UPS-akku Extralink Accumulator AGM 12V 45Ah — suljettu lyijyakku (VRLA), 1 kpl, musta

Extralink Accumulator AGM 12V 45Ah is a maintenance-free sealed lead-acid (VRLA) battery designed for use in UPS, backup power systems and telecom installations. The single black unit delivers a nominal voltage of 12 V and a capacity of 45 Ah, offering a compact, spill-proof power source suitable for replacing or expanding battery banks in small to medium backup setups. The battery uses Absorbent Glass Mat (AGM) technology, where electrolyte is held in glass fibre separators to improve cyclic performance and allow repeated charge/discharge cycles without frequent maintenance.

Advantages

The sealed AGM design provides maintenance-free operation and eliminates the need to add water or handle liquid electrolyte. Its spill-proof construction and robust casing make it safe for indoor telecom cabinets, UPS enclosures and equipment racks. AGM technology ensures improved cyclic life and reliable discharge characteristics under varying loads, while the 12 V/45 Ah rating balances capacity and size for many residential and commercial backup applications.

Key specifications

How to use

Install the Extralink AGM battery in accordance with the UPS or equipment manufacturer’s instructions, observing correct polarity and secure mounting to prevent movement. Connect using appropriate battery terminals and cables sized for the expected current. Charge the battery with a compatible charger or charger circuit that supports 12 V VRLA/AGM batteries and follow recommended charge voltages and temperature compensation if provided. Avoid deep discharge beyond the equipment’s specifications to preserve battery life.

Recommendations

Store and operate the battery in a well-ventilated, temperature-stable environment away from open flames and extreme temperatures. Periodically check voltage and system state-of-charge as part of routine maintenance of the UPS or backup system. When replacing or adding batteries to an existing bank, match capacity, voltage and age where possible to ensure balanced charging and discharge across the string.
