Trojan Battery Company
12V, 77AH Deep Cycle Gel Battery
24-GEL

Trojan's deep-cycle gel batteries are sealed, maintenance-free batteries that deliver superior power in demanding renewable energy applications. Engineered for rugged durability, outstanding performance and long battery life, Trojan's deep-cycle gel batteries feature a number of important design characteristics that provide significant advantages over competing gel products. The gelled electrolyte is a proprietary formulation containing sulfuric acid, fumed silica, pure demineralized, deionized water and a phosphoric acid additive. This exclusive formulation produces a homogenous gel that delivers consistent performance and dramatically long cycle life. The heavy-duty grids lock active material onto the grid network to efficiently deliver more concentrated energy to the terminals. Premium grade, double-insulated separators allow maximum charge flow between the plates for optimum performance.

Gel Battery Cycle Life




The most important characteristic to consider when purchasing a deep-cycle battery for a renewable energy application is cycle life. This is usually measured as the number of discharge/charge cycles the battery can provide before its capacity drops to a specified percentage of its rated capacity (i.e. 50%). Batteries from different manufacturers may have the same capacity and energy content and be similar in weight, but design, materials, process, experience and quality control have a big influence on how long the battery will cycle. When comparing two batteries of equal Ah capacity and cost, a battery capable of 1,000 cycles is effectively half the total life cost of one that is only capable of 500 cycles.
