Thanks for the question! Based on the name mentioning "deep cycle", the Probe Xtreme Deep Cycle 110ah Battery you asked about is most likely a tubular lead-acid battery. Tubular batteries like it are very popular for deep cycle applications like solar energy storage because of their sturdy construction and ability to withstand many charge/discharge cycles. The Solarix Luminous 12V 180AH Flooded Tall Tubular battery in the search results looks quite similar, and at R4299.99 it seems a well-priced option too. Let me know if you need any other details on deep cycle battery types!
