Flooded Lead-Acid Battery Overview
Flooded lead-acid batteries (FLA batteries for short) are a tried and true technology that has been around for more than 160 years. These batteries are built with lead plates submerged in an electrolyte (a mix of distilled water and sulfuric acid).
Flooded batteries require routine maintenance to operate properly. The main responsibility is refilling the battery with distilled water 1-2 times a month to replace water that evaporates during use.
For a complete overview of what it takes to maintain flooded batteries, check out our battery maintenance guide.
Pros of flooded lead-acid batteries:
Lowest upfront cost
Cons of flooded lead-acid batteries:
Require routine maintenance to stay in working condition
Must be ventilated due to off-gassing as a byproduct of operation
Shallow discharge: other battery types can use more of their capacity before recharging
