HVT‑70ZZD AGM Dual‑Purpose Battery – Ultra High‑Performance DryCell Power for 4WD, Marine, Caravan & Commercial Use

The HVT‑70ZZD is one of Australia’s most powerful and versatile AGM batteries, engineered for drivers, adventurers, marine users, commercial operators and off‑grid travellers who demand premium reliability, exceptional performance, and long‑lasting durability. Built using advanced DryCell VRLA AGM technology, the HVT‑70ZZD delivers an impressive 780CCA of strong cranking power while functioning as a true dual‑purpose battery — capable of both starting engines and powering deep‑cycle accessories.

Designed for enthusiasts who expect more from their battery system, the HVT‑70ZZD stands out as an ultra high‑performance powerhouse, excelling in 4WD touring, marine environments, caravans, camper trailers, motorhomes, trucks, buses, and emergency backup systems. Its fully sealed construction allows safe installation in enclosed spaces, while its fire‑retardant ABS casing ensures maximum safety in demanding conditions.

Unlike traditional AGM batteries, the HVT‑70ZZD is engineered to operate in any position — upright, sideways, or upside down — making it ideal for tight compartments, marine hulls, under‑seat installations, and custom setups. This flexibility is paired with a Thermal Management System that prevents overheating, significantly extending battery life in Australia’s hot climate.

The HVT‑70ZZD is also under‑bonnet rated, a rare advantage among AGM batteries. This means it can be safely installed in cars, 4WDs, trucks, buses, motorhomes, commercial equipment, and performance vehicles without risk of thermal damage. Its vibration‑resistant construction makes it perfect for corrugated roads, off‑road tracks, marine chop, and industrial machinery.

As a deep‑cycle performer, the HVT‑70ZZD uses a specialised alloy that allows deeper discharge without harming the internal plates. This dramatically increases cycle life, making it ideal for powering fridges, lights, pumps, inverters, communication equipment, and off‑grid camping setups. Whether you’re running a dual‑battery system, a marine electrical network, or a caravan power system, the HVT‑70ZZD delivers consistent, dependable energy.

The battery emits no gases, making it safe for cabins, caravans, boats, and indoor environments. Its sealed VRLA design eliminates maintenance, leaks, and corrosion, ensuring long‑term reliability with minimal upkeep.

Developed in Australia and engineered to meet the demands of modern performance vehicles and equipment, the HVT‑70ZZD is part of the highly successful SSB HVT DryCell AGM Series — a range so effective that competitors have attempted to replicate it with limited success. When reliability, safety, and performance matter, the HVT‑70ZZD stands out as a top‑tier choice for both recreational and commercial users.

Warranty

The HVT‑70ZZD includes a warranty of up to 36 months, depending on battery type and usage conditions (domestic vs commercial). This provides strong long‑term protection and confidence for all applications.
