3.1.1 Ventilation
Battery room or cabinet must be ventilation. Ordinary indoor environment do not need to take
special measures to ventilation. Battery ventilation design requirements for 12.5L/2V100AH/h
according to EN 50272‐2 standard.
If charge battery with equalization voltage, ventilation quantity requirement should be as five
times as float charge.
3.1.2 Temperature
313K series 12V batteries are high temperature VRLA batteries, suit for operating at 35℃ for
long period.
Battery must be installed shade and dry environment, avoid heat and sun and humidity is less
than 90%.
Note:
This clause only applies to 313K series 12V battery; it not applies to other normal battery.
