I have a 551 and notice you do not specifically list this model, while you list 550 and 552. Is ok to use on 551?

Works on both the 550/551 and other 500 series versions.

Does it work with roomba 625?

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.

RemotesLost mine need a nother one

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.
