Deep Cycle Batteries: The Heart of Your Off-Grid Power System.

Unlike a standard car battery designed for a quick burst of starting power, a Deep Cycle Battery is the marathon runner of your electrical system. Often called a "house battery," it is specifically engineered to provide a steady, reliable flow of current over a long period. At RV World, we supply a range of high-quality deep cycle solutions from trusted brands like Enerdrive, Artemis, Valen, and Camec, ensuring your lights, fridge, and water pump keep running through every Kiwi adventure.

Understanding Battery Chemistry: Which Style Suits You?

While all batteries in this category are built for cycling, the internal construction varies significantly. Choosing the right "job-specific" battery is key to your system's longevity:

• AGM (Absorbent Glass Mat): The most popular choice for modern NZ caravans. AGM batteries are completely sealed, maintenance-free, and don't require external venting. They handle vibrations exceptionally well and can be installed in diverse orientations.
• Lithium (LiFePO4): The gold standard for performance. Lithium batteries are up to 50% lighter than AGM, charge significantly faster, and offer nearly 100% usable capacity. While the upfront cost is higher, their massive cycle life (often 3,000+) makes them the most cost-effective long-term investment for frequent travellers.

Usable Capacity and Battery Health

When sizing your battery bank, it is vital to consider the Depth of Discharge (DoD). To protect your investment and ensure a long working life, traditional Lead-Acid and AGM batteries should generally not be discharged below 50% of their total capacity. In contrast, Lithium batteries can be safely discharged down to 10-20%, giving you nearly double the "usable" power for the same Amp Hour (Ah) rating.

Expert Support for Your 12V Setup

Selecting the right battery depends on your power usage, charging system (solar or alternator), and available space. Whether you are looking for a slimline AGM to fit under a seat or a high-capacity Enerdrive B-TEC Lithium system for total independence, our team is here to help.
