Compatible UPS Battery Kit

This three-battery kit replaces the internal cells of an Eaton 5SC 1500 uninterruptible power supply. Each unit is a 12V 9Ah sealed lead-acid block designed for high-rate discharge. The pack arrives factory fresh with installation instructions included. It restores backup runtime to the original specification.

Upgrade From Worn Cells

UPS batteries degrade after several years of float service and deep discharges. Swapping all three cells at once prevents the imbalance that shortens the life of a mixed-age string. The jump is worth it when runtime has fallen below useful levels or the UPS signals a battery fault.

Capacity and Runtime Headroom

The combined 12V 9Ah configuration supports the 1500 VA unit’s rated load for its designed autonomy period. It handles typical server and network gear through short outages and voltage sags. Runtime drops sharply once the connected load exceeds the UPS rating or when cells approach end of life.
