Renata Batteries’ ICR2430 rechargeable lithium-ion button cell has a nominal voltage of 3.7 V and a nominal capacity of 100 mAh. Thanks to its special ‘stacked electrodes’ technology, the internal resistance of these devices is significantly reduced when compared to standard button cells, which means higher charging and discharging currents can be achieved, a maximum of 100 mA and 200 mA respectively.
The ICR2430 is characterised by high energy density and cycle stability across its entire service life, with outstanding reliability. After 500 charging/discharging cycles and in ordinary use, it will still have a residual capacity of over 80%, and thanks to its mechanical construction as a button cell in a metallic housing, the ICR2430 is perfect for applications where a great deal of mechanical stress is expected.
The device works with a charging voltage of 4.2 V (cut-off current 2 mA) and has a discharge cut-off voltage of 3.0 V. The temperature during charging is 0°C to 45°C, and the temperature during discharge is -20°C to 60°C, with a recommended storage temperature of 0°C to 45°C if storing units for more than 3 months.
The standard packaging is gold-plated, 24.5 mm in diameter, 3 mm thickness, with a weight of 4.2 g. Renata can also do board-mount and tabbed versions of the battery for easier, flatter design integration. Safety circuitry is not included within the standard cell.
