3.8 Ventilation
Deep-cycle ooded/wet lead acid batteries release small amounts of gas during usage, particularly
during the charging process. Deep-cycle AGM and gel batteries do release gas, but at a much lower rate
than the ooded types. It is critical to charge batteries in a properly ventilated area. For more assistance in
determining ventilation needs, please contact Trojan Battery Company’s technical support engineers.
3.9 Battery Orientation
Deep-cycle ooded/wet batteries must be placed upright at all times. Fluid in the battery will spill if the
battery is placed on its side or at an angle. Deep-cycle AGM or gel batteries are non-spillable and can be
placed either upright or on their side.
3 .10 Battery Environment
Batteries should be stored and installed in a clean, cool and dry place, keeping water, oil, and dirt away
from the batteries. If any of these materials are allowed to accumulate on the batteries, tracking and
current leakage can occur, resulting in self-discharge and possible short-circuits. Battery chargers should
also be installed in well-ventilated, clean areas that are easily accessible.
3 .11 Temperature
The recommended operating temperature range is between -4°F to 122°F (-20°C to +50°C) with a
humidity of <90%. Elevated battery electrolyte temperatures of >80°F (27°C) will reduce operating life,
while lower battery electrolyte temperatures of <80°F (27°C) will reduce battery performance.
It is important to minimize temperature variations between the cells, therefore, do not arrange the
batteries where they are too tightly packed together which restricts airow. The batteries should have a
minimum of 0.50” (12.7 mm) of space between them to allow for adequate airow.
