"I needed a hard-to-find battery for our robot vacuum, which would no longer run for more than 10 minutes. After searching unsuccessfully at battery shops in town, I searched online and found some companies that received bad reviews for selling non-viable batteries. Then I found Battery Mart. I ordered my hard-to-find battery from Battery Mart and now our robot vacuum runs for 90 minutes. Thank you, Battery Mart!"

Frequently Asked Questions About Vacuum Batteries

Why shop vacuum batteries from Battery Mart?

What kind of battery is in a vacuum cleaner?

Most modern vacuum cleaners use a rechargeable vacuum battery made from lithium-ion or nickel-metal hydride (NiMH) cells. The exact type varies by brand and model.

Is there a difference between vacuum batteries & Roomba batteries?

A standard vacuum battery is usually a larger pack designed for stick, handheld, or upright vacuums, while a Roomba battery is a specific module built for iRobot’s robotic vacuum series. For example, Roomba 500 Series batteries use a unique NiMH pack that isn’t interchangeable with other vacuum types.

How long does a typical Roomba battery last?

A typical Roomba battery lasts about 1 to 2 years with regular use. High-quality NiMH replacements, such as those used in the Roomba 400 Series, are designed to provide long run times but naturally lose capacity over hundreds of charge cycles.

Can you replace the battery in a cordless vacuum?

Yes, most cordless vacuums allow the battery to be replaced, including popular models from Dyson, Shark, Black & Decker, and Dirt Devil. Some use simple slide-in lithium-ion packs, while others have screw-secured NiMH assemblies, but replacement is generally straightforward.

How do I know what vacuum battery replacement I need?

You can identify the correct vacuum battery replacement by checking the model number on your vacuum or on the battery label itself. This makes it easy to match your unit to the right option, whether it’s for a Dyson handheld, a Dirt Devil model, or an iRobot Roomba or Braava device. You can also search vacuum batteries by manufacturer here on Battery Mart or contact our team for help.
