Nominal Voltage: 12V.Rated Capacity: 200Ah (usually rated at the C10 or C20 rate).Total Energy Capacity: 1.2 kWh (1,200 Watt-hours).Cycle Charge Voltage: 14.1V to 14.4V (Gel batteries require lower charging voltages than AGM or flooded batteries to prevent drying out).Float Charge Voltage: 13.5V to 13.8V. Usable Power & EfficiencyDepth of Discharge (DoD): Recommended 50% for maximum life, though they can handle up to 80% DoD occasionally.Usable Energy: Safely provides 600Wh (at 50% DoD) to 960Wh (at 80% DoD) of real-world power.Self-Discharge Rate: Very low, typically less than 2% to 3% per month at room temperature (excellent for seasonal storage).
