The Interstate CR2450 3V is a lithium coin/button battery designed to power small electronics that require dependable, long-lasting performance. With the IEC designation CR2450 and a nominal output of 3 volts, it serves as a direct replacement part for devices that specify CR2450 cells, including key fobs, remotes, calculators, wearable fitness sensors, medical devices, LED lights, bike computers, garage door openers, and various sensors found in residential and commercial applications. It is a universal fit for electronics calling for CR2450 and commonly cross-references to DL2450 and ECR2450.
This primary (non-rechargeable) lithium cell uses Li‑MnO2 chemistry for stable voltage delivery across low and intermittent pulse loads. The positive terminal is the top side, and the negative terminal is the flat underside; install by aligning polarity as indicated in the device. Use only in equipment that specifies CR2450; do not mix old and new cells or different chemistries. For safety, do not recharge, disassemble, or short-circuit, and keep coin cells out of reach of children; follow local regulations for disposal. The Interstate CR2450 3V coin battery is a reliable upgrade or replacement for compatible electronics where a compact, high-energy 3V button cell is required.
