I was skeptical at first, but this replacement battery completely revived my aging Roomba 650. The original battery died after years of service, and I didn’t want to spend a fortune on an OEM replacement. This one was a fraction of the cost and works just as well—maybe even better.

The installation was straightforward. After removing the old battery (just lift it out using the straps), I popped in the new one, and my Roomba powered up instantly. No complicated setup, no errors—just a smooth transition. The included side brushes were a nice bonus, though I didn’t need them for my model.

Performance-wise, this battery lasts noticeably longer than the original. My Roomba now runs for a solid 40-45 minutes on a full charge, covering my entire main floor without quitting early. It even sounds stronger, like it’s regained its youthful energy. The charging time is quick, and there’s no memory effect, so I can top it off whenever without worrying about battery health.

One minor quirk: my Roomba occasionally needs a slight nudge to dock properly, but that’s more about the robot’s alignment than the battery. For the price, this is an unbeatable upgrade. If your Roomba is struggling, give this battery a try—it’s like giving your old vacuum a second life!
