The Haus Strom 220Ah 12V tubular battery is a deep-cycle, tall-tubular lead-acid battery engineered for solar and inverter backup systems. It employs tubular positive plates and thick separators for enhanced cycling ability, better deep discharge recovery, and durability. With features such as a water/float gauge for checking electrolyte levels, stainless steel connectors to minimize corrosion, and a strong polypropylene container to resist shocks and high ambient temperatures, it offers reliable, low-maintenance power storage. Capacity of 220Ah at 12 volts gives substantial run-time in medium loads, with an expected life of 3-5 years under normal use.
