Yes, a deep cycle battery can be a wet battery. Flooded lead-acid (wet cell) batteries are a common type used for deep cycle applications. These batteries require the user to refill the electrolyte levels periodically to maintain the battery's performance.
Understanding Deep Cycle and Wet Cell Batteries
-
Deep cycle batteries are designed for repeated deep discharges and recharges, unlike starting batteries which primarily provide short bursts of high power. They are commonly used in applications like RVs, boats, and solar power systems.
-
Wet cell batteries (also known as flooded lead-acid batteries) contain liquid electrolyte. This electrolyte needs to be topped off periodically as it is lost through gassing during use. The vent caps on top of the battery allow for this maintenance.
Several sources confirm this relationship:
- Battery Guys: States that "Flooded or "wet cell" batteries are used in deep cycle applications" https://batteryguys.com/pages/the-differences-between-agm-gel-and-flooded-batteries
- Batteries in a Flash: Clearly states that "Flooded lead acid (wet cell) batteries are one of the most common types of battery for deep cycle applications." https://www.batteriesinaflash.com/deep-cycle-battery-faq
- Continental Battery: Explains that "Flooded deep cycle batteries will require the user to refill the electrolyte levels to maintain the battery..."https://www.continentalbattery.com/blog/what-s-the-difference-between-a-deep-cycle-battery-and-a-regular-battery
However, it's important to note that not all deep cycle batteries are wet cell batteries. Other types, such as AGM (Absorbent Glass Mat) and gel cell batteries, are also used in deep cycle applications but do not require electrolyte topping.
