The APC replacement battery RBC18 is an original replacement battery for Uninterruptible Power Supplies (UPS) of the brand APC. It serves as a replacement for worn-out or exchanged batteries in compatible UPS systems and ensures continuous power supply for sensitive IT and network equipment during power outages. The battery is specifically developed for use in APC UPS models and provides a reliable energy source in emergencies.

Applications
RBC18 is designed for use in uninterruptible power supplies used in offices, server rooms, network infrastructures, and other critical IT environments. It replaces the integrated battery in the device when it reaches the end of its service life, maintaining the functionality of the UPS. The battery is intended for use in devices such as PS250I, PS450I, SC450RMI1U, and other model-dependent compatible APC UPS systems.

Features and Equipment in Detail
The replacement battery RBC18 is based on valve-regulated lead-acid (VRLA) technology, which is maintenance-free and suitable for use in enclosed systems. This technology prevents leaks and allows for safe installation in indoor environments. The battery is designed as a hot-swap battery, meaning it can be replaced while the UPS is in operation, without requiring the connected device to be powered down. This is particularly important in environments where interruption of power supply is not acceptable.

Technology Explained Simply
The battery has a nominal voltage of 6 V DC and is designed as a lead-acid battery with a service life of three to five years. The valve-regulated lead-acid (VRLA) technology ensures that the battery does not release acid, making it safe in operation. The battery is delivered fully assembled and ready for use, so it can be directly installed into the UPS device without additional assembly or configuration. The operating temperature ranges from 0 to 40 °C, and the relative humidity during operation can reach up to 95 %, enabling flexible use in various environments.

Compatibility and Accessories
The RBC18 is specifically developed for APC UPS models and has been tested and certified for 100% compatibility with the respective devices. Compatible models include, among others, PS250I, PS450I, SC450RMI1U, SC250RM1U, SC250RMI1U, SC450R1X542, SC450RM1U, and SC450RMI1U. Exact compatibility can be verified via the APC support platform at apc.com. The battery is not a universal replacement part, but specifically designed for the mentioned APC models.

Installation and Mounting
Installation is performed by simply inserting the battery into the designated slot in the UPS device. Since it is a hot-swap battery, replacement can be done without shutting down the system. The battery is delivered fully assembled and ready for use, so no additional components or tools are required. Dimensions are 35.6 mm (width) × 302.3 mm (depth) × 101.6 mm (height), and the weight is 2.59 kg.

Operational Advantages
Using the original APC replacement battery RBC18 ensures optimal performance and reliability of the UPS. The battery extends the service life of the UPS system and ensures stable power supply in case of failure. The maintenance-free design reduces maintenance effort, and the hot-swap function enables seamless replacement without interrupting power supply. The battery is designed for use in environments with relative humidity up to 95 % and temperatures between 0 and 40 °C, enabling broad applicability in various indoor spaces.
