Victron 12V 220Ah AGM Deep Cycle Battery | BAT412201084

The Victron Energy 12V 220Ah AGM Deep Cycle Battery is a sealed, maintenance-free lead-acid battery rated at C20 capacity. It suits cyclic applications in solar, off-grid, marine and backup power systems where deep discharge performance matters.

Key features

• Capacity, 220Ah rated at the C20 discharge rate, the standard reference for solar and off-grid sizing.
• Construction, Absorbent Glass Mat (AGM) design with no free electrolyte, making it spill-proof for confined or enclosed spaces.
• Sealed design, valve-regulated, no water topping needed, minimal gassing under normal charging.
• Voltage, 12V nominal, compatible with standard 12V charge controllers, inverters and battery management systems.
• Weight, 62.5 kg, reflecting the lead content used for genuine deep cycle performance.
• Brand compatibility, works with Victron charge controllers, inverters and battery monitors when configured with Victron's recommended AGM charge profile.

Product overview

AGM deep cycle batteries use thicker plates and denser active material than standard standby batteries, letting them withstand repeated deep discharge and recharge cycles. The C20 rating means the 220Ah figure is measured over a 20-hour discharge period. The AGM separator holds electrolyte against the plates rather than letting it pool freely, which improves charge acceptance and reduces internal resistance compared with flooded equivalents. It can be installed in any orientation except inverted, with no acid spillage risk during transport or installation.

Applications

Suited to solar energy storage in off-grid and hybrid systems with MPPT or PWM charge controllers, marine house battery banks, motorhome and campervan leisure installations, UPS and backup power for telecoms or security equipment, and remote site power. It can also be wired into multi-battery 12V, 24V or 48V banks in series or parallel.

Installation notes

At 62.5 kg, two people or handling equipment are needed for safe positioning. Use correctly rated cable, fusing and terminal hardware, and follow Victron's published AGM charge profile to avoid undercharging or overcharging.
