What type of battery is commonly used in an RV's 12v system?

Lead Acid
Lithium Ion
Nickel Cadmium
Alkaline

The correct answer is: Lead Acid

Lead Acid batteries are commonly used in an RV's 12v system due to their established reliability, affordability, and availability. These batteries come in various forms, with flooded lead-acid and sealed lead-acid (AGM and gel) being the most prevalent in recreational vehicles. Flooded lead-acid batteries are known for their durability and ability to handle deep discharges, making them suitable for the cyclic nature of RV use, where power is drawn and recharged frequently. Sealed lead-acid batteries have the added benefit of being maintenance-free, which is advantageous for RV owners who may not frequently check or maintain their battery levels. While Lithium Ion batteries are increasingly popular due to their lightweight and higher energy density, they are typically more expensive and may require specialized charging systems. Nickel Cadmium batteries are less common in RV applications due to their lower capacity and environmental disposal concerns. Alkaline batteries, while useful for small electronics, do not provide the necessary power and storage capacity for RV systems. Thus, lead-acid batteries remain the standard choice for powering RVs effectively.
