Replacement Battery for 5kVA–6kVA UPS

The Eaton EBP-1803 is a 5000 mAh lead-acid battery cartridge designed for select Eaton 5kVA to 6kVA double-conversion UPS systems and compatible extended battery modules. It serves data-centre operators and IT managers who need to maintain continuous uptime on supported 9PX and SU series units.

Hot-Swappable Cartridge Installation

The cartridge is hot-swappable so the UPS stays online while the pack is exchanged, removing the need for a scheduled shutdown. Valve-regulated sealed construction prevents electrolyte leakage during handling. The proprietary form factor means the pack fits only the listed Eaton models; forcing it into an unlisted chassis will damage the connector and void the battery.

Lead-Acid Chemistry Limits

Lead-acid chemistry delivers an inexpensive cost per watt-hour but imposes a typical service life of three to five years before capacity degrades below useful levels. Extended runtime is achieved by chaining multiple EBMs such as the BP180RT or 9PXEBM180RT units, yet each additional pack adds weight and requires adequate ventilation because the sealed cells still vent gas under heavy charge.

Questions about this item
