Vision lead-acid battery 6FM134DX with 12V and 134Ah

The Vision 6FM134DX is a cycle-resistant, valve-regulated lead-acid battery (VRLA) with a nominal voltage of 12 volts and a capacity of 134 ampere hours. It is specially designed for demanding applications with recurring charging and discharging cycles. Thanks to the AGM technology (Absorbent Glass Mat), this battery offers a reliable, leak-proof and long-lasting power supply. It is the ideal solution for systems that require high cycle stability and deep discharges, and is ideal for cyclical as well as standby operation.

Highlights at a glance

• Cycle-resistant: Designed for a high number of charging and discharging cycles, which considerably extends the service life compared to conventional VRLA batteries.
• High capacity: 134 Ah at 12 V for long-lasting and stable energy supply.
• Maintenance-free: Thanks to the leak-proof AGM technology.
• Low self-discharge: Only approx. 3 % capacity loss per month at 20 °C, which enables long-term storage.
• Flexible installation: Operation is possible in various positions, except for permanent overhead installation.
• Long service life: A service life of up to 10 years in Design Life.

Strong performance for cyclical applications

The 6FM134DX reliably delivers power in recurring discharge cycles. With a capacity of 134 Ah at a 20-hour discharge, this battery is an excellent choice for mobile applications and systems with high energy needs. Its special design, which uses lead-calcium-tin alloys, enables high cycle resistance and excellent recovery after deep discharge.

Robust technology for demanding environments

Thanks to the VRLA technology with AGM system, the 6FM134DX is absolutely maintenance-free and leak-proof. The electrolyte is safely bound in a glass fibre mat, which enables safe handling and operation in any position. The battery has self-closing low-pressure relief valves that ensure pressure equalisation within the cells. The case is made of robust ABS plastic, which is also available in a flame-retardant version (UL94:V0) upon request. The low self-discharge of about 3 % per month enables long-term storage with high readiness for use.

FAQs about the VISION 6FM134DX lead-acid battery

For which applications is the 6FM134DX best suited?

This battery was specially developed for cyclical applications where the battery is regularly discharged and recharged. It is ideal as the main power supply for electric vehicles such as wheelchairs, cleaning machines, golf caddies and for use in solar systems, telecommunication systems, UPS systems and medical devices.

What does "cycle-resistant" mean?

A cycle-resistant battery is specially designed to withstand 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 designed for standby operation.

How do I charge the battery correctly?

We recommend the use of a charger suitable for AGM batteries with a capacity of 134 Ah. Observe the charging voltages recommended by the manufacturer: for buffer charging (float operation) 13.6 V to 13.8 V and for cycle charging (boost operation) 14.4 V to 14.7 V. A charging current of more than 40 A can shorten the battery's service life.

How long does the 6FM134DX 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 greatly on the individual operating conditions, the depth of discharge and the ambient temperature. For example, over 650 cycles can be achieved when used at 50% depth of discharge.
