How do you choose an APC UPS battery backup?

Choose a UPS by matching its watt capacity to your equipment and deciding which devices need battery power during an outage. Then compare outlet types, output waveform, AVR, replaceable batteries and surge protection.

How much UPS capacity do you need?

Add the power draw of the equipment you plan to connect and stay within the UPS's watt limit. The 425VA models are aimed at lower-power equipment, while the 900W and 1000W models provide more headroom for a computer and several accessories.

VA and watts are different ratings, so don't compare units by VA alone. Check the watt rating and your equipment's requirements before plugging in a full setup.

Which outlets should get battery backup?

Reserve battery backup outlets for equipment that needs to keep running long enough to save work, maintain a network connection or shut down safely. Put less critical gear on surge-only outlets, which don't provide battery power during an outage.

Outlet counts vary even within the APC range. The BE425M has 4 backed-up outlets, the BR1500MS2 has 6, and the BX1500M has 5.

Do you need sine wave output or AVR?

Sine wave output can matter for equipment whose power supply specifies it. The BR1500MS2 offers pure sine wave output, and CyberPower says the CP1500PFCLCD supports active PFC and conventional power supplies with sine wave output.

AVR corrects some voltage changes without switching to battery power. The BR1500MS2, BX1500M, 1000VA/600W Pro and CyberPower CP1500PFCLCD list AVR, which can preserve battery charge for an outage.

Is a UPS the same as a surge protector?

No. A UPS adds temporary battery power to selected outlets, while a surge protector helps guard against voltage spikes without providing outage runtime.

For the basics, read our surge protector buying guide.

An APC UPS battery backup and surge protector combines those roles on its battery-backed outlets. Check the outlet labels so you know which devices stay powered when utility power stops.

Which APC UPS battery backup should you choose?

Choose the APC BR1500MS2 for pure sine wave output and a full home office setup, or the BE425M for a router and modem in a small space. Pick the BE600M1 for a compact desk with USB charging, and consider the BX1500M if AVR and an LCD matter more than pure sine wave output.

If you're comparing other brands, see our guides to best Eaton UPS battery backups and best Tripp Lite UPS battery backups. Check your equipment's power draw and plug requirements before choosing a unit.

The APC BX1500M uses a replaceable battery, so owners planning a later battery swap can also review our best APC BX1500M replacement battery guide. For outage behavior, read how a UPS switches to battery power and whether a UPS works during a power outage.

Frequently asked questions

Which APC UPS battery backup is best for a computer?

The APC BR1500MS2 is a strong APC choice for a demanding computer setup because it has 1500VA/900W capacity, pure sine wave output and 6 battery backup outlets. The BE600M1 fits a lower-power desk, while the BE425M is better suited to a router or modem.

Check your equipment's combined power draw before choosing.

What is the difference between battery backup and surge-only outlets?

Battery backup outlets supply temporary UPS battery power during an outage and also provide surge protection. Surge-only outlets provide surge protection but don't keep equipment running when utility power fails.

Use backed-up outlets for gear you need to save or keep connected, then reserve surge-only outlets for less critical devices.

Do APC UPS battery backups protect a router during an outage?

Yes. APC's BE425M has 4 battery backup outlets and is described for low-power equipment such as routers and modems.

The BE600M1 provides 5 backed-up outlets and a USB-A charging port.

Runtime depends on the connected load, so prioritize the router and modem if keeping internet access matters.

Should I choose pure sine wave output?

Pure sine wave output can be a useful fit for a computer or other equipment whose power supply calls for it. The APC BR1500MS2 provides pure sine wave output, and the CyberPower CP1500PFCLCD specifies sine wave output for active PFC and conventional power supplies.

Check your equipment's requirements before deciding.

Can I replace the battery in an APC UPS?

Some APC models here have user-replaceable batteries. The BE600M1 and BR1500MS2 specify replaceable batteries, and APC names compatible replacement battery models for each.

Before ordering a battery, match the UPS model and compatible battery number.

For the BX1500M, see our APC BX1500M replacement battery guide.
