How Long Will 100ah Battery REALLY Last? (Explained!)
For most accurate estimate: Use this calculator for loads of up to 250W with 12V 100Ah lead acid and up to 600W with 12V 100Ah lithium-ion. I''ll explain the reason later in this article. calculator Assumptions. The result takes into account the efficiency of an inverter (90%) and the efficiency of the battery discharge (lead acid: 85%, Lithium: 95%).
