Battery Maintenance

Maintenance and how to care for your deep cycle batteries

Batteries vary by chemistry and configuration, which means that the required maintenance also changes. Some of these maintenance tasks may be automated or performed remotely via charge controllers or battery management systems, including charge regulation, voltage checks, and related measurements. Others require on-site manual operations or oversight. These tasks include, but are not limited to, adding water or equalization. Sealed …

Trojan GEL Deep-Cycle Batteries

Deep-Cycle Gel Batteries

Deep-cycle Gel batteries also work on the same principle of oxygen recombination but use a different method to achieve it. They use a composite separator composed of a glass mat bonded to a porous polyethylene or polyvinylchloride sheet. The batteries are filled with a thixotropic gel of silica mixed with sulfuric acid. When this is added to the battery it …

Trojan Absorbed Glass Mat (AGM) Batteries

Absorbed Glass Mat (AGM) Batteries

Deep-cycle AGM batteries incorporate a porous glass mat separator that has the ability to absorb a large amount of electrolyte while still allowing some of the pores to be unfilled. These empty pores act as channels which allow oxygen to move from the positive to the negative plates. This absorptive glass mat is a critical component of the battery since …
