Construction and operation principles.
When using lead acid battery as a result of electrolysis of an aqueous electrolyte solution are separated hydrogen and oxygen. These gases in air may form explosive mixtures. Additionally the electrolysis reduces the amount of water in the electrolyte, which must be relatively frequently replenish in the battery. The conversion of hydrogen and oxygen in steam is an exothermic process. The heat emitted during the recombination process inside the sealed battery significantly accelerates the degradation of the lead electrodes immersed in an electrolyte. Therefore, the process is preferably carried away from the recombination with the electrodes, thus increasing the life of the entire battery. Water vapor then condenses on the walls of plug. After cooling, as the water flows back into the battery. Recombination plug reduces maintenance the frequency of replenishing the electrolyte level in the battery and increases the safety of the battery in areas with limited ventilation.
- LIFETIME – more than 20 years. Classic batteries with recombination plug have much longer life than VRLA batteries, in which it is not possible to refill water.
- SAFETY– increased safety of operation of cells with fluid electrolyte (electrolyte fumes and poisonous gases do not leak from the battery into the immediate surroundings). None of the gases capable of causing explosions are released into the surrounding area.
- ECONOMY– significantly reduced the frequency of water refilling (12-15 years topping-up interval), recombination plugs are optimized to work in full lifetime of the battery. Reduced need for ventilation; battery rooms equipped with cells using recombination plugs require less ventilation.
- FLEXIBLE – the ability to match amount of plugs to specific capacity of batteries.
For appropriate operation of recombination plug the cell must be properly sealed . Special construction of pillars’ grommets and precise gluing of lids – confirmed with pressure test – causeshat recombination plugs are excellently working with SLA BATER cells (OPzS and SOPzS).
