The Victron Energy AGM Super Cycle 12V 15Ah battery is a deep-cycle lead-acid battery built for applications where regular, deep discharge is unavoidable. Solar storage, marine and off-grid setups all put standard AGM batteries under strain when cycled daily. This Super Cycle version is designed to hold up better under that repeated use. M5 threaded insert terminals give a secure, vibration-resistant connection.

Key features of this Victron AGM battery

• Voltage and capacity, 12V nominal, 15Ah, suited to compact off-grid and backup power installations.
• Cycle tolerance, AGM Super Cycle construction tolerates deeper and more frequent discharge cycles than standard AGM batteries.
• Terminals, M5 threaded inserts allow a firm, bolt-down connection that resists loosening under vibration.
• Build, sealed, valve-regulated (VRLA) design, maintenance-free, mountable in any orientation except inverted.
• Weight, 4.1 kg, practical for portable or space-constrained installs.
• Compatibility, works with Victron charge controllers and inverter-chargers that support AGM battery profiles.

Why the design matters

Standard AGM batteries lose capacity quickly once they're regularly discharged to 50% or below. The Super Cycle range uses a modified plate design and electrolyte formulation aimed at extending cycle life under that kind of daily use, which suits solar systems where cycling isn't the exception, it's the routine. The M5 threaded inserts also matter in practice: a bolt goes directly into the terminal post, giving consistent torque and a joint that doesn't work loose, which counts for something on a boat or in a moving vehicle.

Applications

At 12V and 15Ah this is a smaller-format battery: a dedicated control power supply, a lighting circuit battery, or one unit in a parallel bank where space per unit is tight. Typical uses include marine auxiliary power, caravan and motorhome leisure supply, UPS and backup power for telecoms or alarms, and control power within larger inverter installations. Use with Victron MPPT charge controllers and MultiPlus inverter-chargers on the AGM or AGM Super Cycle charge profile.

Installation notes

Fit and wire this battery through a qualified electrician or experienced installer. Set the charge source to an AGM or AGM Super Cycle profile to avoid overcharging. Mount in any orientation except fully inverted. When wiring multiple units in parallel, use equal cable length and cross-section for balanced charging, and don't mix batteries of different age, capacity or chemistry in one bank.
