Discover D27A & D31A Deep Cycle AGM Batteries:

Discover® VRLA AGM Deep Cycle batteries are built for mobile applications that undergo frequent vibration and require large power demands such as RV, Caravan, Marine and 4WD Dual battery systems. The batteries are safe, non spillable, maintenance-free and are trusted by boat and recreational vehicle owners.

The design has seen improvements in the battery case, battery plates and intercell welding over traditional ABS case designs. Most deep cycle VRLA batteries are constructed using an ABS case. Discover D27 and D31 batteries use a PP (Polypropylene) case, which is the same material used to build automotive batteries, hence has superior mechanical, thermal and electrical properties. The PP case also offers very good resistance to heat distortion and a high resistance to chemicals making it suitable for under the bonnet applications.
