Charging vs Temperature
VOLTS PER CELL
The charging of Carefree batteries is best accomplished in a temperature range of 60°F
to 90°F. Charging within this temperature range requires no temperature compensation.
For applications over a wider temperature range, charging voltage must be changed as a
function of temperature. (see chart at right)

Capacity vs Temperature
The efficiency of the lead-acid system decreases as the temperature decreases and increases
as temperature increases from room temperature (77°) as illustrated. These four curves
shown are based on discharges at the 20 hour, 5 hour,
Self-Discharge Characteristics
High temperature increases the rate of self-discharge of all battery systems but even in
this respect, the lead-calcium battery is perhaps least affected. In general, the rate of
self-discharge can be expected to double for each 20°F rise in temperature above 70°F.
Battery Operating Conditions & Cautions
Battery contains toxic material (lead) and corrosive fluid (sulfuric acid) • Charging can
produce explosive gases • Do not charge in gas tight enclosures • Charge battery in a
well-ventilated area away from sparks, flames or smoking • Use approved voltage
controlled charger • Do not short-circuit battery terminals, as this can cause an explosion or
fire • Keep batteries and chargers away from children • Charge battery as soon as possible
after use • Do not store battery in discharged state • Do not puncture, disassemble, mutilate
or incinerate • MUST BE RECYCLED OR DISPOSED OF PROPERLY
Installation Care
All CAREFREE batteries are carefully assembled and with proper charging will provide
excellent service. When placing the battery into service it must be inspected to make sure
that the battery has not been damaged by rough handling. If the unit has been damaged,
corrosion of adjacent components. Any sulfuric acid can cause severe burns to the skin
and eyes. If contact is made with a damaged battery, immediately wash the contacted area
with water for at least 5 minutes. When installing the battery in equipment, ventilation must
be provided. Toward the end of charge and under overcharge conditions, hydrogen and
oxygen gas can be generated. If this gas is allowed to accumulate in the enclosure and a
spark is introduced, an explosion could result.
