Update your group 27 deep cycle battery with the best

If it is time to update or replace your group 27 deep cycle battery, then a battery from Deep Cycle Systems is your best choice.

Our group 27 deep cycle batteries provide extra power, reliability and durability with the added benefit of no maintenance required.

A group 27 deep cycle battery will typically have external dimensions of 306mm (length) x 174mm (width) x 237 mm (height). The group 27 classification is determined by the standards set by the Battery Council International, or BCI.  While this classification does not determine the Amp Hours (AH) rating for the batteries, there is usually a correlation between case size and AH rating. In most situations, the larger the battery case size is, the more capacity the battery will usually have.

If you are looking for group 27 deep cycle battery , then our DCS 100 Ah battery could be the perfect choice for you. It  has external dimensions of 328mm (length) x 171mm (width) x 215 mm (height) which means that it can fit into most spaces occupied by a traditional group 27 deep cycle battery. You can therefore upgrade your current AGM, Gel or lead acid battery to lithium ion technology that can last up to 5000 cycles. Our DCS 100Ah battery comes with the additional benefit of six times the battery life and weighs less than half that of a conventional lead-acid battery.

Our range of high capacity 12 volt deep cycle batteries are all backed by a 3 year replacement warranty.
