Salicru UBT 12/12, Sealed Lead Acid (VRLA), 12 V, 12 Ah, 1 pc(s), 5 year(s), Black

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 and 17Ah 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.
