Battery Tips
Explosive/
Corrosive
Gases
Lead-acid batteries may emit hydrogen gases, oxygen, and sulfuric acid
fumes when recharging. To reduce the risk of explosion:
•
Vent the battery compartment to prevent the accumulation of gases.
•
Do not install electronic or electrical equipment in the battery
compartment.
•
Do not smoke or use an open flame when working around batteries.
Temperature
Sensitivity
The capacity of lead-acid batteries is temperature sensitive. Battery
capacity is rated at 77 ºF (25 ºC). At 0 ºF (–20 ºC), the Ah capacity is
about half the rated capacity. You should consider temperature when
designing your system.
•
Low Temperatures
If extremely low temperatures are expected
where the inverter is going to be located, you should consider a
heated equipment room. If the system is located in an unheated space,
an insulated battery enclosure is recommended.
•
High Temperatures
The batteries should also be protected from high
temperatures. These can be caused by high ambient temperatures,
solar heating of the battery enclosure, or heat released by a nearby
engine or generator. High battery temperatures shorten battery life
and therefore you should ventilate the enclosure and use shade and
insulation as appropriate.
Discharged
Batteries
Do not leave batteries in a discharged state for more than a day or two.
They will undergo a chemical process (sulfation) that can permanently
damage the battery. As well, batteries self-discharge over a period of three
to six months, and they should be recharged periodically even if they are
not being used.
Electrolyte
Level
If your batteries are not the “maintenance-free” type, check the electrolyte
level at least once a month. Excessive fluid loss is a sign of overcharging.
Replenish the electrolyte using only distilled water.
WARNING
Review “Precautions When Working With Batteries” on page vi before you work
with the batteries in your system.
