Key Features

• Direct replacement: The battery is designed to match the Minuteman MN525 form factor so it will fit most UPS units that accept that model without modification.
• 12V output: The 12V voltage rating ensures compatibility with UPS systems and chargers expecting a standard 12 volt sealed lead acid cell.
• 9Ah capacity: The 9Ah capacity provides a predictable runtime similar to the original battery for short-duration backup needs and controlled shutdowns.
• F2 terminals: F2 terminal type makes installation straightforward where F2 connectors are used, reducing the need for adapter parts.
• Brand replacement: As an AJC brand replacement, it offers a lower-cost alternative to brand-name packs while keeping the same key electrical specs.
