Power-Sonic deep cycle PDC range is purpose built for those applications which require regular and consistent cycling (charge and dis-charge). Commonly called deep cycling the oversized negative plates and a specialised paste formulation of the PDC can provide constant power for longer periods of time without shortening the life of the battery.

Typical applications include: weekend or holiday homes with large electrical loads, medium solar systems for industrial applications, small solar and wind-driven power plants, offshore buoys, yachts, measurement stations.

They feature:

• Absorbent Glass Mat (AGM) technology for superior performance
• Valve regulated, spill proof construction for safe operation in any position
• Oversize negative plates and a specialized paste formulation for true deep cycle performance.
• Special additives in the paste ensure superior performance in deep discharge situations.
• Power/volume ratio yielding unrivalled energy density
• Rugged impact resistant ABS case and cover (UL94-HB)
• Approved for transport by air. D.O.T., I.A.T.A., F.A.A. and C.A.B. certified
• L. certified

*Due to the self-discharge characteristics of this type of battery, it is imperative that they be charged within 6 months of storage, otherwise permanent loss of capacity might occur as a result of sulfation.
