Victron 12V 14Ah AGM Deep Cycle Battery | BAT212120086

The Victron Energy 12V 14Ah AGM Deep Cycle Battery is a sealed, maintenance-free lead-acid battery for cyclic applications that need reliable, repeated discharge. Rated at C20 capacity, it suits off-grid, backup and auxiliary power installations where a compact, spill-proof battery is required.

Key features

• Voltage and capacity, 12V nominal, 14Ah rated at the C20 discharge rate.
• AGM construction, sealed, valve-regulated, maintenance-free with no free electrolyte.
• Deep cycle design, built for repeated charge and discharge cycles.
• Mounting, spill-proof and leak-proof, can be mounted in any orientation.
• Weight, 3.67 kg, suited to portable and space-constrained installs.
• Charger compatibility, works with Victron Energy chargers, inverter/chargers and solar charge controllers set to an AGM profile.

Product overview

AGM construction uses a glass mat separator to hold the electrolyte in place, removing the risk of acid spillage and allowing installation in enclosed spaces or at angles that would be unsafe for a flooded battery. The valve-regulated design means no topping up with distilled water and no venting of hydrogen under normal operating conditions.

The deep cycle rating sets this apart from a standby or starter battery: it can be discharged to a meaningful depth and recharged repeatedly without early capacity loss. For the longest service life, avoid discharging below 50% state of charge and use a charger with an AGM-specific charge profile. Victron's MPPT solar charge controllers and battery chargers include dedicated AGM profiles matching the required absorption and float voltages.

At 14Ah (C20) this is a compact unit, better suited to auxiliary, backup and small off-grid roles than primary storage in larger systems. It pairs well with Victron BMV battery monitors, small inverters, and alarm or UPS applications needing a dependable sealed battery.

Applications

• Small off-grid solar systems and solar lighting
• Auxiliary and backup power for caravans, motorhomes and boats
• UPS and alarm system battery replacement or expansion
• Portable power packs and field equipment
• Victron-based systems needing a compact AGM battery for auxiliary loads

Installation notes

Sealed and maintenance-free, but still install in a ventilated location as a precaution against gas release under fault conditions. Use a charger or charge controller with a correct AGM profile to avoid overcharging, which shortens battery life. Ensure cable connections are correctly rated and fused close to the terminal. Installation by a qualified electrician or competent person is recommended.
