Victron 12V 220Ah Gel Deep Cycle Battery | BAT412201104

The Victron Energy 12V 220Ah Gel Deep Cycle Battery is a sealed, maintenance-free lead-acid battery for cyclic and standby use in solar, off-grid and marine systems. Capacity is rated at C20, giving a predictable discharge curve when sizing a battery bank.

Key features

• Capacity, 220Ah rated at C20
• Electrolyte, gel construction, no free liquid, spill-proof
• Cycling, deep cycle design suited to daily solar charge and discharge
• Construction, sealed, valve-regulated (VRLA), no topping up required
• Voltage, 12V nominal, can be wired in series or parallel for 24V or 48V banks
• Compatibility, works with Victron MPPT charge controllers and MultiPlus/Quattro inverter-chargers when set to a gel charge profile

Product overview

Gel batteries use a silica-based gelled electrolyte instead of liquid acid. This immobilises the electrolyte, reducing stratification and self-discharge compared with flooded lead-acid, and allows mounting in orientations other than upright. For solar installations that sit unused for periods, the lower self-discharge is useful in practice.

The deep cycle rating means the battery tolerates regular discharge to a significant depth of discharge, unlike standby batteries built for shallow float cycling. Correct charge voltage matters: overcharging is the main cause of premature gel battery failure, so the charge source needs a gel-specific profile rather than one set for AGM or flooded types.

At 62.5 kg this is a heavy unit. Plan for structural support, cable routing and safe handling, and torque terminal connections to the manufacturer's specification.

Applications

Suited to off-grid solar storage in residential, agricultural and remote installations, marine house battery banks, motorhome and leisure vehicle power systems, and backup power for telecoms, security or industrial equipment. Multiple 12V units can be wired in series for 24V or 48V banks.
