Battery Safety Precautions, continued
Check the electrolyte temperature from time to time. The temperature of the •
electrolyte should never exceed 45 °C as higher temperatures have a detrimental
effect on the function and duration of the cells. In the course of charging an
electrolyte temperature of ≤ 35 °C should be aimed for. On exceeding 45 °C the
charging should be temporarily interrupted until the electrolyte temperature falls
down to 35 °C. The temperature measurements are to be made on one of the cells
in the middle of the battery. Low ambient or electrolyte temperatures down to –25
°C do not have any detrimental effect on the battery they just cause a temporary
reduction in capacity.
NiCd batteries must not be stored in the same room as lead acid batteries. Also, the
•
charging gases from lead acid batteries must be kept away from Ni-Cd batteries by
suitable precautions such as ventilation or hermetic isolation of the rooms. Tools for
lead acid batteries must not be used for NiCd batteries
Do not place electrically conductive objects (e.g., tools) on the battery as this is a •
short circuit and fire hazard.
Do not wear rings, metal bracelets, watches, or jewelry when working with the •
batteries and battery systems.
Provide sufficient ventilation (e.g., open the doors of the battery cabinet) during •
charging so any accumulated gases can escape. The charging gases from batteries
are explosive.
Do not allow open fire or ember in the vicinity of the battery. •
Caustic potash solution is used as electrolyte, and is a highly corrosive liquid which •
can cause severe damage to health if it comes into contact with the eyes or the
skin (risk of blinding). If even small quantities are swallowed there is a possibility of
internal injuries.
Contact with the eyes: Flush out immediately with copious amounts of water for 10
•
to 15 minutes, and seek immediate medical attention.
Contact with the skin: Remove splashed clothing immediately and wash the affected
•
skin areas with copious amounts of water, and seek immediate medical attention.
Swallowing: Rinse out the mouth immediately with large amounts of water and
•
keep drinking large amounts of water. Do not induce vomiting, and seek immediate
medical attention.
