The Delkor HDC27 is a 100Ah 12V calcium deep cycle battery engineered for sustained auxiliary power in caravans, camper trailers, and 4WD setups across Australia's toughest conditions. Built on advanced calcium-alloy plate technology, it delivers a cold cranking amps (CCA) rating of 750A alongside a reserve capacity of 165 minutes — meaning more hours of reliable power for your fridge, lighting, and camp accessories without the need to constantly run your vehicle. The maintenance-free, sealed construction eliminates the need for water top-ups and virtually eliminates self-discharge during extended storage between trips.

The HDC27 is purpose-built for Australian caravanners, RV travellers, and 4WD adventurers who demand a dependable house battery that handles repeated charge-discharge cycles on long outback runs or coastal road trips. Whether you're powering a 12V compressor fridge on a week-long Gibb River Road crossing, running camp lighting at a free campsite in the high country, or supporting a solar charging system on your motorhome, the HDC27's deep cycle capability and robust Group 27 footprint make it a drop-in fit for most caravan battery boxes and dual-battery tray systems. Its calcium construction also means superior corrosion resistance in the marine, off-road, and high-vibration environments common to Australian adventure travel.
