Provides 12V nominal voltage and 90Ah capacity, suitable for UPS systems, backup power, telecom equipment, and renewable energy storage. Maintenance-free, spill-proof construction with valve-regulated AGM technology for reliable energy delivery and long service life in stationary installations. ## Long description Battery Volt Polska AGM OPTI 12V 90Ah is a sealed lead‑acid battery engineered for standby and cyclic applications where reliable 12V power and 90Ah capacity are required. The valve‑regulated AGM design delivers maintenance‑free, spill‑proof performance for UPS systems, backup power installations, telecom equipment and renewable energy storage. The battery is intended for stationary use and offers a balance of energy density and long service life typical for AGM technology. Advantages The sealed AGM construction provides leak‑proof operation and low self‑discharge, reducing the need for periodic maintenance. Valve regulation ensures safe recombination of gases and stable performance under float and cyclic conditions. With its 12V nominal voltage and 90Ah rated capacity, the battery supports medium to high energy requirements while remaining suitable for confined installations due to a compact rectangular case. The design also offers good vibration resistance and predictable discharge characteristics for electronic equipment. Suitable for Uninterruptible Power Supply (UPS) systems for IT and network equipment Standby backup for telecom cabinets and security systems Renewable energy storage in small off‑grid or hybrid systems Cyclic applications with regular charge/discharge cycles Stationary power for emergency lighting and control equipment When it may not be suitable This battery is designed primarily for stationary and transport‑limited installations; it is not intended for use as a starting battery for internal combustion engines. Extremely high current demands well beyond the rated capacity or continuous deep discharges can reduce service life and are not recommended. For mobile applications exposed to heavy mechanical shock or frequent orientation changes, alternative battery types specifically designed for those conditions should be considered. Key specifications Nominal voltage: 12 V Rated capacity: 90 Ah (at specified discharge rate) Battery type: Sealed lead‑acid, AGM (valve‑regulated) Maintenance: Maintenance‑free, spill‑proof design Intended use: Standby and cyclic applications, stationary installations How to use Install the battery in a well‑ventilated, dry location within the recommended ambient temperature range for best performance. Connect using appropriate terminals and correct polarity, ensuring secure and corrosion‑free connections. For standby applications, keep the battery on a suitable float charger that provides the correct float voltage and prevents overcharging. In cyclic use, follow the manufacturer’s recommended charge profile and avoid prolonged deep discharges to maximize cycle life. Observe safety precautions for sealed lead‑acid batteries, including avoiding short circuits and using appropriate protective equipment when handling. What to consider before purchase Confirm dimensions and terminal type to ensure compatibility with your battery compartment or rack. Ensure the 12V 90Ah capacity meets runtime and load requirements for your application. Check the recommended charging parameters and plan for an appropriate charger or UPS charger settings. Consider ambient temperature at the installation site, as extreme temperatures affect capacity and service life. Usage recommendations For reliable long‑term performance, maintain the battery on a dedicated float charger in standby roles and follow recommended charge/discharge cycles in cyclic use. Schedule periodic inspections for terminal condition and overall cleanliness; avoid deep discharge events whenever possible to preserve capacity and extend service life. ## FAQ ### What payment options are available?
