VISION lead-acid battery 6FM45DX with 12V and 50Ah

The Vision 6FM45DX is a robust, cycle-proof lead-acid battery (VRLA) with a nominal voltage of 12 volts and a capacity of 50 ampere hours (at 20h rate). It is specially designed for demanding applications with recurring charging and discharging cycles. Thanks to the AGM technology (Absorbent Glass Mat), this battery provides reliable, leak-proof and long-lasting power. It is the ideal solution for systems that require high cycle stability, deep discharges and long service life, and is excellently suited for both cyclic and standby operation.

Highlights at a Glance

• Cycle-proof: Developed for a high number of charge and discharge cycles, which significantly increases service life compared to conventional VRLA batteries.
• High capacity: 50 Ah at 12 V (20-hour rate) or 45 Ah (10-hour rate) for long-lasting energy supply.
• Maintenance-free: Thanks to leak-proof AGM technology.
• Low self-discharge: Only about 3% loss of capacity per month at 20 °C.
• Flexible installation: Operation possible in various positions, except for permanent overhead installation.
• Durable: Service life of up to 10 years in the design life.

Strong Performance for Cyclic Applications

The 6FM45DX reliably delivers power in recurring discharge cycles. Its capacity is 50 Ah at a 20-hour discharge and 45 Ah at a 10-hour discharge. Thanks to the special lead-calcium-tin alloy of the grids, it allows for high cycle stability and excellent recovery after deep discharge.

Robust Technology for Demanding Environments

Thanks to the VRLA technology with AGM system, the 6FM45X is absolutely maintenance-free and leak-proof. The electrolyte is safely bound in a glass fibre mat, which allows for safe handling and operation in any position. The battery has self-closing low pressure relief valves that ensure equalisation of pressure within the cells. The housing is made of robust ABS plastic, which is impact and break resistant and, on request, is available in a flame-retardant version (UL94:V0). The low self-discharge of about 3% per month enables long-term storage with high readiness for use.

FAQs about the VISION 6FM45DX Lead-acid Battery

For which applications is the 6FM45DX best suited?

This battery has been specially developed for cyclic applications in which the battery is regularly discharged and recharged. It is ideally suited as the main power supply for electric vehicles such as wheelchairs and golf caddies, as well as for use in solar systems, telecommunication systems, UPS systems and mobile measuring devices. The battery also has VdS approval, making it optimal for safety-critical applications such as fire and burglar alarm systems.

What does "cycle-proof" mean?

A cycle-proof battery is specially designed to handle a high number of charge and discharge cycles without significantly losing its capacity or service life. This distinguishes it from conventional lead-acid batteries, which are more suited for standby operation.

How do I charge the battery correctly?

We recommend using a charger designed for AGM batteries with a capacity of 50 Ah. Follow the charging voltages recommended by the manufacturer: 13.6 V to 13.8 V for float charging and 14.4 V to 14.7 V for boost charging. Charging current that is too high can reduce battery life.

How long does the 6FM45DX battery last?

The expected service life of the battery is up to 10 years at 20°C in design life. However, the actual service life depends heavily on the individual operating conditions, depth of discharge and ambient temperature.
