CR2450 3V Lithium Coin Batteries

Where is a CR2450 3V battery used?

A CR2450 lithium battery is commonly used in remote controls, smart home sensors, medical accessories, calculators, LED candles, electronic scales, car key modules, backup memory circuits and small measuring devices. The cell format is approximately 24.5 mm in diameter and 5.0 mm high, so it is important to match both the code and the physical size before ordering.

CR2450 price and value

When comparing the CR2450 price, consider not only the unit cost but also the brand, expiry date, pack quantity and how often your device is used. Lithium coin cells have a low self-discharge rate, making them convenient to keep as spares for household electronics, security accessories and seasonal devices.

Tip: Do not replace a CR2450 with a thinner coin cell such as CR2032 unless your device manufacturer explicitly allows it. Even if the voltage is the same, the thickness and contact pressure may be different.
