Why the CP723434 is the Hardware Engineer’s Choice
1. The Perfect Square Profile ( 34x34mm)
Most IoT sensors, active RFID tags, and smart cards utilize square or rectangular PCBs. The CP723434’s matching square footprint maximizes internal space utilization, allowing you to design sleek, modern enclosures without wasting a single millimeter.
2. High Energy-to-Weight Ratio
At just 14g, this battery reduces the overall payload of wearable devices, personal tracking devices, and portable medical instruments. By utilizing a flexible, laminated aluminum foil pouch instead of a heavy steel casing, it sheds unnecessary weight while maximizing active chemical volume.
3. Reliable Performance in Harsh Climates (-40°C to +60°C)
Whether your assets are tracked through freezing cold-chain logistics or deployed in remote, sun-baked outdoor environments, the CP723434’s stable organic electrolyte ensures reliable voltage delivery and pulse current capability.
4. Over a Decade of Operational Standby
With an exceptionally low annual self-discharge rate of under 2%, this cell preserves its energy capacity over long periods. It is the ideal power source for devices that remain in standby or low-power sleep modes for years before activation.
5. Inherent Safety Profile
The flexible soft pack design functions as a built-in safety valve. In the rare event of extreme physical damage or electrical abuse, the laminated pouch expands gradually to relieve internal pressure, eliminating the explosion and fragmentation risks associated with rigid-casing batteries.
