Buying Guide for High Amp Hour Batteries

Understanding Amp Hours

When I first started looking into batteries, I quickly learned that amp hours (Ah) are crucial for determining a battery’s capacity. Amp hours measure how much current a battery can supply over a specific period. For instance, a battery rated at 100Ah can theoretically provide 5 amps for 20 hours. Understanding this helped me evaluate my power needs.
