![]() Instead of using a gel, an AGM uses a fiberglass like separator to hold the electrolyte in place. ![]() Absorbed Glass Mat (AGM) batteries are the latest step in the evolution of lead-acid batteries.Furthermore, gel cells use slightly lower charging voltages than flooded cells and thus the set-points for charging equipment have to be adjusted. Furthermore, the thickening agent prevents stratification by preventing the movement of electrolyte.Īs Gel cells are sealed and cannot be re-filled with electrolyte, controlling the rate of charge is very important or the battery will be ruined in short order. Thus, if the battery container cracks or is breached, the cell will continue to function. Gel Cells use a thickening agent like fumed silica to immobilize the electrolyte.The water needs of flooded cells can be reduced via the use of Hydrocaps, which facilitate the recombination of Oxygen and Hydrogen during the charging process. Since the container is not sealed, great care has to be taken to ensure that the electrolyte does not come into contact with you (burns!) or seawater (chlorine gas!). Since the grid is not supported except at the edges, flooded lead-acid batteries are mechanically the weakest batteries. Each cell will feature a grid of lead plates along with an electrolyte based on sulphuric acid. The plastic container used for flooded cells will have one or more cells molded into it. Typically, the cells can be access via small ~1/2" holes in the top casing of the battery. In the marine business, they usually are not sealed so the user can replenish any electrolyte the battery vented while charging the battery. They offer the most size and design options and are built for many different uses. Flooded or Wet Cells are the most common lead-acid battery-type in use today.Currently, there are three common lead-acid battery technologies: Flooded, Gel, and AGM. The battery universe is further divided along the lines of battery construction. The reliance on lead grids and paste explains the great heft of lead-acid batteries. This energy is stored in chemical form within lead grids mounted inside the battery. Using an electrolyte consisting of sulphuric acid, these cells can store impressive amounts of electrical energy in a relatively small space. The most common kind of battery in Marine use today is the lead acid battery. Battery Types: Flooded versus AGM and Gel On the kinds of batteries we may use on board:
