Bosch Deep Cycle Marine (DCM) Battery Range
Engineered for demanding marine power requirements, the Bosch Deep Cycle Marine (DCM) range is purpose-built for heavy-duty cycling applications. Delivering 25% longer service life at 50% Depth of Discharge compared to the HCM range, the DCM series combines substantial engine-starting cranking amperage with exceptional reserve capacity to keep all your onboard electrical accessories running smoothly for longer. Constructed with thicker, fibreglass-reinforced plates, a robust grid alloy, and heavy-duty separators, it is designed to withstand the stress of repeated cycling and harsh marine vibrations.
Ideal for boat owners & operators who require:
- ✓ Heavy-duty deep cycling capability with 25% longer service life at 50% discharge vs HCM
- ✓ Superior reserve capacity for high electrical loads alongside dependable engine-starting power
- ✓ Thicker, fibreglass-reinforced plates and heavy-duty separators for extreme vibration resilience
Deep Cycle Marine Highlights
Extended Heavy-Duty Cycling
- • Engineered specifically for severe, repeated deep discharge and recharge duties
- • Delivers 25% longer cycle life at 50% discharge rate compared to standard HCM units
- • High reserve capacity powers refrigeration, winches, sounders, and house electronics
Fibreglass Reinforced Plates
- • Long-lasting full-frame grid design features thicker, fibreglass-reinforced plates
- • High-density active material maintains structural integrity and electrical conductivity
- • Prevents active material shedding under repeated heavy cyclic loading
Enhanced Stress & Vibration Resistance
- • Specialised grid alloy promotes resilience against cyclic degradation and heat
- • Heavy-duty cell separators isolate plates against intense wave pounding and vibrations
- • Tough outer casing guards against physical impact and harsh marine environments
Starting Cranking & Dual Terminals
- • Retains sufficient Cold Cranking Amps (CCA) to reliably start outboard/inboard engines
- • Dual-fit terminal setup simplifies connection for starter cables and auxiliary wiring
- • Versatile for standalone dual-purpose use or dedicated deep-cycle marine banks
