It’s recommended you replace your Roomba battery every 2 years to keep it running as it should.
While the process is super simple, there is not a lot of useful info showing you how to do it. This guide will walk you through the steps to replacing your Roomba battery along with other tips.
What You Need
To swap out the battery, you only need three things, the Roomba, a Philips head screwdriver, and the new battery.
Remove the dirt bin collector from your Roomba Robot Vacuum as shown below.
Flip the robot vacuum over and unscrew the side brush using your Philips head screwdriver.
Using the Phillips head screwdriver, remove the four screws under the Roomba, as shown below.
Note: The four screws don’t come completely out. This is to make it easy for when you reinstall it.
With all four screws lose and still in place lift on one side of the Roomba and the black plastic piece should come off with ease.
With the bottom case removed the battery can be seen.
There is nothing else holding the battery in place so all you need to do is lift it out with the two tabs on either side.
The battery can only go in one way; match up the notch on top and it will slide in.
When you insert the new battery, make sure the metal connections of the battery touch the metal connections of the robot. I’ve seen people put the battery in upside down before. You want the two tabs to stand up towards you, like in the picture below.
Reassembly is the reverse order.
Note: Don’t over tighten the four screws as it could make the buttons on top not click or work.
Should You Use The Manufacturer’s Battery?
It’s recommended that you use the manufacturer’s battery, but in my case, I went with a 3rd party.
As you can see, the 3rd party battery is not identical, but it does fit, and it does work fine.
You can see how the two batteries are different, but either one fits and works fine. You can also make out the specs of the batteries too.
