Deep cycle batteries are tailored to tolerate slow and gradual discharge and recharge cycles over extensive periods. Such batteries are ideal for RVs, as well as solar energy storage units and uninterruptible power supplies, because the thick plates of deep-cycle batteries are designed to endure repeated discharges. Starting batteries, by contrast, excel at short bursts of high-caliber power needed to ignite motors. Such batteries utilize thin plates that enable rapid power release but are incapable of enduring deep discharge. Knowing the distinctions, such as the construction of each battery, is vital for determining how to choose a battery for a given application.
