Trojan SAGM 12 205 (Solar AGM Battery 12V 205Ah)
Operating Temperature -4°F to 113°F (-20°C to +45°C). At temperatures below 32°F (0°C) maintain a state of charge greater than 60%. Self Discharge <3% per month depending on storage temperature conditions. Chemical reactions internal to the battery are driven by voltage and temperature. The higher the battery temperature, the faster chemical reactions will occur.
While higher temperatures can provide improved discharge performance the increased rate of chemical reactions will result in a corresponding loss of battery life. As a rule of thumb, for every 10°C increase in temperature the reaction rate doubles. Thus, a month of operation at 35°C is equivalent in battery life to two months at 25°C. Heat is an enemy of all lead-acid batteries, FLA, AGM and gel alike and even small increases in temperature will have a major influence on battery life.
Deep-cycle batteries used in off-grid and unstable grid applications are heavily cycled at a partial state of charge (PSOC). Operating at PSOC on a regular basis can quickly diminish the overall life of a battery, which results in frequent and costly battery replacements. To address the impact of PSOC on deep-cycle batteries in renewable energy (RE), inverter backup and telecom applications, Trojan Battery has now included Smart CarbonTM as a standard feature in its Industrial and Premium flooded battery lines.
