Is ok to use on 551?** A: Works on both the 550/551 and other 500 series versions. **Q: The capacity is 3.8 or 5 Ah?** A: It is listed as 5 Ah. **Q: Does it work with roomba 625?** A: I won't swear to it. Check the ad. If memory serves, it wax saying it fit 500-series, 600-series, etc. Mine is a 590, which was not number to which it specifically referred, but it said 500-series to I tried it. Seems to work just fine. If the ad says 600-series, you're probably good to go. It's a great deal less expensive than the Roomba battery on that website, and shows a substantially higher amp-hour rating. **Q: RemotesLost mine need a nother one** A: I purchased this unit, not knowing 100% for sure it was the right one to replace the old battery in our Roomba. It was! Fast delivery and it works flawlessly. Our Roomba is like new! Couldn't be happier. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Happy with the price and ease of installation. *by K***H on September 8, 2023* The FirstPower 5.0Ah 14.4V Compatible with Roomba Battery Replacement has truly exceeded my expectations.

Not good enough Note: the company read my review and contacted me. They sent me out 2 new batteries to replace the ones I bought. Changing to 5 stars. This is a quality company that actually cares about their customers.
