Description
xVictron Energy 12V 15Ah AGM Super Cycle Battery (M5 Terminals)
The Victron Energy AGM Super Cycle 12V 15Ah battery is a deep-cycle lead-acid battery designed for applications where regular, deep discharge is unavoidable. It is built for solar storage, marine, and off-grid use where a standard AGM battery would degrade quickly under repeated deep cycling. The M5 threaded insert terminals provide a secure, vibration-resistant connection.
Key Features
- 12V nominal voltage with 15Ah capacity, suitable for compact off-grid and backup power installations.
- AGM Super Cycle construction tolerates deeper and more frequent discharge cycles than standard AGM batteries.
- M5 threaded insert terminals allow a firm, bolt-down connection that resists loosening under vibration.
- Sealed, valve-regulated (VRLA) design requires no maintenance and can be mounted in any orientation except inverted.
- Victron Energy manufacture, compatible with Victron charge controllers and inverter-chargers that support AGM battery profiles.
- Weighs 4.1 kg, making it practical for portable and space-constrained installations.
Product Overview
Standard AGM batteries are rated for a limited number of deep discharge cycles before capacity degrades significantly. The Super Cycle range addresses this by using a modified plate design and electrolyte formulation that extends cycle life when the battery is regularly discharged to 50% or below. This makes it a more practical choice for solar systems where daily cycling is the norm rather than the exception.
The M5 threaded inserts are a practical detail that matters in real installations. Unlike standard lead terminals, threaded inserts accept a bolt directly into the terminal post, giving a consistent torque and a connection that does not work loose over time. This is particularly relevant in mobile or marine environments where vibration is a factor.
At 12V and 15Ah, this battery is suited to smaller systems: a single unit can serve as a dedicated control power supply, a lighting circuit battery, or part of a parallel bank where space per unit is limited. It is fully compatible with Victron MPPT charge controllers and MultiPlus inverter-chargers when the AGM or AGM Super Cycle charge profile is selected.

Installation Notes
This battery should be installed and wired by a qualified electrician or experienced installer. Ensure the charge source (solar charger, inverter-charger, or mains charger) is set to an AGM or AGM Super Cycle charge profile to avoid overcharging. The battery can be mounted in any orientation except fully inverted. When connecting multiple units in parallel, use cables of equal length and cross-section to ensure balanced charging and discharging. Do not mix this battery with batteries of a different age, capacity, or chemistry in the same bank.
