The Delkor M27 Marine & Leisure Battery delivers reliable, deep-cycle performance purpose-built for the demands of Australian caravanning, boating, and off-grid camping. Built to BCI Group 27 standards with a robust 105Ah capacity and a 600 CCA cold cranking rating, this 12V lead-acid battery combines powerful engine-starting grunt with sustained auxiliary power delivery — making it a true dual-purpose workhorse. Its reinforced calcium-calcium grid technology significantly reduces water loss, self-discharge, and internal corrosion, giving you a battery that lasts longer and requires less maintenance across the seasons.

Whether you're running a 12V fridge, lighting, and a water pump in a caravan parked up in the Kimberley, powering accessories on a tinnie out on Australian coastal waters, or keeping your motorhome's auxiliary systems alive on a long outback touring trip, the Delkor M27 is engineered for the job. Its vibration-resistant construction handles the corrugations of unsealed 4WD tracks without complaint, while the low-maintenance sealed design means you spend more time enjoying the outdoors and less time checking fluid levels. Trusted by Australian campers, caravanners, and boaties who need consistent, dependable power far from the nearest auto shop.
