12V 9.0Ah UPS Replacement Battery

This sealed lead-acid battery uses AGM technology and fits APC ES500, ES550, LS500, RBC110 and RBC2 units. It delivers 12 volts and 9.0 ampere-hours in a maintenance-free package. The physical dimensions are 5.94 length, 2.56 width and 3.66 height with T1/T2 terminals. It is a direct 100% OEM replacement that increases capacity over older 7.5Ah cells.

Suits owners of listed APC models needing higher

Buyers whose UPS requires a different voltage, terminal layout or form factor should look elsewhere. Units not compatible with the ES500, ES550, LS500, RBC110 or RBC2 part numbers cannot use this battery. Installers needing a 7Ah original-spec cell without the capacity increase should verify their chassis space first.

Simple drop-in installation with T1/T2 terminals

The battery is sealed and non-spillable so it can be mounted in any orientation without electrolyte leakage. Common issues include forgetting to disconnect the UPS from mains before swapping cells and reversing the terminal polarity. Ensure the replacement fits the 5.94 by 2.56 by 3.66 millimetre cavity and that the terminal connectors seat fully on the T1/T2 posts.

Questions about this item

Does the 9.0Ah battery fit the same compartment as my old 7.5Ah unit?

The battery measures 5.94 by 2.56 by 3.66 and uses T1/T2 terminals, so it fits the same space and connects to the same leads.

Will the ES500 or ES550 charger handle the higher 9.0Ah capacity?

Yes, the unit is a 100% OEM replacement for APC ES500, ES550, LS500, RBC110 and RBC2 models and the charger works normally with the increased capacity.

How can I confirm the battery is holding charge after I install it?

Run a self-test on the UPS; the display should show full runtime and no replace-battery indicator when the 12V 9.0Ah pack is healthy.
