Lead batteries are designed as either flooded or valve-regulated, depending on the needs of a particular application or the end-users preference. Flooded, also known as wet cell batteries, power a wide range of industrial and automotive applications. We’ll discuss what flooded lead batteries are, the differences between these batteries and sealed batteries, and the advantages of using this battery type.

What Are Flooded Lead Batteries?

The name of these batteries comes from the surplus of electrolyte fluid within the battery, which “floods” the plates so they’re entirely submerged. It’s important to mount these batteries in an upright position to prevent the electrolyte from leaking out of the battery’s caps toward the top of the encasement.

These batteries can be more affordable with a low upfront cost in automotive and industrial truck applications.  Although cost-effective in specific applications, they also require regular maintenance in industrial applications to reach their potential lifespan. This entails checking the battery on a regular basis and topping it off using distilled water.

What Is the Difference Between a Flooded vs. Sealed Battery?

Flooded and sealed batteries share similarities in their weight and size, but they’re also different in several key ways.

The biggest difference between these batteries is their maintenance requirements. Flooded batteries require the occasional addition of distilled water, along with equalization in industrial applications. They also require users to measure the gravity of the electrolyte using a hydrometer. Additionally, flooded lead batteries may also off-gas hydrogen under some circumstances, culminating the need for proper ventilation to release fumes.

On the other hand, and depending on the application, flooded batteries can be considerably more cost-effective for upfront purchases than maintenance-free sealed batteries.  However, it is important to determine the total cost of ownership for your application when deciding to purchase a flooded or VRLA lead battery. 

What Are the Key Benefits of Using a Flooded Lead Battery?

Flooded lead acid batteries come with several main advantages, including:

  • High discharge rate capability
  • A lower initial cost in automotive or industrial truck applications
  • Can demonstrate a longer life vs. VRLA in certain industrial applications
  • Can demonstrate improved performance in hot climates of 90° F 
  • More international availability

These benefits make flooded lead batteries highly versatile and compatible with a wide variety of applications, particularly as a solution for the automotive industry or industrial backup power in which both ventilation and maintenance are possible.
