The Victron Energy AGM Super Cycle 12V 170Ah battery is a deep-cycle lead-acid battery built for applications where repeated deep discharges are the norm rather than the exception. It suits solar storage, marine and off-grid systems where a standard AGM unit would wear out under regular deep cycling. M8 threaded insert terminals give a secure, bolt-down connection for professional installations.

Key features

• Capacity, 12V nominal voltage with 170Ah capacity.
• Super Cycle chemistry, tolerates deeper and more frequent discharge cycles than standard AGM batteries.
• Terminals, M8 threaded inserts for bolt-down cable connections.
• Construction, valve-regulated, sealed, maintenance-free, suitable for enclosed spaces.
• Compatibility, works with Victron Energy chargers, inverter/chargers and battery monitors when set to the correct AGM charge profile.
• Weight, 45 kg, so plan for handling and structural support.

Product overview

Standard AGM batteries have a limited number of deep discharge cycles before capacity drops off. The Super Cycle range uses a modified plate design and electrolyte formulation that allows regular discharges down to 20% state of charge without the same rate of capacity loss, making it a practical option for off-grid systems cycled daily.

The M8 threaded inserts accept bolts directly, giving a consistent, torque-controlled connection that holds through vibration, which matters on boats and vehicles. The sealed AGM construction means no acid spillage and no topping up, and it can be installed in any orientation except inverted.

Pair it with a Victron MPPT controller or MultiPlus inverter/charger set to the AGM Super Cycle profile. A Victron BMV monitor is recommended to track state of charge, since lead-acid batteries need careful management to reach their rated cycle count.

Applications

Off-grid solar storage with daily charge and discharge cycles, marine house battery banks, motorhome and vehicle leisure installations, and backup power systems needing reliable deep-cycle performance.

Installation notes

At 45 kg this battery needs two people or mechanical assistance to move safely. M8 bolts and cable lugs are required for the terminals and are not supplied. Set charging equipment to the correct AGM Super Cycle parameters before commissioning, and follow local electrical regulations when working with large lead-acid batteries.
