and long shelf life, making these cells suitable for backup and standby applications.
- Convenience: A five-pack means fewer trips to the store and straightforward replacement for household security sensors.
- Cost-effectiveness: Buying a multi-pack reduces cost per cell compared with single sales; the suggested retail price positions this pack competitively for both consumers and trade customers.
- Compatibility: Supplied specifically as a Pyronix replacement—ideal for installers who need vendor-approved parts for warranties and compatibility checks.
Use cases and scenarios where the Pyronix CR2450 excels
The CR2450 format is a versatile coin cell used across a range of low-current electronics. The Pyronix pack targets several clear scenarios:
Wireless door/window contacts, shock sensors, and other battery-operated components in alarm systems commonly use CR2450 cells. The slightly larger capacity of CR2450 cells compared with thinner coin cells yields longer intervals between battery replacements — an important practical advantage for devices installed in hard-to-reach locations.
Many small devices — such as some temperature sensors, wireless remotes, and certain IoT endpoints — benefit from the 3.0 V and higher capacity offered by CR2450 cells. Where a device specification calls for a CR2450, these Pyronix batteries provide a direct and reliable fit.
For security system installers and service technicians, carrying a strip of five replacement cells means faster on-site servicing and consistent parts across installations. The Pyronix-branded pack gives confidence in compatibility with Pyronix sensors, simplifying stock management for trade professionals.
Comparisons with similar products on the market
When choosing coin cells, buyers often consider alternatives such as CR2032, CR2025, and cells of the same size from other manufacturers (e.g., Murata, Panasonic, Maxell). Here’s how the CR2450 pack compares:
- Capacity: CR2450 cells typically offer significantly higher capacity (around 500 mAh) compared with CR2032 cells (typically ~200–240 mAh). This means longer operational life in low-drain devices for CR2450.
- Size: The CR2450 is thicker (5.0 mm vs 3.2 mm) and slightly larger in diameter, so it only fits in devices designed for CR2450.
- Use case: Choose CR2450 when the device specifies it or where longer battery life is needed and the device supports the larger form factor.
Many reputable manufacturers produce CR2450 cells. The Pyronix BATT-CR2450R is marketed as a compatible replacement for Pyronix devices, which can be important where manufacturer-recommended parts are preferred for warranty or performance assurances. Buyers comparing across brands should consider:
- Datasheet specs (capacity, discharge curve, maximum continuous load, operating temperature range).
- Packaging and batch traceability for professional installers.
- Price per cell and availability in multi-packs versus single units.
In many cases, established cell manufacturers (Murata, Panasonic, Sony/Maxell) will have near-identical electrical performance; the deciding factors often become part availability, packaging, and supplier confidence.

Safety, disposal and installation notes
As with all coin cells, handle Pyronix CR2450 batteries with care. Important safety points include keeping cells away from children, not attempting to recharge primary lithium cells, avoiding short circuits or punctures, and following the device manufacturer’s instructions when replacing batteries. Dispose of used batteries in accordance with local regulations — recycling is recommended to recover materials and prevent environmental harm.
