Can I use this tenergy replacement battery for iRobot Roomba 555? Thanks.

Don't buy it from Tenergy. I had the battery for about 8 months before it died. It should last at least a year. Their warranty is insufficient and the product is not the quality you would want. I asked them to replace the battery and the politely refused.

What is the warranty on this item?

We offer a 1 year warranty on this product. If you have any questions or need technical support, please contact us at amazon@tenergy.com or at 510-979-9969. We would love to help!

will this battery replace the 770 model vacuum battery, and will it run the 90 minutes the original does?

Yes. Amazon shows it as a replacement battery for 500, 600, & 700 series. Specs and form match up to my eyes. My experience is that Roomba runs about 90 minutes on it and cleans 1200 sqft with no problem.
