Kit contents and intended use

This kit supplies two sealed lead-acid batteries rated at 12 volts and 18 ampere-hours each. It is designed as a direct replacement for the ONeAc ON1300 uninterruptible power supply. Buyers who need a different voltage, capacity or form factor should look elsewhere.

Sustained discharge behaviour

The batteries are built for high-rate discharge, delivering stable power during extended outages rather than only short bursts. Factory-fresh cells ensure consistent runtime from the first installation. Units that require longer autonomy than this capacity provides will need a different solution.

Compatibility checks before ordering

Verify that your UPS model is the ONeAc ON1300 and that the chassis accepts two 12 V 18 Ah blocks glued together as a cartridge. Confirm the physical dimensions match the original battery tray. Systems using a different battery count, voltage or connector layout cannot use this kit.

Questions about this item

How much heat do the two 12V18A batteries generate when the UPS runs continuously?

The sealed lead-acid cells produce only modest warmth during normal float charging; the kit is designed to operate inside the ON1300 enclosure without additional cooling.

What must I already have to install this kit in my ON1300 UPS?

You need the ON1300 UPS unit itself and basic hand tools to open the battery compartment and connect the two glued 12V18A cartridges.

Will the 12V18A cells work with the original charger in an older ON1300 unit?

Yes, the replacement cartridges match the voltage and capacity the ON1300 charger expects, so the existing charging circuit manages them correctly.
