Product overview
Grepow’s GRP2452FL is a rechargeable lithium-ion button cell developed for compact equipment operating in cold environments, including trackers, small GPS devices and aerospace sensors. Its circular body measures 24mm in diameter and 5.2mm thick, with a weight of 7.1±0.5g. Stacked-electrode construction forms the physical architecture, while LiCoO2 chemistry provides a nominal 3.8V and 285mAh capacity. These dimensions define its integration envelope; customization options cover diameter, thickness, shape, capacity and voltage for equipment with different internal space requirements.
The GRP2452FL has nominal charging and discharging currents of 142.5mA/0.5C, with maxima of 285mA/1C for each. Charging uses a 4.35V cutoff and requires temperatures from 0 to +45°C, whereas discharge extends from -50 to +60°C with a 3.0V cutoff. Cold-temperature discharge capability therefore comes with a separate, warmer charging requirement. Storage spans -20 to +40°C. Internal resistance is ≤120mΩ, and cycle life exceeds 1000 cycles at 0.5C charging and 0.5C discharging. Certifications are UN 38.3 and IEC 62133.
