Product overview
The Grepow GRP451927G1 provides rechargeable power for compact equipment, including smart wearables, medical equipment, portable devices and Internet of Things devices. Its quadrilateral body uses a stainless-steel enclosure around LiCoO2 chemistry, with automated stacking used in the battery construction. The standard model measures 4.4mm high by 19mm wide by 27mm long and weighs 7.65g. These dimensions define its physical integration envelope. Custom versions can change dimensions, shape, capacity and voltage; the stated customization thresholds are thickness ≥3.5mm and width ≥6mm.
The standard electrical configuration combines 3.85V nominal voltage with 320mah nominal capacity. Nominal charging and discharging currents are each 160mA/0.5C, with each maximum set at 320mA/1C. Charging ends at 4.4V and discharging at 3.0V. Charging temperature is limited to 0°C to +45°C, discharge temperature to -20°C to +60°C, and storage temperature to -20°C to +40°C. Cycle life exceeds 1000 cycles at 0.5C charge and discharge. Additional operating ranges of -50°C to 50°C or -20°C to 80°C have no specified configuration.
