Best Roomba Replacement Batteries (For All Models)

A Roomba battery usually lasts for 1-2 years on regular use. The lifetime can vary depending on how often you use it. But at some point, you have to replace the old battery with a new one. But when you look at the price of those iRobot official batteries, you might put changing it on hold.

Well, that’s not good for the robot, is it? Not changing the battery has downsides of its own, which could end up costing you more than the battery. So why not look for alternative options?

Caution: iRobot recommends that you use their original batteries for the Roomba to get optimum performance. If you choose to use a third-party battery, you might not get the same performance.

Several authentic third-party manufacturers make batteries compatible with Roombas. They might have different power and voltage ratings than the original ones, but they’ll do the job just fine. And that too at a cheaper price. But before you hurry and some Roomba replacement batteries, make sure you are buying the right one.

Choosing the right Roomba replacement battery

You’ll be surprised to know that all Roombas don’t use the same type of battery. There are a total of 6 different types of Roomba batteries compatible with different models. Let’s get a more clear picture in the table below.
