VARTA CR 2430
The VARTA CR 2430 is a lithium coin cell battery for equipment requiring a small, round 3 V power source with a long service life and stable voltage. It is a primary cell, meaning it is designed to be replaced once depleted and is not rechargeable.
This type is typically used in compact electronics where space is limited but the battery must still provide long-term operation. Size is key here: 24.5 mm in diameter and 3.0 mm in height. Weighing approximately 4 g, it takes up very little space in the overall design.
The cell technology is lithium manganese dioxide with an organic electrolyte. In practice, this means a 3 V cell with a typical capacity of 300 mAh measured at a 5.6 kΩ load at 20 °C down to 2.0 V. It is also rated to operate within a wide temperature range, from -20 °C to 70 °C, and can be stored at temperatures down to -55 °C.
It is a relevant replacement part for keeping small electronic devices running without frequent battery changes. The CR 2430 is well-suited for applications where low power consumption and stable operation are more important than high discharge current.
