New Battery Design Enhances Transport and Installation

Santa Fe Springs, Calif., Sept. 12, 2012 – Trojan Battery Co., the world's leading manufacturer of deep-cycle batteries, is now shipping its new 2-volt Industrial batteries. The latest deep-cycle battery additions for renewable energy and backup power applications include two new sizes, and feature a unique design making transport and installation of the batteries easier for a variety of solar applications.

"As installations of off-grid solar applications for applications such as off-grid telecom networks, micro grids, island and rural electrification and backup power increase worldwide, so will the need for reliable, deep-cycle batteries for energy storage," said Bryan Godber, Trojan executive vice president of renewable energy. "To address this demand, Trojan continues to put its more than 85 years of battery expertise to work developing innovative battery technologies to effectively meet the growing need for reliable access to power around the world."

The new Industrial batteries include the IND27-2V model featuring a 1457Ah capacity at C20, and the IND33-2V version that offers a 1794 Ah capacity at C20. Trojan also includes a 4/O cable and hardware with each of its Industrial batteries for series connections. These Industrial battery cables provide the link between the batteries, equipment and charging system.

To enhance safety, the new Industrial batteries also feature customizable terminal protectors which increase protection against shock or short circuiting and terminal corrosion. The protectors feature perforated cut-outs along the sides and top enabling them to be customized to fit the specific cable configuration required by customer.

The Industrial line supports large daily loads where the batteries are cycled regularly in a range of photovoltaic systems, including off-grid and unstable grid situations. Specifically designed for deep-cycle use, Trojan's Industrial line is optimized for deep discharge and recharge cycles characteristic of renewable energy systems. It is engineered for high-energy requirements delivering 1,500 cycles at 80 percent depth-of-discharge, and features advanced battery technologies that provide optimum performance. The Industrial line features the following unique design elements.

Rugged Construction & Intelligent Design
The 2-volt cells of the new Industrial line additions are assembled in a rugged polypropylene housing designed to protect the internal plates from damage that may occur during transport and installation. The cells are enclosed in a larger polyethylene outer case that protects against damage caused by harsh environmental conditions such as moisture and dirt buildup, as well as safeguards against potential acid leaks. For added protection the thick-walled case features a lattice-design that reinforces the outer case's structural integrity. This dual container construction provides added protection against extreme temperatures.

Trojan Advanced Battery Technologies
Engineered for high-energy requirements, the Industrial line features the following advanced battery technologies that provide optimum performance.

Alpha Plus® Paste with T2 Technology™ & DuraGrid™ Design
Trojan's Alpha Plus Paste is a proprietary, high-density paste formulation precisely engineered to deliver outstanding battery performance. This high-density paste optimizes porosity development in the active material utilizing the active material more effectively resulting in sustained battery performance over a longer period of time. Trojan's T2 Technology features a patent-pending T2 metal agent which is incorporated into Trojan's Alpha Plus Paste further strengthening the electrochemical processing capabilities of the paste. Together the Alpha Plus Paste with T2 Technology increase both sustained capacity and total overall ampere-hours resulting in more operating power.

Combined with the innovative DuraGrid design, which provides a thick grid structure that resists corrosion, the Alpha Plus Paste with T2 technology increases overall battery life. The Industrial line's low-profile grid configuration also optimizes current flow throughout the grid network and maximizes the amount of electrolyte that can be added resulting in longer intervals between watering.

Reinforced Protection Wrap
Trojan's Industrial batteries are engineered with a robust positive plate construction that enhances overall performance. Trojan's DuraGrid technology combined with Alpha Plus paste securely locks the active materials to the grid creating an exceptionally strong positive plate. The Industrial line includes a five component wrapping and insulating system comprised of a stranded vertical slyver, which are filaments of glass wrapped around the positive plate's active mass surface, a 20 mil backing bat and a secondary 20 mil horizontal compression mat. The entire mat is wrapped with edge-protecting Koroseal that is heat bonded as well as bonded to the plastic boot to protect the bottom of the plate and to keep the Koroseal in place. The advanced plate construction protects against shedding and assures the electrochemical performance of the battery's active materials.

Maxguard® XL Separator
Exclusively available in Trojan's Industrial and Premium line batteries is the Maxguard XL separator. Featuring a wide-channel design, the Maxguard XL separator increases acid flow for optimum battery performance. Thirty percent thicker than our standard flooded battery separators, the Maxguard XL provides even greater resistance to stratification which is a typical mode of failure in batteries used in renewable energy systems.
