Vision Lead-acid battery CP1250HF2 with 12V and 5Ah

Description

Product information

The Vision CP1250HF2 is a high-quality, valve-regulated lead-acid battery (VRLA) with 12 Volt nominal voltage and 5 Ah capacity. This HF Series battery is a high-current type specifically designed for demanding standby operation. Equipped with maintenance-free AGM technology, this battery provides an extremely reliable power supply for critical applications that require high performance in a short time, such as in uninterruptible power supplies (UPS).

Highlights at a glance

  • High current capability: Optimised for high discharge currents, ideal for powerful UPS systems and other critical loads.
  • Long service life: Designed for a service life of up to 5 years in standby mode (float) at 20 °C.
  • Reliable capacity: 5 Ah at 12 V for secure power supply with a small footprint.
  • Maintenance-free: Fully sealed AGM technology with efficient gas recombination makes maintenance unnecessary.
  • Flexible mounting: Operation is possible in all positions, except permanent use upside down.
  • Tested quality: Manufactured to the highest quality standards, ideal for use in safety-relevant devices.

Powerful performance for safety-critical applications

The Vision CP1250HF2 delivers a nominal capacity of 5 Ah in a 20-hour discharge. Its particular strength lies in its ability to deliver very high currents for short periods of time. This makes it destined for use in uninterruptible power supplies (UPS) that have to supply high loads when starting up. Its design for standby parallel operation ensures that it provides full power immediately in the event of a power failure.

Robust technology for demanding environments

Thanks to the VRLA technology (Valve Regulated Lead Acid) with an electrolyte bound in glass fibre fleece (AGM system), the CP1250HF2 is completely maintenance-free and leak-proof. The battery features self-regulating safety valves that ensure safe pressure equalisation in the event of overcharging. The low self-discharge of less than 3% per month at 20°C enables long-term storage. The robust housing made of impact-resistant ABS plastic is available on request also in a flame-retardant version according to UL94:V0.

FAQs about the Vision CP1250HF2 lead-acid battery

For which applications is the CP1250HF2 suitable?

The battery is ideal for demanding standby applications with high power requirements:

  • Uninterruptible power supplies (UPS)
  • Data centres and telecommunication systems
  • Safety lighting and emergency lighting systems
  • Fire alarm systems (FAS) and intruder alarm systems (IAS)
  • Medical and clinical devices

What does the designation "HF" and "high current capability" mean?

The designation "HF" for Vision batteries stands for "High Rate" or high current. These batteries are constructed with thinner lead plates and a larger active surface, resulting in reduced internal resistance. This allows them to deliver significantly higher currents for short periods than standard batteries of the same capacity, which is crucial for starting motors or operating UPS systems.

What is the difference compared to a CP1250A standard battery?

Although both have the same capacity and size, the CP1250HF2 is specially optimised for high power delivery. The standard battery CP1250A is an all-purpose type. The HF type is the first choice when maximum power output is required in the first few minutes of a power failure, as is the case in UPS systems.

What is the correct charging voltage for this battery?

For maximum service life in standby operation, the float charge voltage at 20 °C should be between 13.5 V and 13.8 V (2.25 V to 2.30 V per cell). Temperature compensation is recommended for optimal battery maintenance.

Is the battery maintenance-free?

Yes, thanks to sealed AGM technology, the battery is completely maintenance-free. There is no need to top up with water, and it can be safely operated in devices and indoors.

Can I use this battery for an electric scooter?

Although the battery would technically work, it is not ideal for this purpose. It is optimised for standby operation. For electric scooters that require daily charge and discharge cycles, we recommend cycle-resistant batteries (recognisable by "DX" on Vision), as these achieve a significantly longer service life in cyclic operation.
