Battery - 12V/90Ah Gel Deep Cycle Batt.

Reliable and maintenance-free GEL battery for boats, campers, and off-grid energy systems.

The Victron 12V/90Ah Gel Deep Cycle Battery is a robust deep-cycle battery designed for installations where the battery is frequently charged and discharged. With VRLA GEL technology, the electrolyte is bound in a gel, providing high reliability, low self-discharge, and a long lifespan.

This type of battery is ideal for solar power systems, boats, motorhomes, and backup power, where stable energy storage and many charging cycles are important. GEL batteries are particularly suitable for deep discharges and can therefore be used in installations with higher energy consumption.

⚡ Advantages

• 90Ah capacity at 12V

• Deep-cycle design for many charging cycles

• Maintenance-free VRLA GEL battery

• Low self-discharge during storage

• Tolerates deeper discharges than many traditional lead-acid batteries

• Robust construction for marine environments

GEL batteries generally have a longer lifespan and better cyclic durability than many AGM batteries, especially with repeated deep discharges.

⛵ Suitable for

• Sailboats and motorboats

• Motorhomes and vans

• Off-grid solar power systems

• Backup power and energy storage

📊 Specifications

Dimensions and weight are typically around 350 × 167 × 183 mm and approx. 26 kg depending on the model version.

🔋 Advantages of GEL batteries

GEL batteries use a gel-based electrolyte instead of liquid acid:

• No risk of acid spills

• Low self-discharge during storage

• High resistance to vibrations

• Suitable for deep discharges

💡 Tip from SejlStrøm:
A 90Ah GEL battery is typically used in boats with 200-400 W solar panels and an MPPT regulator, where the battery delivers stable power for lights, instruments, autopilots, and smaller refrigerators.
