xVictron Energy 12V 90Ah AGM Deep Cycle Battery
The Victron Energy 12V 90Ah AGM Deep Cycle Battery is a sealed, maintenance-free lead-acid battery rated at C20 capacity. It is designed for cyclic applications in solar, off-grid, marine and backup power systems where reliable deep discharge performance is required.
Key Features
- 90Ah capacity rated at C20 discharge rate, suitable for deep cycle use.
- Absorbed Glass Mat (AGM) construction: sealed, spill-proof and maintenance-free.
- 12V nominal voltage, compatible with standard 12V system architectures.
- Low self-discharge rate, making it suitable for seasonal or standby applications.
- Recombinant technology minimises gas emission during normal operation, allowing installation in enclosed spaces.
- Heavy-duty plates designed to withstand repeated deep discharge and recharge cycles.
- Weight of 22.5 kg reflects the high lead content associated with genuine deep cycle construction.
Product Overview
AGM deep cycle batteries differ from standard starter batteries in plate thickness and active material density. Victron's deep cycle AGM range uses thicker plates and a higher paste density to deliver sustained energy over a longer discharge period, rather than a short burst of high current. This makes them appropriate for solar storage, inverter backup and off-grid applications where the battery is regularly discharged to 50% or below.
The AGM separator holds the electrolyte in suspension against the plates, eliminating free liquid. This means the battery can be mounted in any orientation except inverted, and does not require ventilation for acid fumes under normal operating conditions. It is, however, still a lead-acid chemistry and should be charged with a compatible multi-stage charger set to AGM parameters. Overcharging or undercharging will shorten service life.
At 22.5 kg, this battery is at the upper end of what a single person can safely handle. Plan installation access and fixing arrangements accordingly. For larger capacity requirements, multiple units can be connected in parallel (same voltage) or series (to increase voltage) provided all batteries are of the same type, age and state of charge at the time of connection.

Installation Notes
This battery should be installed and commissioned by a qualified electrician or competent person familiar with lead-acid battery systems. Ensure the charger or charge controller is configured for AGM chemistry with appropriate absorption and float voltages. Batteries must be secured against movement, particularly in marine or vehicle installations. Do not install in a fully sealed, unventilated enclosure without confirming the space meets minimum safety requirements for lead-acid batteries. Dispose of used batteries through an approved recycling scheme in accordance with UK WEEE and battery regulations.
