Compatible replacement kit for OPTI-UPS PS1500B

This kit provides three 12V9A sealed lead-acid batteries designed as direct replacements for the OPTI-UPS PS1500B uninterruptible power supply. It restores backup runtime when the original cells reach end of life. The package suits administrators maintaining existing PS1500B units in server rooms or network closets. Buyers needing a different voltage, capacity or form factor should look elsewhere.

Factory-fresh cells with installation guide

Each battery is supplied factory fresh and rated for high-rate discharge to match the UPS load profile. The bundle includes comprehensive replacement instructions so technicians can swap the cartridge without specialised tooling. No management software, cables or mounting hardware are included. Installers who require hot-swap trays or monitoring modules must source them separately.

Three 12V9A batteries weighing 21 units

The decisive specification is the triplet of 12V9A SLA blocks totalling a shipped weight of 21. This exact voltage, ampere-hour rating and physical count determine fit and runtime inside the PS1500B chassis. Verify that the host UPS accepts this three-brick configuration before purchase. Systems requiring a different brick count or chemistry will not accept this kit.
