Flooded lead-acid batteries have the longest track record in solar electric use and are still used in the majority of stand-alone alternative energy systems. They have the longest life and the least cost per amp-hour of any of the choices. However the other side of the coin is, in order to enjoy these advantages, they require regular maintenance in the form of watering, equalizing charges and keeping the top and terminals clean (please refer to our maintenance guide on how to care for these batteries). Some examples of flooded lead-acid batteries used in solar and wind electric systems are 6 volt golf-cart batteries, 6 volt T105's and 2 volt industrial cells for large systems.Specially designed deep-cycle cells are much less susceptible to degradation due to cycling and are required for applications where the batteries are regularly discharged, such as photovoltaic systems, electric vehicles (forklift, golf cart, electric cars and other) and uninterruptible power supplies. These batteries have thicker plates that can deliver less peak current, but can withstand frequent discharging. Trojan Battery Company is the world leader in deep cycle battery technology. Since 1925, Trojan has been a pioneer in the development of superior deep cycle batteries. Decades of experience, ongoing research and dedication go into every deep cycle battery we manufacture. The bottom-line? You can depend on Trojan to deliver reliable, long lasting, continuous power and exceptional value. That's the Trojan advantage
