Review: Fits just like OEM battery! - It's a drop in direct replacement for OEM part. No compatability issue at all. Has been charging and working just like the original. The long term test will be how many charge discharge cycles it lasts but thus far no surprises!
Review: Replacement for our 4yr old Roomba. - Bought this battery as a replacement to the stock battery that came with our Roomba. The stock battery is about 4yrs old and run time started to decline. After 25-30mins, our Roomba would stop in its tracks in the middle of a job. I found this replacement and installed it right away. Installation was a breeze. Now, our Roomba can complete jobs with out suddenly stopping. I believe the full charge lasts about hour or so. Which is perfect in our case and what we need it for.

## Questions & Answers

**Q: 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?**
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.
