UBT
Salicru's UBT series batteries are extremely powerful and compact rechargeable lead-lead dioxide energy accumulators particularly suitable for UPSs and other security systems that require reliable and high-quality energy back-up.
Salicru's UBT battery range includes 4.5 Ah, 7 Ah, 9 Ah, 12 Ah, 17 Ah, 24 Ah, 45 Ah, 55 Ah, 65 Ah, 90 Ah and 100 Ah models, all at 12 V.
The sulphuric acid electrolyte is absorbed by the separators and plates. And these in turn immobilised. They are designed using gas recombination technology which eliminates the need for the regular addition of water by controlling the evolution of hydrogen and oxygen during charging. The battery is completely sealed and watertight and therefore maintenance free, enabling it to be used in any position. If the battery is accidentally overcharged, resulting in the production of hydrogen and oxygen, a number of special one-way valves allow the gases to escape to avoid interior overpressure.
Uninterruptible power supply systems (UPS), emergency lighting systems, signalling systems, communications and electrical equipment, broadcasting systems, lift automation panels, electronic cash registers, etc.
The number of cycles a battery can perform depends on the depth of discharge that is reached with each use. Thus, if we reach an ideal depth of discharge of 30%, we obtain an exponential increase in the number of cycles available. It is very important to take this factor into consideration when calculating the backup time required and lifespan in comparison to frequency of discharge.
Charging at a constant voltage, equivalent to the equalisation voltage, requires around eight hours in order to reach a volume of approximately 80%, which places the battery in optimum working mode and ensures it is in the best condition to perform a discharge cycle.
Operating at ambient temperatures outside the normal range (25°C) requires the charger to modulate the charge voltage correctly. If your device does not have a voltage compensation function, the battery usually suffers, regardless of whether its use is cyclical or less intensive.
Ensuring the correct ambient working temperature is key to making sure that the battery’s lifespan remains within the guaranteed time-frame and that performance remains optimal.
