FAQs

Do I need to install these RBC24 batteries into my existing battery tray?

Yes. This product includes 4 individual 12V 9Ah AGM batteries that must be installed into your existing APC RBC24 battery tray. You will need to reuse your original wiring and connectors to assemble the battery pack.

Before ordering, we recommend checking your current battery setup to ensure it uses four 12V 9Ah batteries with the same dimensions and terminal type.

Do I need to replace all 4 RBC24 batteries at the same time?

Yes, it is strongly recommended to replace all 4 batteries at the same time. Mixing old and new batteries can reduce performance, shorten battery life, and may cause improper charging in your UPS system.

How long will my APC RBC24 battery last?

Most UPS batteries last 3–5 years, depending on usage and ambient temperature.

Is this battery safe for home or office use?

Yes. It’s a VRLA battery – sealed, maintenance-free and designed for standby UPS power.
