These batteries have been used in off-grid power systems in remote cabins for the past 25 years with great success. Because of their low initial cost, they are the most affordable true, deep cycle batteries. The T105 golf cart battery is designed to be used in small electric vehicles where they are cycled heavily and last about 2 years. In a remote home system where they are cycled down 20% every day they can last 3 to 6 years. The L-16 battery is designed for electric floor scrubbing machines. They are a heavy-duty cousin of the golf cart battery with much thicker lead plates and nearly twice the capacity. The L-16 is available in a standard and a high-capacity version. The standard version holds more electrolyte and has a slightly longer life.

     The SCS-series 12-volt marine batteries are Trojan’s top of the line 12-volt deep cycle batteries. They are designed for marine and RV use and work well in small cabin systems where 110 to 130 amp-hours is enough storage.
