Safety Instructions for Lead-Acid Batteries
While charging lead-acid batteries explosive or hazardous
gasses can develop. For this reason charge lead-acid batteries
only in well-ventilated areas. Avoid naked flames and sparks.
Do not charge other batteries than 12 V / 24 V lead-acid
batteries.
Do not charge old, damaged, deeply drained or otherwise
defective lead-acid batteries.
Avoid contact with the battery acid. Battery acid can cause
severe burns! In case of skin contact wash the exposed area
with liberal amounts of fresh water and, if necessary, contact a
physician. If battery acid contacts eyes, flush the eyes with water
for at least 5 minutes. Seek medical help immediately. Do not
apply eye drops without asking a physician.
During normal operation lead-acid batteries might generate
explosive gases. Explosive gas can be ignited by a cigarette or
an open flame and can damage the battery. Thereby acid will
splash out and causes serve chemical burns.
While charging, explosive and flammable substances such as
fuel or solvents should not be kept near the charger or the
battery.
Always wear safety goggles when operating the charger in the
vicinity of lead-acid batteries and avoid skin and cloth contact
with battery acid. Wear safety gloves and protective clothing.
Do not smoke in the vicinity of lead-acid batteries. Avoid open
flames.
Ensure sufficient ventilation! Discharged lead-acid batteries
freeze at extremely low temperatures! Never charge a frozen
lead-acid battery!
The efficiency of a lead-acid battery decreases with dropping
temperatures. A fully charged battery has a capacity of 40% at
an ambient temperature of -18 °C.
Most batteries will be damaged by over charging.
