The GLT Solar 230Ah 12V gel battery is a deep-cycle, maintenance-free battery ideal for solar, inverter, backup power systems. It uses gel electrolyte, which is sealed and spill-proof, meaning no need to top up with water. With its high capacity (230 ampere-hours at 12 volts), it provides reliable, longer duration power during outages. The gel construction means better resistance to vibration and temperature extremes compared to flooded lead-acid batteries.
