Further sources of danger from LiFePo4 batteries
-
While working on a li-ion battery wear protective eyeglasses and clothing.
-
Any uncovered battery material such as electrolyte or powder on the skin or in the eyes must
immediately be flushed with plenty of clean water. Then seek medical assistance. Spillages
on clothing should be rinsed out with water.
-
Explosion and fire hazard. The terminals of a li-ion battery are always live, therefore do not
place metallic items or tools on top of a li-ion battery. Avoid short circuits, too deep
discharges and too high charge currents. Use insulated tools. Do not wear any metallic items
such as watches, bracelets, et cetera. In case of fire, you must use a type D foam or CO2 fire
extinguisher.
-
Do not open or dismantle the battery. Electrolyte is very corrosive. In normal working
conditions contact with the electrolyte is impossible. If the battery casing is damaged do
not touch the exposed electrolyte or powder because it is corrosive.
-
Li-ion batteries are heavy. If involved in an accident they can become a projectile! Ensure
adequate and secure mounting and always use suitable handling equipment for
transportation.
-
Handle with care because a li-ion battery is sensitive to mechanical shock.
-
Do not use a damaged battery.
-
Do not wet the battery.
Charging and discharging
-
Too deep discharges will seriously damage a li-ion battery and can even be dangerous.
Therefore, use of an external safety relay is obligatory.
-
Use only with a manufacturer approved BMS.
-
If charged after the Lithium Battery was discharged below the “Discharge cut-off voltage”,
or when the Lithium Battery is damaged or overcharged, the Lithium Battery can release a
harmful mixture of gasses such as phosphate.
-
The temperature range over which the battery can be charged is 5°C to 50°C. Charging the
battery at temperatures outside this range may cause severe damage to the battery or
reduce battery life expectancy.
-
The temperature range over which the battery can be discharged is -20°C to
50°C. Discharging the battery at temperatures outside this range may cause severe
damage to the battery or reduce battery life expectancy.
