The Siemens 6GT2803-0CA00 is a lithium-ion accumulator intended as the spare battery for the SIMATIC RF300 system, specifically the RF350M handheld reader. It provides 7.4 V rated voltage with 2600 mAh capacity and a typical load time of 5 h. The design allows quick exchange in the field, minimizing downtime when the primary battery depletes.
Environmental limits for storage and operation
Storage temperature range is -20 to +60 °C; operating temperature is specified as 55 to -20 °C (note the reversed order in the source — the upper limit is 55 °C, lower -20 °C). These bounds suit typical industrial environments but not extended high-heat or freezing conditions without derating.
