Wherever machines need to work reliably over many hours a day, this battery provides the necessary energy.

Superior deep-cycle technology

Trojan batteries have set the industry standard for genuine deep-cycle performance for decades. The exclusive T2 Technology® with Alpha Plus® paste formulation delivers maximum electrochemical efficiency and slows the ageing process of the active mass. DuraGrid™ grid architecture provides outstanding corrosion resistance and improved current conduction, resulting in increased overall performance and longer battery life.

Built for durability and efficiency

The construction of the J305E-AC is designed for maximum robustness and simple maintenance. The impact-resistant polypropylene casing withstands the rigours of daily use. The low-maintenance design only requires regular checking and, if necessary, refilling with distilled water to maintain the full capacity and service life of the battery over many years. This makes it a highly economical solution for professional fleet operators.

FAQs about the Trojan J305E-AC Deep-Cycle Battery

What does "deep cycle" mean?

"Deep cycle" means that the battery is designed to regularly provide a large proportion (up to 80%) of its stored energy and then be fully recharged again, without rapidly losing capacity. This is essential for supply applications, as opposed to starter batteries.

What does "low maintenance" mean?

As a low-maintenance wet-cell battery, the fluid level (electrolyte) in the cells must be checked regularly and topped up only with distilled water as necessary. Proper maintenance is essential for achieving the maximum service life.

Which charger do I need for this battery?

You need a high-quality, multi-stage charger with a dedicated charge profile for lead-acid wet-cell batteries. The charging voltage and current must comply with Trojan’s specifications to ensure complete and gentle charging and to maximise service life.

How are multiple batteries connected to form a system?

For the usual 36V or 48V systems in golf carts or work platforms, several of these 6V batteries are connected in series. It is vital that only batteries of the same type, age and condition are connected together in order to ensure an even load.

How must this lead-acid battery be disposed of?

Lead-acid batteries contain environmentally hazardous substances and must not be disposed of with household waste. You can return your old battery free of charge at any retailer selling new batteries or at municipal recycling centres to ensure environmentally sound disposal.
