High performance for cyclical applications
The 6FM55DX reliably supplies power in recurring discharge cycles. With its capacity of 55 Ah, this battery is an excellent choice for mobile applications and systems with high energy requirements. Its special design, which utilises lead-calcium-tin alloys, enables high cycle stability and excellent recovery after deep discharge.
Robust technology for demanding environments
Thanks to the VRLA technology with AGM system the 6FM55DX is absolutely maintenance-free and leak-proof. The electrolyte is securely bound in glass fibre fleece, ensuring safe handling and operation in any position. The battery has self-sealing low pressure relief valves that ensure pressure equalisation within the cells. The case is made of robust ABS plastic, which is impact and break-resistant and, if required, is also available in a flame-retardant version (UL94:V0).

FAQs on the VISION 6FM55DX lead-acid battery
For which applications is the 6FM55DX best suited?
This battery has been specially developed for cyclic applications where 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 and mobile measuring instruments.
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 batteries, which are more designed for standby operation.
How do I charge the battery correctly?
We recommend using a charger designed for AGM batteries with a capacity of 55 Ah. Observe the charging voltages recommended by the manufacturer. Too high a charging current can shorten the battery's service life.
How long does the 6FM55DX battery last?
The service life of the battery is up to 10 years at 20 °C in the designed life. However, the actual service life depends strongly on the individual operating conditions, the depth of discharge and the ambient temperature.

The Vision 6FM75TDX is a high-performance, cycle-proof and valve-regulated lead-acid battery (VRLA) with 12 Volt nominal voltage and 75 Ah capacity. Designed for demanding cyclic applications, this battery combines maintenance-free AGM technology with a robust design. It offers a reliable and long-lasting energy solution for applications where repeated charging and discharging is a daily occurrence, such as in solar technology, mobile applications or rehabilitation technology.Highlights at a glanceHigh cycle stability: Developed for demanding cyclic use with a long service life.Strong capacity: 75 Ah at 12 V for long-lasting and reliable power supply.Maintenance-free AGM technology: The advanced AGM (Absorbent Glass Mat) technology ensures leak-proof and maintenance-free operation.Low self-discharge: With only about 3% self-discharge per month, the battery is ready for use even after longer periods of disuse.Flexible installation: Operation is possible in all positions, with the exception of continuous upside-down use.Robust construction: The durable ABS plastic housing reliably protects the battery against mechanical impact.Reliable energy for demanding cyclesThe Vision 6FM75TDX has been specially optimised for cyclic operation. It delivers a nominal capacity of 75 Ah on a 20-hour discharge (C20). Its particular strength lies in its ability to be repeatedly deeply discharged and recharged without significant loss of capacity. This makes it the ideal choice for solar installations, electric vehicles and other mobile power supplies that require constant and reliable performance.Advanced technology for maximum longevityThanks to the VRLA technology (Valve Regulated Lead Acid) in combination with the AGM system, where the electrolyte is contained in a glass fibre mat, the 6FM75TDX is fully sealed and maintenance-free. This not only prevents leaks, but also enables efficient gas recombination within the cell. The battery features low internal resistance, allowing high current draw. The low self-discharge rate ensures that the stored energy is preserved for long periods, which is particularly advantageous for seasonally used equipment.Features ModelVision 6FM75TDX Cyclic Battery typeVRLA AGM Nominal voltage (V)12 Capacity (Ah)75 (at 20h rate) Maximum discharge current750A (for 5 seconds) Charge voltage (float)13.6V - 13.8V Charge voltage (cycle operation)14.4V - 15.0V Operating temperature (°C)Charge: 0 ~ 40 / Discharge: -20 ~ 50 Storage temperature (°C)-20 ~ 40 Service lifeapprox. 600 cycles at 80% depth of discharge Dimensions (L/W/H, mm)260 x 168 x 214 Weight (kg)approx. 23.5 ConnectionM6 internal thread CertificationsISO9001, ISO14001, CE, UL FAQs about the Vision 6FM75TDX lead-acid batteryFor which applications is the Vision 6FM75TDX suitable?This battery is specially designed for cyclic applications and is excellently suited for:Solar and photovoltaic off-grid systemsMotorhomes, caravans and boatsElectric wheelchairs and mobility scootersCleaning machines and automated guided vehicles (AGVs)Uninterruptible power supplies (UPS) with high cycle requirementsWhat does the term "cycle-proof" mean?Cycle-proof means that the battery is designed to be frequently and deeply discharged and then fully recharged.
