About APC Smart-UPS 1000VA Replacement Batteries

APC Smart-UPS 1000 replacement batteries

The APC Smart-UPS 1000 VA family spans several generations — the legacy SU and SUA models, the SMC LCD models, and the extended-runtime SU-XL models. Their sealed lead-acid (VRLA) batteries wear out after about 3–5 years; a fresh pack restores full runtime. Because the battery differs significantly between generations, confirm your exact model before ordering.

For the full range see APC replacement batteries and APC Smart-UPS batteries.

Which battery does my Smart-UPS 1000 take?

The pack voltage depends on the generation: some models use a single 12 V battery, others a 24 V pack (two 12 V), and rack / XL models a 48 V pack (four 12 V). Capacity also varies (roughly 6–17 Ah). Because of this spread, match by your exact model number (e.g. SMC1000-2UC, SU1000RM2U, SU1000XLNET) — the VA rating alone is not enough.

How to identify the right battery

Read the model number on the rear or side label, or the front LCD. Select the matching battery below, or send us your model number and we'll confirm the correct pack — usually within 1 business day.

Genuine APC vs compatible aftermarket

Both restore full runtime. Genuine APC: OEM cartridge with a 2-year APC battery warranty. Compatible aftermarket: the same form factor and connector for your model, built from quality VRLA cells, typically 30–50 % less, with a 1-year UPSPLUSBATTERY warranty.

How long does it last?

3–5 years at 20–25 °C; heat roughly halves life for every ~8 °C above 25 °C. See when to replace a UPS battery.

How to replace

Smart-UPS batteries are hot-swappable on most models — the UPS keeps protecting the load:

1. Confirm the correct pack for your exact model.
2. Open the battery compartment (front bezel on tower; tray latch on rack).
3. Disconnect the battery connector.
4. Slide the old pack out and the new one in.
5. Reconnect until it clicks and run a self-test.

FAQ

What voltage is the Smart-UPS 1000 battery?

It depends on the model — 12 V, 24 V or 48 V across the SU / SUA / SMC / XL generations. Match by exact model number.

I have an SMC1000 — is that the same as an SU1000?

No — different generations use different packs. Confirm against your exact model.

How often should I replace it?

Every 3–5 years; sooner in warm spaces.
