Victron Energy 12V 8Ah AGM Deep Cycle Battery

The Victron Energy 12V 8Ah AGM Deep Cycle Battery is a sealed, maintenance-free lead-acid battery rated at C20 capacity. It is suited to small off-grid systems, UPS applications, and any installation where a compact, reliable deep cycle battery is required. The AGM (Absorbent Glass Mat) construction makes it spill-proof and safe for use in enclosed spaces.

Key Features

• 12V nominal voltage with 8Ah capacity rated at C20 discharge rate.
• AGM construction: sealed, valve-regulated, and maintenance-free with no electrolyte topping required.
• Deep cycle design allows repeated charge and discharge cycles without premature capacity loss.
• Spill-proof and leak-proof construction permits installation in any orientation.
• Compact and lightweight at 2.32 kg, suitable for space-constrained installations.
• Compatible with standard Victron chargers and charge controllers configured for AGM battery chemistry.

Product Overview

AGM batteries use a glass mat separator to hold the electrolyte in place, eliminating free liquid inside the cell. This makes them inherently safer than flooded lead-acid batteries in enclosed or poorly ventilated spaces, and removes the need for periodic water top-ups. The valve-regulated design allows controlled venting of any gases produced during charging, preventing pressure build-up without allowing air ingress.

The C20 rating means the 8Ah capacity is measured over a 20-hour discharge period, which is the standard reference for deep cycle batteries. In practice, discharge at higher rates will reduce available capacity, so this should be factored into system sizing. For small solar systems, backup power supplies, or auxiliary loads, this battery provides a dependable energy reserve in a compact form factor.

Victron AGM Deep Cycle batteries are manufactured to consistent quality standards and are designed to work within the Victron ecosystem. When paired with a Victron MPPT charge controller or battery charger set to the correct AGM charge profile, battery life is maximised and the risk of overcharging is minimised.

Installation Notes

Although this battery is sealed and maintenance-free, it should still be installed in a dry location away from direct heat sources. Use the correct AGM charge profile on any connected charger or charge controller; using a flooded or gel profile may shorten battery life. Ensure terminal connections are correctly torqued and polarity is observed before connecting any load or charger. For integration into a larger solar or backup power system, installation by a qualified electrician is recommended.
