Coin-cell power for compact devices

The Ultralast UL2430 is a 3 V lithium coin cell rated at 280 mAh. It fits devices designed for the 2430 form factor such as motherboards, remotes, medical instruments and small sensors. The cell is supplied as a single unit ready for immediate installation.

Suitable for primary-cell slots only

This battery is not rechargeable, so it cannot be used in circuits that expect a secondary cell or a charging current. Buyers who need a rechargeable 2430-size cell or a higher-capacity primary cell should look at a different chemistry.

280 mAh capacity at 3 V

The rated capacity of 280 mAh at 3 V determines how long the cell can power a given load before voltage drops below the device threshold. Match this figure to the equipment’s current draw to confirm suitability.
