Battery CSB HR 1221WF2 [5.1Ah] T/AK-12005/0806-T2

CSB HR Series Batteries – Reliable Power in a Compact Housing

The CSB HR 1221WF2 battery is a high-quality power source designed for applications requiring reliability and long life. It is particularly well suited for uninterruptible power supply (UPS) systems, alarms, and telecommunications and medical devices. Its compact dimensions and light weight make it easy to install even in limited spaces.

Construction and operating parameters

The battery uses AGM (Absorbent Glass Mat) technology, which means that the electrolyte is bound in a glass separator. This solution eliminates the need for maintenance and ensures safe operation – the battery is sealed and does not require electrolyte replenishment. Designed for buffer operation, it offers a lifespan of 3 to 5 years, and its construction allows for over 260 charge and discharge cycles at full load. This makes it an investment for years to come.

It is worth noting its discharge current – even short-term loads of up to 90A are not a problem. The nominal voltage of 12V and the capacity of 5.1Ah provide a stable power supply to connected devices. The battery is factory charged and ready to use immediately after removal from the packaging.

Application and compatibility

This CSB battery model is a universal solution that can be used in many areas:

• UPS systems: ideal for maintaining power to devices in the event of a power failure. Compatible with popular APC (BackUPS, SmartUPS), Ever, Orvaldi and other models.
• Alarm and fire systems: provides reliable power for security systems.
• Telecommunications: stable power supply for communication devices.
• Medical equipment: important in applications requiring continuous power to medical equipment.
• Emergency lighting: guarantees the operation of lighting in crisis situations.

The HR1221WF2 battery is also a replacement for many other lead-acid battery models, such as Panasonic LCR12V4P/5P, Yuasa NPX-25 or Rocket MK ES4-12, which makes it easier to modernize existing systems.
