6 FAQs about [Open battery cabinet in weak current room]
Where should a standby power battery be housed?
Batteries can be housed satisfactory in almost any reasonably well ventilated and illuminated room. As the life of a standby power battery is heavily dependent upon regular maintenance. This is much more likely to be done effectively if there is easy access to each cell and good lighting. Exposure to direct sunlight however is not recommended.
How should a battery room be ventilated?
The battery room should be sufficiently well ventilated to prevent the accumulation of hydrogen and oxygen given off during recharging. As hydrogen is lighter than air and is likely to concentrate near ceiling level, air bricks and vents should be sited high up on outside walls and unvented structural pockets in the ceiling should be avoided.
Should batteries be placed in the middle of a building?
Batteries should not be sited in the middle of the building unless special arrangements, such as ducting, are made to pass extracted hydrogen through the roof or an outside wall. The labyrinth type vent plugs on cells are designed to prevent the release of acid vapour from the cells under normal conditions.
How should a battery room be inspected?
For good natural lighting and ventilation, battery rooms should have opening windows high in the walls, with blinds to prevent direct sunlight shining on the cells. Hot direct sunlight can cause separations to become bleached. Artificial lighting should also provide sufficient lighting for cells to be inspected and readings taken.
What temperature should a standby battery be kept at?
High temperatures increase the capacity of the cells, but decrease the life, while low temperatures reduce the capacity temporarily but have no long term adverse effect. The standard capacity rating for a standby battery, is at a temperature of 25c and it is therefore advisable that the battery room be kept as near to this temperature as possible.
What should a battery room look like?
At temperatures below that level the battery may not have sufficient capacity to perform its required duty. For good natural lighting and ventilation, battery rooms should have opening windows high in the walls, with blinds to prevent direct sunlight shining on the cells. Hot direct sunlight can cause separations to become bleached.
