Provide a periodic freshening charge to maintain a SOC greater than the
threshold of 70%.
EXPECTED LIFE VS. TEMPERATURE
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.
SMART CARBON™
Deep-cycle batteries used in off-grid and unstable grid applications
are heavily cycled at 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 Carbon™ as a standard feature in its Solar Industrial and
Solar Premium flooded battery lines.
