Battery Backups vs. Surge Protectors: What’s the Difference?

While both battery backups and surge protectors provide protection from electrical issues, they serve different purposes.

  • Battery Backup (UPS): Primarily provides temporary power during a blackout or power disruption, allowing you to continue using your devices or shut them down safely. It doesn’t protect against surges, although some UPS units do have surge protection built in.
  • Surge Protector: Protects devices from electrical spikes and surges. It doesn’t provide backup power during an outage but can prevent damage from power surges.

Can You Use Both?

Yes! In fact, combining both is the best option for comprehensive protection. You can plug your battery backup (UPS) into a surge protector to shield it from power surges while also benefiting from backup power during outages. Some high-quality UPS units also include surge protection features, so it’s essential to check the specifications before buying.


How to Choose the Right Battery Backup and Surge Protector

When selecting a battery backup or surge protector, it’s important to match the specifications to your needs. Here’s what to consider:

Choosing a Battery Backup (UPS):

  1. Wattage Capacity: The UPS should have enough wattage to support all the devices you want to plug into it. Check the wattage of your devices (laptops, monitors, routers, etc.) and choose a UPS that can handle the total load. A good rule of thumb is to select a UPS that provides at least 20-30% more wattage than your total needs.
  2. Battery Runtime: The runtime of a UPS depends on the size of the battery and the number of devices connected. For example, a small UPS might give you 10-15 minutes of runtime, while a larger unit can provide hours of power.
  3. Ports and Outlets: Ensure the UPS has enough outlets for your devices and that the outlets are the right type (e.g., standard or specialized for high-voltage devices).
  4. Form Factor: Battery backups come in different sizes. If you have limited space, look for compact models. If you have a lot of equipment, choose a larger tower-style unit.

Choosing a Surge Protector:

  1. Joule Rating: This indicates how much energy the surge protector can absorb before it fails. Look for a surge protector with a higher joule rating if you’re protecting valuable equipment.
  2. Number of Outlets: Make sure the surge protector has enough outlets for all your devices. Some models also include USB ports for charging devices like smartphones.
  3. Response Time: Choose a surge protector with a fast response time to quickly divert excess voltage away from your devices.
  4. Warranty: Many surge protectors offer warranties or insurance for connected devices in case they are damaged. Check the terms and ensure it covers the full cost of replacing your equipment if necessary.

Conclusion: Why Every Home and Office Needs Protection

Power surges and outages are unpredictable, but with the right equipment, you can safeguard your devices from electrical disruptions. Battery backups provide critical backup power during outages, while surge protectors defend your electronics against sudden spikes in electrical energy.

Investing in both is a smart way to protect your valuable equipment, preserve your data, and avoid costly repairs or replacements. With a UPS and surge protector, you’ll have peace of mind knowing your devices are well-protected no matter what happens to the power supply.


Protect your tech and ensure uninterrupted productivity by choosing the right combination of battery backup and surge protection today!
