Let me tell you, this BAKTH battery is a game-changer for older Roomba models. I popped it into my trusty Roomba 620, and boom – it’s like giving my vacuum a caffeine shot! The 3000mAh capacity means I get noticeably longer cleaning sessions compared to my worn-out original battery.

Installation? Easier than assembling IKEA furniture. Just slide out the old battery, click this one in, and you’re golden. No weird error messages or connection issues – it recognized it immediately like they were old friends.

Now, heads up about the charging quirk some reviewers mentioned. Mine did the same ‘fake death’ act the first charge cycle (Roomba docked after 2 minutes like it gave up on life). But after a full overnight charge? Performed like a champ – cleaned my entire downstairs without whimpering for the dock.

For the price? Absolute steal. Performs just as well as OEM batteries that cost twice as much. My Roomba’s runtime is back to its youthful 90-minute glory. Pro tip: Do the full 16-hour initial charge they recommend – it really does maximize battery life.

Only con? The packaging feels a bit cheap, but hey – it’s what’s inside that counts. After 3 months of daily use, still holding strong. If your Roomba’s dying mid-clean, this battery’s your wallet-friendly lifeline.
