We now stock Varta AGM Deep Cycle Batteries. We also stock Deka, Sonnenschein, Federal, Alco and other Deep Cycle Brands, and some others are available on request if customers have a preference for them.

The main considerations in RV/Motorhomes are often size, price, capacity (Amp-Hours) and whether to choose a Sealed battery (GEL/AGM) or a regular Wet Lead Acid. Our Deep Cycle Help & FAQ may help.

We don't mind getting our hands dirty taking a look at and testing your set up if you can travel to us, or otherwise we can give advice by phone or email. Good advice and our low pricing on Batteries, Cabling, Chargers, Solar and accessories will save you money either way! Easy parking at our Stores.
