Verzegelde AGM-accu QOLTEC 12V 2,3Ah voor UPS- en back-upsystemen, max. ontlading 34,5A

Sealed AGM battery QOLTEC 12V 2.3Ah for UPS and backup systems, max discharge 34.5A is a maintenance-free, valve-regulated lead-acid (VRLA) battery designed for standby and cyclic applications. With a nominal voltage of 12V and a rated capacity of 2.3Ah, this sealed AGM battery is intended to provide reliable auxiliary power for small uninterruptible power supplies, alarm panels, emergency lighting and other compact backup systems. The spill-proof construction and absorbed glass mat (AGM) technology ensure safe indoor installation, low self-discharge and a long shelf life for occasional use.

Advantages

The sealed AGM design eliminates the need for regular electrolyte maintenance and reduces the risk of leakage during installation or service. AGM construction offers good low-temperature performance and stable internal resistance, enabling consistent discharge up to the specified maximum of 34.5A. The compact form factor and standardized terminal layout make integration into many UPS and security enclosures straightforward. Overall, the battery provides predictable standby performance and easy handling for service technicians.

Suitable for

• Small UPS units for home or office equipment
• Alarm and security control panels
• Emergency and exit lighting systems
• Portable backup modules and network devices
• Hobby and low-power DC projects requiring 12V standby power

Key specifications

• Nominal voltage: 12 V
• Rated capacity: 2.3 Ah (at standard discharge rate)
• Maximum discharge current: 34.5 A
• Technology: Sealed AGM, VRLA (absorbed glass mat)
• Maintenance: Maintenance-free, spill-proof
• Intended use: Standby and small cyclic applications

How to use

Install the sealed AGM battery in a well-ventilated indoor enclosure that meets the equipment manufacturer’s recommendations. Connect positive and negative terminals observing correct polarity and ensure terminal screws are tightened to the torque specified by the host device. For standby applications, keep the battery charged by the UPS or charger to avoid deep discharge; for long storage, recharge periodically to maintain capacity. Avoid short circuits and exposure to open flames; do not attempt to open or service the sealed battery.

Recommendations

Store the battery at moderate temperature and charge to approximately 40–60% if it will be unused for extended periods. Replace batteries in pairs when used in parallel or in multi-battery UPS packs to ensure balanced performance. For reliable runtime estimates, consult the UPS or equipment documentation and consider the battery’s nominal 2.3Ah capacity and maximum discharge capability when calculating load and run time.
