The Victron 12V 165Ah AGM deep cycle battery is a sealed, maintenance-free lead-acid battery built for cyclic use in solar, off-grid and backup power systems. Its 165Ah capacity is rated at the C20 discharge rate, giving installers a predictable energy reserve for repeated deep discharge duty.

Key features of this victron agm battery

• Capacity, 165Ah rated at C20 discharge.
• Construction, Absorbed Glass Mat (AGM), sealed and spill-proof with no free electrolyte.
• Maintenance, no water topping or electrolyte checks required.
• Plate design, optimised for repeated deep charge and discharge cycles.
• Voltage, 12V nominal, suited to series or parallel wiring for 24V or 48V banks.
• Weight, 44.5 kg.

Compatibility

Works with Victron MPPT charge controllers and MultiPlus or Quattro inverter/chargers when the correct AGM charge profile is programmed. Getting the charge voltages right matters: wrong settings are a common cause of early failure in AGM batteries used in cyclic roles.

Applications

• Solar energy storage for off-grid residential and commercial systems.
• Battery banks paired with MultiPlus or Quattro inverter/chargers.
• Marine and leisure installations needing deep cycle capability.
• Backup power systems with regular discharge and recharge cycles.
• Mobile and vehicle-based power systems requiring a sealed, spill-proof battery.
• Telecoms and remote monitoring sites with solar charging.

Installation notes

Fitting should be carried out by a qualified electrician or accredited solar installer. At 44.5 kg, two-person handling or mechanical lifting equipment is recommended. When wiring multiple units into a bank, use equal-length, equal cross-section cabling to every terminal so charge and discharge stay balanced across the battery bank.
