It was essential to determine how much energy I required for my applications, whether it was for RVs, solar power systems, or electric vehicles. Knowing the wattage and the duration of use helped me decide on the appropriate amp-hour (Ah) rating.

Types of 12V High Ah Batteries

I learned that there are different types of 12V batteries available, including lead-acid, lithium-ion, and AGM (Absorbent Glass Mat). Each type has its advantages and disadvantages.
