Vision Lead-acid battery 6FM90DX Cyclic with 12V and 90Ah

The Vision 6FM90DX is a high-performance, cycle-resistant and valve-regulated lead-acid battery (VRLA) with a nominal voltage of 12 volts and a capacity of 90 Ah. Designed for demanding cyclic applications, this battery combines maintenance-free AGM technology with a particularly robust design. It offers a reliable and long-lasting energy solution for areas where repeated charging and discharging is required, such as in solar technology, mobile applications or electric vehicles.

Highlights at a glance

• High cycle stability: Developed for demanding cyclic operation and a long service life even with deep discharges.
• High capacity: 90 Ah at 12 V for a long-lasting and reliable power supply for demanding consumers.
• Maintenance-free AGM technology: The advanced AGM (Absorbent Glass Mat) technology ensures leak-proof and maintenance-free operation.
• Low self-discharge: With only around 3% self-discharge per month, the battery is immediately ready for use even if it is not used for a longer period of time.
• Flexible mounting: Operation is possible in all positions, with the exception of permanent overhead use.
• Robust construction: The robust ABS plastic housing reliably protects the battery from mechanical impacts and vibrations.

Reliable energy for demanding cycles

The Vision 6FM90DX has been specially optimised for cyclic use. It delivers a nominal capacity of 90 Ah with a 20-hour discharge (C20). Its particular strength lies in its ability to be repeatedly deep discharged and recharged without significant loss of capacity. This makes it the ideal choice for solar systems, electric vehicles, cleaning machines and other mobile power supplies that require constant and reliable performance.

Advanced technology for maximum longevity

Thanks to the VRLA technology (Valve Regulated Lead Acid) in combination with the AGM system, in which the electrolyte is bound in a glass fibre fleece, the 6FM90DX is completely sealed and maintenance-free. This not only prevents leakage, but also enables efficient gas recombination within the cell. The battery is characterised by a low internal resistance, which allows a high current draw. The low self-discharge ensures that the stored energy is retained over long periods of time, which is particularly advantageous for seasonally used appliances.

Characteristics

FAQs about the Vision 6FM90DX lead-acid battery

For which applications is the Vision 6FM90DX suitable?

This battery is specially designed for cyclic applications and is ideal for:

• Solar and photovoltaic off-grid systems
• Motorhomes, caravans and boats
• Electric wheelchairs and scooters
• Cleaning machines and automated guided vehicles (AGV)
• Uninterruptible power supplies (UPS) with high cycle requirements

What does the term "cyclic" mean?

Cycle-proof means that the battery is designed to be frequently and deeply discharged and then fully recharged. In contrast to a conventional starter battery, which is designed for short, high current surges, a cycle-proof battery retains its capacity over many of these charge and discharge cycles.

Is the battery completely maintenance-free?

Yes, thanks to the sealed AGM technology, the battery is completely maintenance-free. No topping up with distilled water is required and it is protected against leakage.

How should the battery be charged to maximise its service life?

To maximise service life, we recommend using a high-quality charger with an IUoU charging characteristic that is suitable for AGM batteries. The charging voltage should be between 14.4 V and 15.0 V in cyclic operation at 20 °C. The maximum charging current should not exceed 27 A.

Can I connect several of these batteries together?

Yes, you can connect several Vision 6FM90DX batteries in series to increase the voltage (e.g. two for a 24 V system) or in parallel to increase the capacity. Please ensure that you only connect batteries of the same type, age and state of charge to ensure optimum performance and service life.

What storage conditions and temperature ranges apply?

• Charging: 0 °C to +40 °C
• Discharging: −20 °C to +50 °C
• Storage (fully charged): −20 °C to +40 °C

Always store the battery in a fully charged state in a cool, dry place. Due to the low self-discharge rate, recharging is only necessary every six months during longer storage periods.
