Country of Manufacture: U.S.A. 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.
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.....

Trojan batteries have been used in standalone 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. Trojan’s Renewable Energy (RE) Series is a line of technologically advanced lead-acid deep cycle batteries, optimized for renewable energy applications such as solar PV, small wind, and micro hydro. They have heavier duty separators and plates designed for longer life and their warranty has been extended to two years free replacement and 60 months additional pro-rated on the L16s and 36 months pro-rated on the T-105.
This series of deep cycle, lead-acid batteries from Trojan are optimized for micro-grid, solar, small wind, and other renewable energy uses. Designed for extended lifespan, the Premium line has a full two-year warranty, and a prorated for up to five years.
Trojan Premium line of batteries are made with a 10-year battery life in mind. They feature Alpha Plus Paste with T2 Technology, which considerably improves the porosity of the active material resulting in improved performance over longer periods of time; combined with Trojan’s DuraGrid design it increased the overall life cycle of the battery.
The case of of all the Trojan Premium batteries use their branded Polyon container which is a rugged protection against difficult environments and prevents potential acid leaks.
Providing increased lifespan, Trojan’s Smart Carbon technology is now featured in both the Premium and Industrial lines, improving partial state of charge (PSOC) performance and longevity alike. The specially designed formula of Smart Carbon enhances charge acceptance and efficiency by increasing the electrochemically active surface area of the battery. This is particularly beneficial (and efficient) when batteries are not regularly charged to full capacity.

I have contacted owner for Shipping Costs from Canada to USA, but $160 Cdn = $112 US dollars so this is a very good deal.
